As Williams (1996, p. 118) points out,<\/span><\/p>\n<p><span style=\"color: #800000;\">anisogamy marks the start of male exploitation of females. \u201cWhen egg-<\/span><\/p>\n<p><span style=\"color: #800000;\">producers reproduce, they must bear the entire nutritional burden of nur-<\/span><\/p>\n<p><span style=\"color: #800000;\">turing the offspring.

First, the cost to the female<\/span><\/p>\n<p><span style=\"color: #800000;\">of abandoning the embryo or newborn is far greater than to the male. At any<\/span><\/p>\n<p><span style=\"color: #800000;\">given point in time she has made the greater commitment to the offspring<\/span><\/p>\n<p><span style=\"color: #800000;\">(in terms of time and energy) and will suffer a higher replacement cost if she<\/span><\/p>\n<p><span style=\"color: #800000;\">deserts it (all the more true in humans, where her reproductive future is<\/span><\/p>\n<p><span style=\"color: #800000;\">truncated by menopause). Second, internal fertilization introduces uncer-<\/span><\/p>\n<p><span style=\"color: #800000;\">tainty about paternity. While a female need never doubt that the offspring<\/span><\/p>\n<p><span style=\"color: #800000;\">to which she gives birth is her own, males must entertain the possibility of<\/span><\/p>\n<p><span style=\"color: #800000;\">cuckoldry. The degree of paternal care depends, across species, on the male\u2019s<\/span><\/p>\n<p><span style=\"color: #800000;\">certainty that he is the biological father. Doubt reduces the likelihood of<\/span><\/p>\n<p><span style=\"color: #800000;\">male investment and leaves the mother \u201cholding the baby.\u201d For these rea-<\/span><\/p>\n<p><span style=\"color: #800000;\">sons, in over 90% of mammals, it is the female who exclusively cares for the<\/span><\/p>\n<p><span style=\"color: #800000;\">young. As primates, humans are remarkable on three counts. First, they<\/span><\/p>\n<p><span style=\"color: #800000;\">must cope with a very protracted period of infant dependency. Babies are<\/span><\/p>\n<p><span style=\"color: #800000;\">born, biologically speaking, about nine months prematurely so that the huge<\/span><\/p>\n<p><span style=\"color: #800000;\">cranium can pass through the pelvis\u2014a channel that could not grow larger<\/span><\/p>\n<p><span style=\"color: #800000;\">without compromising the mother\u2019s bipedal locomotion. Sexual maturity is<\/span><\/p>\n<p><span style=\"color: #800000;\">not attained for 12 to 14 years because an extensive learning period is re-<\/span><\/p>\n<p><span style=\"color: #800000;\">quired to master the complexity of the social environment that humans<\/span><\/p>\n<p><span style=\"color: #800000;\">must navigate. Second, humans display a very high degree of paternal care<\/span><\/p>\n<p><span style=\"color: #800000;\">relative to other primates. Men did not elect this route as a favor to<\/span><\/p>\n<p><span style=\"color: #800000;\">women\u2014selection does not favor strategies that sel\ufb02essly bene\ufb01t others at a<\/span><\/p>\n<p><span style=\"color: #800000;\">net cost to the donor. Polygyny (men taking multiple mates) can offer huge<\/span><\/p>\n<p><span style=\"color: #800000;\">reproductive bene\ufb01ts to a man, but the sheer mathematics of the situation<\/span><\/p>\n<p><span style=\"color: #800000;\">mean that a high proportion of the less desirable will fail to reproduce at<\/span><\/p>\n<p><span style=\"color: #800000;\">all\u2014and may not even survive the intense degree of male competition that<\/span><\/p>\n<p><span style=\"color: #800000;\">polygyny engenders. The prizes are high, but the odds are strongly stacked<\/span><\/p>\n<p><span style=\"color: #800000;\">against winning. For most men, it would be more advantageous to remain<\/span><\/p>\n<p><span style=\"color: #800000;\">with one woman and increase the likelihood of their joint offspring surviv-<\/span><\/p>\n<p><span style=\"color: #800000;\">ing than to court multiple women whose offspring had a low survival prob-<\/span><\/p>\n<p><span style=\"color: #800000;\">ability for lack of male investment. Third, human males are also notable for<\/span><\/p>\n<p><span style=\"color: #800000;\">the degree of control that they exercise over their mates. These three facts<\/span><\/p>\n<p><span style=\"color: #800000;\">are not unconnected. The high and protracted dependence of young grow-<\/span><\/p>\n<p><span style=\"color: #800000;\">ing humans means that they bene\ufb01t from care by both parents. These long-<\/span><\/p>\n<p><span style=\"color: #800000;\">term costs are only likely to be met by males who have high levels of paternal<\/span><\/p>\n<p><span style=\"color: #800000;\">certainty.

Therefore, the former locus reflects female history, and the latter, male history.

Our ABM simulates agents with individual life cycles, including life events such as reaching maturity or menopause. We implemented two main mating systems: polygynandry and polygyny with different degrees in between. In each mating system, the male population can be either homogeneous or heterogeneous. In the latter case, some males are \u2018alphas\u2019 and others are \u2018betas\u2019, which reflects the extent to which they are favored by female mates. A heterogeneous male population implies a competition among males with the purpose of signaling as alpha males. The introduction of a heterogeneous male population is found to reduce by a factor 2 the probability of finding equal female and male TMRCAs and shifts the distribution of <\/span><em><span style=\"color: #800000;\">r<\/span><\/em><em><span style=\"color: #800000;\"><sub>F<\/sub><\/span><\/em><span style=\"color: #800000;\"><sub>\/<\/sub><\/span><em><span style=\"color: #800000;\"><sub>M<\/sub><\/span><\/em><span style=\"color: #800000;\">rF\/M to higher values.

They \ufb01rst took shape in the<\/span><\/p>\n<p><span style=\"color: #800000;\">era of behaviorist learning theory. The account was a simple one; parents<\/span><\/p>\n<p><span style=\"color: #800000;\">treat boys and girls differently, reinforcing the correct behavior in each. Boys<\/span><\/p>\n<p><span style=\"color: #800000;\">are encouraged to \ufb01ght, climb trees, and play football. Girls are forced to<\/span><\/p>\n<p><span style=\"color: #800000;\">wear dresses, play with dolls, and share. The \u201cBaby X\u201d paradigm was hailed<\/span><\/p>\n<p><span style=\"color: #800000;\">as conclusive evidence of socialization differences (e.g., Will, Self, &amp; Datan,<\/span><\/p>\n<p><span style=\"color: #800000;\">1976). A six-month-old baby was wrapped in a blue or a pink blanket, iden-<\/span><\/p>\n<p><span style=\"color: #800000;\">ti\ufb01ed as a boy or a girl, then handed to a woman who was asked to look after<\/span><\/p>\n<p><span style=\"color: #800000;\">it for a few minutes. When told it was a girl, the women more often offered<\/span><\/p>\n<p><span style=\"color: #800000;\">the infant a doll in preference to other toys. Surely this showed that parents<\/span><\/p>\n<p><span style=\"color: #800000;\">treat infants differently as a function of their biological sex?<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">But there was a problem. Despite many attempts at replication, the ef-<\/span><\/p>\n<p><span style=\"color: #800000;\">fect seemed even weaker than it had on \ufb01rst sight appeared (and recall the<\/span><\/p>\n<p><span style=\"color: #800000;\">effect was found only for toy selection\u2014there were no differences in social<\/span><\/p>\n<p><span style=\"color: #800000;\">behavior to the infant). It was certainly not strong enough to support the<\/span><\/p>\n<p><span style=\"color: #800000;\">whole edi\ufb01ce of sex differences (Stern &amp; Karraker, 1989). And even if par-<\/span><\/p>\n<p><span style=\"color: #800000;\">ents gave their children different toys, such a \ufb01nding would be trivial unless<\/span><\/p>\n<p><span style=\"color: #800000;\">it could be shown that the toys changed the child\u2019s subsequent behavior. But<\/span><\/p>\n<p><span style=\"color: #800000;\">the real challenge came when Lytton and Romney (1991) collected from<\/span><\/p>\n<p><span style=\"color: #800000;\">around the world 172 studies that had examined the way in which parents<\/span><\/p>\n<p><span style=\"color: #800000;\">treat their sons and daughters. Considering them all together, the evidence<\/span><\/p>\n<p><span style=\"color: #800000;\">for differential treatment was virtually nil. Parents did not differ in the<\/span><\/p>\n<p><span style=\"color: #800000;\">amount of interaction with the child, the warmth they showed, their ten-<\/span><\/p>\n<p><span style=\"color: #800000;\">dency to encourage either dependency or achievement, their restrictiveness,<\/span><\/p>\n<p><span style=\"color: #800000;\">their use of discipline, their tendency to reason with the child, or the amount<\/span><\/p>\n<p><span style=\"color: #800000;\">of aggression that they tolerated. There was one area that showed a differ-<\/span><\/p>\n<p><span style=\"color: #800000;\">ence. Parents tended to give their children sex-appropriate toys. But sex-<\/span><\/p>\n<p><span style=\"color: #800000;\">differentiated toy preference has been found in infants from nine months of<\/span><\/p>\n<p><span style=\"color: #800000;\">age (Campbell, Shirley, Heywood, &amp; Crook, 2000). Children play more<\/span><\/p>\n<p><span style=\"color: #800000;\">with sex-appropriate toys even when their parents do not speci\ufb01cally en-<\/span><\/p>\n<p><span style=\"color: #800000;\">courage them to do so (Caldera, Huston, &amp; O\u2019Brien, 1989). It is quite likely<\/span><\/p>\n<p><span style=\"color: #800000;\">that parents are not using toys to turn their children into gender conformists<\/span><\/p>\n<p><span style=\"color: #800000;\">but are simply responding to the child\u2019s own preferences.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>Didnt know of that meta-analysis. Heres the abstract:<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">A meta-analysis of 172 studies attempted to resolve the conflict between previous narrative reviews on whether parents make systematic differences in their rearing of boys and girls. Most effect sizes were found to be nonsignificant and small. In North American studies, the only socialization area of 19 to display a significant effect for both parents is encouragement of sex-typed activities. In other Western countries, physical punishment is applied significantly more to boys. Fathers tend to differentiate more than mothers between boys and girls. Over all socialization areas, effect size is not related to sample size or year of publication. Effect size decreases with child&#8217;s age and increases with higher quality. No grouping by any of these variables changes a nonsignificant effect to a significant effect. Because little differential socialization for social behavior or abilities can be found, other factors that may explain the genesis of documented sex differences are discussed. <\/span><\/p>\n<p>&nbsp;<\/p>\n<p>Probably, a newer one exist by now. But interesting nonetheless.<\/p>\n<p>&nbsp;<\/p>\n<p>&#8211;<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">Anyway, if parents\u2019 behavior toward their children was being guided by<\/span><\/p>\n<p><span style=\"color: #800000;\">their desire for them to conform to traditional gender stereotypes than we<\/span><\/p>\n<p><span style=\"color: #800000;\">would expect to \ufb01nd that the most sex-typed adults have the most sex-typed<\/span><\/p>\n<p><span style=\"color: #800000;\">children.

This was co-opted into<\/span><\/p>\n<p><span style=\"color: #800000;\">an explanation of sex differences by proposing that children selectively im-<\/span><\/p>\n<p><span style=\"color: #800000;\">itate their same-sex parent. Laboratory studies were done in which children<\/span><\/p>\n<p><span style=\"color: #800000;\">were exposed to adult \u201cmodels\u201d performing a variety of novel behaviors. If<\/span><\/p>\n<p><span style=\"color: #800000;\">social learning theorists were right, then the statistical analysis would show<\/span><\/p>\n<p><span style=\"color: #800000;\">a signi\ufb01cant interaction between sex-of-model and sex-of-child\u2014girls would<\/span><\/p>\n<p><span style=\"color: #800000;\">imitate women and boys would imitate men. Dozens of such studies failed<\/span><\/p>\n<p><span style=\"color: #800000;\">to \ufb01nd such an effect (Huston, 1983; Maccoby &amp; Jacklin, 1974). Perry and<\/span><\/p>\n<p><span style=\"color: #800000;\">Bussey (1979) devised an ingenious experiment that avoided the pitfalls of<\/span><\/p>\n<p><span style=\"color: #800000;\">the previous studies, where children had a one-off exposure to an adult<\/span><\/p>\n<p><span style=\"color: #800000;\">model. They showed children a \ufb01lm of eight adults selecting a preferred<\/span><\/p>\n<p><span style=\"color: #800000;\">fruit. In one condition all four men made one choice (e.g., orange), while all<\/span><\/p>\n<p><span style=\"color: #800000;\">four women made another (e.g., apple). In another condition, three men and<\/span><\/p>\n<p><span style=\"color: #800000;\">one woman chose an orange while three women and one man chose an<\/span><\/p>\n<p><span style=\"color: #800000;\">apple. In another condition half the men chose oranges and half the women<\/span><\/p>\n<p><span style=\"color: #800000;\">chose apples. They found that the extent to which children copied an adult<\/span><\/p>\n<p><span style=\"color: #800000;\">preference depended upon the proportion of their sex that made that<\/span><\/p>\n<p><span style=\"color: #800000;\">choice. In the \ufb01rst condition, there was a high degree of same-sex imitation,<\/span><\/p>\n<p><span style=\"color: #800000;\">in the second a much smaller amount, and in the third, there was no signif-<\/span><\/p>\n<p><span style=\"color: #800000;\">icant difference between the girls and boys in their choices. What this sug-<\/span><\/p>\n<p><span style=\"color: #800000;\">gested was that children were not slavishly imitating a same-sex adult but<\/span><\/p>\n<p><span style=\"color: #800000;\">rather judging the appropriateness of a particular (in this case wholly arbi-<\/span><\/p>\n<p><span style=\"color: #800000;\">trary) preference on the basis of the proportion of male or female adults who<\/span><\/p>\n<p><span style=\"color: #800000;\">made it. These results helped to make sense of previous work, which had<\/span><\/p>\n<p><span style=\"color: #800000;\">already shown that children tended to imitate activities that they already<\/span><\/p>\n<p><span style=\"color: #800000;\">knew to be sex-typed regardless of the sex of the model who was currently<\/span><\/p>\n<p><span style=\"color: #800000;\">engaged in it (Barkley, Ullman, Otto, &amp; Brecht, 1977). What was important<\/span><\/p>\n<p><span style=\"color: #800000;\">was the child\u2019s internal working model of gender and behavior.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>Interesting.<\/p>\n<p>&nbsp;<\/p>\n<p>&#8211;<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">Many developmentalists had already rebelled against the thoroughly passive<\/span><\/p>\n<p><span style=\"color: #800000;\">view of the child constructed by learning theory. Martin and Halverson<\/span><\/p>\n<p><span style=\"color: #800000;\">(1981) argued that children have a natural tendency to think categorically.<\/span><\/p>\n<p><span style=\"color: #800000;\">They form categories about all sorts of things, from animals to sports, and it<\/span><\/p>\n<p><span style=\"color: #800000;\">would be surprising if they did not, very early in life, form categories of male<\/span><\/p>\n<p><span style=\"color: #800000;\">and female. Once these categories are formed, all incoming information that<\/span><\/p>\n<p><span style=\"color: #800000;\">is gender-related gets shunted into the correct binary slot, and over time a<\/span><\/p>\n<p><span style=\"color: #800000;\">stereotype is built up about what males and females look like, do, and enjoy.<\/span><\/p>\n<p><span style=\"color: #800000;\">It is this internal model or gender schema, not the surveillance of parents,<\/span><\/p>\n<p><span style=\"color: #800000;\">which drives the child toward sex-appropriate behavior. At the very same<\/span><\/p>\n<p><span style=\"color: #800000;\">time that this proposal was being offered for child development, Bem<\/span><\/p>\n<p><span style=\"color: #800000;\">(1974) was proposing an identical scheme to explain adult differences in<\/span><\/p>\n<p><span style=\"color: #800000;\">sex-typing. The degree to which we \u201ctype\u201d information as gender-relevant<\/span><\/p>\n<p><span style=\"color: #800000;\">is an individual difference variable. Women who strongly sex-type informa-<\/span><\/p>\n<p><span style=\"color: #800000;\">tion become more stereotypically feminine than women who are less in-<\/span><\/p>\n<p><span style=\"color: #800000;\">clined to tag information with gender labels. The cognitive revolution had<\/span><\/p>\n<p><span style=\"color: #800000;\">come to sex differences: it was not a matter of behavioral training, it was a<\/span><\/p>\n<p><span style=\"color: #800000;\">matter of mental categorizing, organizing, and recalling.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">But gender schema theory was so cognitive that it left no room for an<\/span><\/p>\n<p><span style=\"color: #800000;\">adapted mind. The cracks inevitably began to appear. One problem was tim-<\/span><\/p>\n<p><span style=\"color: #800000;\">ing: sex differences in toy choice, play styles, activity levels, and aggression<\/span><\/p>\n<p><span style=\"color: #800000;\">are found as early as two years of age (Brooks &amp; Lewis, 1974; Fagot, 1991;<\/span><\/p>\n<p><span style=\"color: #800000;\">Freedman, 1974; Howes, 1988; Kohnstamm, 1989; O\u2019Brien &amp; Huston,<\/span><\/p>\n<p><span style=\"color: #800000;\">1985; Roopnarine, 1986), but children are not able to correctly sort pic-<\/span><\/p>\n<p><span style=\"color: #800000;\">tures of boys and girls into piles until their third year (Weinraub, Clements,<\/span><\/p>\n<p><span style=\"color: #800000;\">Sockloff, Ethridge, &amp; Myers, 1984). Children prefer sex-congruent toys<\/span><\/p>\n<p><span style=\"color: #800000;\">before they are able to say whether the toy is more appropriate for a boy or<\/span><\/p>\n<p><span style=\"color: #800000;\">a girl (Blakemore, LaRue, &amp; Olejnik, 1979). They prefer to interact with<\/span><\/p>\n<p><span style=\"color: #800000;\">members of their own sex and show sex differences in social behavior before<\/span><\/p>\n<p><span style=\"color: #800000;\">they can label different behaviors as being more common among boys or<\/span><\/p>\n<p><span style=\"color: #800000;\">girls (Serbin, Moller, Gulko, Powlishta, &amp; Colburne, 1994; Smetana &amp;<\/span><\/p>\n<p><span style=\"color: #800000;\">Letourneau, 1984). Longitudinal studies con\ufb01rm that sex-typed behavior<\/span><\/p>\n<p><span style=\"color: #800000;\">does not wait upon gender labeling (Campbell, Shirley, &amp; Candy, under re-<\/span><\/p>\n<p><span style=\"color: #800000;\">view; Fagot &amp; Leinbach, 1989; Trautner, 1992). A second problem was<\/span><\/p>\n<p><span style=\"color: #800000;\">correspondence: even when children\u2019s gender stereotypes crystallize and<\/span><\/p>\n<p><span style=\"color: #800000;\">peak at about seven years of age, there is no relationship between a child\u2019s<\/span><\/p>\n<p><span style=\"color: #800000;\">gender knowledge and how sex-stereotypic their own behavior is (Serbin<\/span><\/p>\n<p><span style=\"color: #800000;\">et al., 1994; Martin, 1994; Powlishta, 1995). Children seem to need neither<\/span><\/p>\n<p><span style=\"color: #800000;\">the ability to discriminate the sexes nor an understanding of gender stereo-<\/span><\/p>\n<p><span style=\"color: #800000;\">typic behavior to show sex differences.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>Didnt know this! Very cool.<\/p>\n<p>&nbsp;<\/p>\n<p>&#8211;<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">During the last twenty years there has been a signi\ufb01cant change in the<\/span><\/p>\n<p><span style=\"color: #800000;\">nature of women\u2019s labor, as women have moved into many arenas tradi-<\/span><\/p>\n<p><span style=\"color: #800000;\">tionally occupied by men. We might therefore expect to see a shift in both<\/span><\/p>\n<p><span style=\"color: #800000;\">stereotypes and self-perceptions by men and women. No such shift has<\/span><\/p>\n<p><span style=\"color: #800000;\">occurred (Helmreich, Spence, &amp; Gibson, 1982; Lewin &amp; Tragos, 1987;<\/span><\/p>\n<p><span style=\"color: #800000;\">Lueptow, 1985; Lueptow, Garovich, &amp; Lueptow, 1995). Furthermore, we<\/span><\/p>\n<p><span style=\"color: #800000;\">would expect to see a fair degree of cultural speci\ufb01city, with \u201ctraditional\u201d so-<\/span><\/p>\n<p><span style=\"color: #800000;\">cieties showing more marked stereotypes than more egalitarian ones. We do<\/span><\/p>\n<p><span style=\"color: #800000;\">not (Williams &amp; Best, 1982). Social role theory supposes that sex differences<\/span><\/p>\n<p><span style=\"color: #800000;\">are responsive to stereotypes and hence that stereotypes should be more ex-<\/span><\/p>\n<p><span style=\"color: #800000;\">treme and polarized than actual sex differences. They are not (Swim, 1994).<\/span><\/p>\n<p><span style=\"color: #800000;\">We are left with the alternative suggestion that stereotypes are reasonably<\/span><\/p>\n<p><span style=\"color: #800000;\">accurate assessments of the typical differences between men and women.<\/span><\/p>\n<p><span style=\"color: #800000;\">Rather than stereotypes causing sex differences, the reverse is the case. If this<\/span><\/p>\n<p><span style=\"color: #800000;\">is true, then we at least have a means of explaining the typical division of<\/span><\/p>\n<p><span style=\"color: #800000;\">labor between the sexes (women elect to spend more time than men do in<\/span><\/p>\n<p><span style=\"color: #800000;\">parenting activities). Although Eagly acknowledges that two biological fac-<\/span><\/p>\n<p><span style=\"color: #800000;\">tors (gestation and lactation in women, and size and strength in men) may<\/span><\/p>\n<p><span style=\"color: #800000;\">be implicated in the division of labor, for her biology stops at the neck: \u201cThis<\/span><\/p>\n<p><span style=\"color: #800000;\">viewpoint assumes that men and women have inherited the same evolved<\/span><\/p>\n<p><span style=\"color: #800000;\">psychological dispositions\u201d (Eagly &amp; Wood, 1999, p. 224). While anisogamy<\/span><\/p>\n<p><span style=\"color: #800000;\">may have forced the reproductive burden upon women, Eagly and Wood<\/span><\/p>\n<p><span style=\"color: #800000;\">make the implausible argument that there has been no commensurate adap-<\/span><\/p>\n<p><span style=\"color: #800000;\">tation of their goals, strategies, or preferences.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">Nobody can seriously doubt that environmental and cultural factors in-<\/span><\/p>\n<p><span style=\"color: #800000;\">\ufb02uence the expression of sex differences. But to acknowledge the impact of<\/span><\/p>\n<p><span style=\"color: #800000;\">culture upon the surface structure of femininity is not to say that gender has<\/span><\/p>\n<p><span style=\"color: #800000;\">no biological basis and that the nature of men and women is wholly con-<\/span><\/p>\n<p><span style=\"color: #800000;\">structed by society.

Jensen wrote in <em>The g Factor<\/em> p. 433 that:<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">Of the approximately 100,000 human polymorphic genes, about 50,000 are <\/span><\/p>\n<p><span style=\"color: #800000;\">functional in the brain and about 30,000 are unique to brain functions.1121 The <\/span><\/p>\n<p><span style=\"color: #800000;\">brain is by far the structurally and functionally most complex organ in the human <\/span><\/p>\n<p><span style=\"color: #800000;\">body and the greater part of this complexity resides in the neural structures of <\/span><\/p>\n<p><span style=\"color: #800000;\">the cerebral hemispheres, which, in humans, are much larger relative to total <\/span><\/p>\n<p><span style=\"color: #800000;\">brain size than in any other species. A general principle of neural organization <\/span><\/p>\n<p><span style=\"color: #800000;\">states that, within a given species, the size and complexity of a structure reflect <\/span><\/p>\n<p><span style=\"color: #800000;\">the behavioral importance of that structure. The reason, again, is that structure <\/span><\/p>\n<p><span style=\"color: #800000;\">and function have evolved conjointly as an integrated adaptive mechanism. But <\/span><\/p>\n<p><span style=\"color: #800000;\">as there are only some 50,000 genes involved in the brain\u2019s development and <\/span><\/p>\n<p><span style=\"color: #800000;\">there are at least 200 billion neurons and trillions of synaptic connections in the <\/span><\/p>\n<p><span style=\"color: #800000;\">brain, it is clear that any single gene must influence some huge number of <\/span><\/p>\n<p><span style=\"color: #800000;\">neurons\u2014 not just any neurons selected at random, but complex systems of <\/span><\/p>\n<p><span style=\"color: #800000;\">neurons organized to serve special functions related to behavioral capacities.<\/span><\/p>\n<p><span style=\"color: #800000;\">It is extremely improbable that the evolution of racial differences since the <\/span><\/p>\n<p><span style=\"color: #800000;\">advent of Homo sapiens excluded allelic changes only in those 50,000 genes <\/span><\/p>\n<p><span style=\"color: #800000;\">that are involved with the brain.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>An analogous case is true for another biological group distinction: men and women. Given the possibility of sex-linked genes, it seems entirely unreasonable to expect evolution never to make use of this for the brain. Indeed, we know this isnt the case because hormones are partly controlled in the brain. Why then <em>apriori<\/em> exclude other sex-linked genes for the brain? <strong>It makes no sense at all, and is a clear case of prejudiced opinions.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>That being said, it is now known that there are actually fewer genes in humans than estimated when Jensen wrote that in 1998.

In that letter, Sociobiologywas being connected to nazism and racism,<\/span><\/p>\n<p><span style=\"color: #800000;\">and Wilson was said to support a conservative agenda by emphasizing the<\/span><\/p>\n<p><span style=\"color: #800000;\">genetic underpinnings of human behavior. Actually, though Wilson\u2019s book<\/span><\/p>\n<p><span style=\"color: #800000;\">was more than 500 pages long, only the last chapter was devoted to the<\/span><\/p>\n<p><span style=\"color: #800000;\">human species. There he argued that a number of behaviors, including sex<\/span><\/p>\n<p><span style=\"color: #800000;\">roles, aggression, altruism, and even moral and religious beliefs, could well<\/span><\/p>\n<p><span style=\"color: #800000;\">have a biological basis.

The critics, however, argued that<\/span><\/p>\n<p><span style=\"color: #800000;\">Wilson had no evidence and that his statements supported a biological de-<\/span><\/p>\n<p><span style=\"color: #800000;\">terminist view of humans.

And<\/span><\/p>\n<p><span style=\"color: #800000;\">among his critics could be found two of Wilson\u2019s Harvard colleagues,<\/span><\/p>\n<p><span style=\"color: #800000;\">Richard Lewontin and Stephen J.

The<\/span><\/p>\n<p><span style=\"color: #800000;\">high point of criticism was a sociobiology symposium at the 1978 meeting<\/span><\/p>\n<p><span style=\"color: #800000;\">of the American Association for the Advancement of Science in Washing-<\/span><\/p>\n<p><span style=\"color: #800000;\">ton, DC, where a group of activists (from the antiracist group Committee<\/span><\/p>\n<p><span style=\"color: #800000;\">Against Racism) chanted \u201cRacist Wilson, you can\u2019t hide, we charge you<\/span><\/p>\n<p><span style=\"color: #800000;\">with genocide!\u201d whereupon two of them poured a pitcher of ice water on<\/span><\/p>\n<p><span style=\"color: #800000;\">Wilson\u2019s neck, shouting, \u201cWilson, you are all wet!\u201d<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>wtf<\/p>\n<p>&nbsp;<\/p>\n<p>&#8211;<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">In 1975 the critics bene\ufb01ted from the political climate in which bio-<\/span><\/p>\n<p><span style=\"color: #800000;\">logical explanations of humans were taboo. This was a time when the lib-<\/span><\/p>\n<p><span style=\"color: #800000;\">eral credo reigned. There was the spirit of the post\u2013World War II UNESCO<\/span><\/p>\n<p><span style=\"color: #800000;\">declaration stating that no evidence for racial differences existed, and the<\/span><\/p>\n<p><span style=\"color: #800000;\">general agreement to restrict genetic explanations of humans to the \ufb01eld of<\/span><\/p>\n<p><span style=\"color: #800000;\">medicine. This was also the time of postwar \u201cenvironmentalism\u201d (or, rather,<\/span><\/p>\n<p><span style=\"color: #800000;\">culturalism); people like Margaret Mead in anthropology and B. F. Skinner<\/span><\/p>\n<p><span style=\"color: #800000;\">in psychology were still held in high regard. And just before the sociobiology<\/span><\/p>\n<p><span style=\"color: #800000;\">debate, as a warning for all, there had been the controversy about IQ around<\/span><\/p>\n<p><span style=\"color: #800000;\">psychologist Arthur Jensen\u2019s (1969) suggestion that the 15-point difference<\/span><\/p>\n<p><span style=\"color: #800000;\">in measured IQ between whites and blacks could have a genetic explana-<\/span><\/p>\n<p><span style=\"color: #800000;\">tion. Wilson had actually been careful with IQ and race in his book, and even<\/span><\/p>\n<p><span style=\"color: #800000;\">covered his back by citing Lewontin\u2019s (1972) discovery that variation be-<\/span><\/p>\n<p><span style=\"color: #800000;\">tween populations (races) is much smaller than variation within a popula-<\/span><\/p>\n<p><span style=\"color: #800000;\">tion (race), a point that was widely regarded as undermining the usefulness<\/span><\/p>\n<p><span style=\"color: #800000;\">of race as a biological concept. But for the critics, that was not enough. What<\/span><\/p>\n<p><span style=\"color: #800000;\">mattered to them was the fact that Wilson had dared discuss biological un-<\/span><\/p>\n<p><span style=\"color: #800000;\">derpinnings for human behavior at all. This is why he had to be forcefully<\/span><\/p>\n<p><span style=\"color: #800000;\">denounced as a \u201cbad\u201d scientist, both morally and scienti\ufb01cally.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">In 1975 many believed the critics when it came to Wilson\u2019s political<\/span><\/p>\n<p><span style=\"color: #800000;\">motives. Very few ever read his book or asked about his actual agenda\u2014or,<\/span><\/p>\n<p><span style=\"color: #800000;\">for that matter, about the critics\u2019 agenda.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>The treatment of the various IQ researchers is also worth reading about. I refer to Nyborg, Helmuth. &#8220;The greatest collective scientific fraud of the 20th century: The demolition of differential psychology and eugenics.&#8221; <em>Mankind Quarterly, Spring Issue<\/em> (2011).<\/p>\n<p><a href=\"http:\/\/www.helmuthnyborg.dk\/Global-Witch-Hunt\/Collective%20Fraud%20Publication_MQLI3Nyborg.pdf\">http:\/\/www.helmuthnyborg.dk\/Global-Witch-Hunt\/Collective%20Fraud%20Publication_MQLI3Nyborg.pdf<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&#8211;<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">The members of Science for the People were genuinely convinced that so-<\/span><\/p>\n<p><span style=\"color: #800000;\">ciobiology was, indeed, evil.

The working logic of the critics is worth examining more<\/span><\/p>\n<p><span style=\"color: #800000;\">closely. It involved a type of \u201ccognitive coupling\u201d between three things: bad<\/span><\/p>\n<p><span style=\"color: #800000;\">science, ideological in\ufb02uences, and bad consequences.

Bad<\/span><\/p>\n<p><span style=\"color: #800000;\">science was never the kind of science that the critics did themselves in their<\/span><\/p>\n<p><span style=\"color: #800000;\">own labs. Bad science was science that involved working with models and<\/span><\/p>\n<p><span style=\"color: #800000;\">statistics of various sorts, not science at the molecular, reductionist level.<\/span><\/p>\n<p><span style=\"color: #800000;\">For many critics, the molecular level was where the \u201creal\u201d truth lay.

Often, one sex of offspring is more likely to be neglected, abused, or<\/span><\/p>\n<p><span style=\"color: #800000;\">even killed than the other. Female infanticide is the most common pattern<\/span><\/p>\n<p><span style=\"color: #800000;\">(see Dickemann, 1979b for an evolutionary analysis), but male-biased in-<\/span><\/p>\n<p><span style=\"color: #800000;\">fanticide has also been reported (e.g., among the Ayoreo of Bolivia by<\/span><\/p>\n<p><span style=\"color: #800000;\">Bugos &amp; McCarthy, 1984). Much of my own research has focused on a pat-<\/span><\/p>\n<p><span style=\"color: #800000;\">tern of daughter favoritism among the Mukogodo of Kenya, an impover-<\/span><\/p>\n<p><span style=\"color: #800000;\">ished and low-status group of Maasai-speaking pastoralists (Cronk, 1989,<\/span><\/p>\n<p><span style=\"color: #800000;\">1991b, 2000). Although there is absolutely no evidence that the Mukogodo<\/span><\/p>\n<p><span style=\"color: #800000;\">abuse their children or have ever practiced infanticide, I have documented<\/span><\/p>\n<p><span style=\"color: #800000;\">in a variety of ways a broad tendency on the part of Mukogodo parents to<\/span><\/p>\n<p><span style=\"color: #800000;\">favor their daughters over their sons. For example, Mukogodo mothers and<\/span><\/p>\n<p><span style=\"color: #800000;\">other caregivers tend to hold infant girls more often than infant boys and to<\/span><\/p>\n<p><span style=\"color: #800000;\">remain closer to them when not holding them. In addition, girls are nursed<\/span><\/p>\n<p><span style=\"color: #800000;\">longer and more frequently and are more likely to be taken for medical care<\/span><\/p>\n<p><span style=\"color: #800000;\">than boys. The results of this favoritism include better growth performance<\/span><\/p>\n<p><span style=\"color: #800000;\">by Mukogodo girls than boys (measured as height-for-age, weight-for-age,<\/span><\/p>\n<p><span style=\"color: #800000;\">and weight-for-height). Survivorship among young girls is so much better<\/span><\/p>\n<p><span style=\"color: #800000;\">than among boys that the sex ratio of children ages 0\u20134 years is 67 boys to<\/span><\/p>\n<p><span style=\"color: #800000;\">every 100 girls.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">A number of explanations for this daughter favoritism are possible. For<\/span><\/p>\n<p><span style=\"color: #800000;\">example, it might be that Mukogodo parents favor their daughters because<\/span><\/p>\n<p><span style=\"color: #800000;\">of the bridewealth payments, usually consisting of several head of cattle and<\/span><\/p>\n<p><span style=\"color: #800000;\">some sheep and goats, that they attract. However, there is no correlation<\/span><\/p>\n<p><span style=\"color: #800000;\">between how many daughters a man has married off and either his herd<\/span><\/p>\n<p><span style=\"color: #800000;\">size, the number of wives that he himself is subsequently able to marry, or<\/span><\/p>\n<p><span style=\"color: #800000;\">the number of wives that his sons are subsequently able to marry. Further-<\/span><\/p>\n<p><span style=\"color: #800000;\">more, although all of the groups surrounding the Mukogodo also demand<\/span><\/p>\n<p><span style=\"color: #800000;\">bridewealth payments, they show no signs of daughter favoritism. A better<\/span><\/p>\n<p><span style=\"color: #800000;\">explanation is that the Mukogodo are responding to the relatively good<\/span><\/p>\n<p><span style=\"color: #800000;\">prospects of their daughters compared to their sons. Mukogodo women vir-<\/span><\/p>\n<p><span style=\"color: #800000;\">tually all get married, often to wealthy men from neighboring ethnic<\/span><\/p>\n<p><span style=\"color: #800000;\">groups. Mukogodo men, on the other hand, often have a hard time accu-<\/span><\/p>\n<p><span style=\"color: #800000;\">mulating the necessary bridewealth and frequently must delay marriage<\/span><\/p>\n<p><span style=\"color: #800000;\">until middle age or forgo marriage entirely because of their general poverty<\/span><\/p>\n<p><span style=\"color: #800000;\">and low ethnic status.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">The Mukogodo pattern of daughter favoritism \ufb01ts predictions made<\/span><\/p>\n<p><span style=\"color: #800000;\">by evolutionary biologist Robert Trivers and mathematician Dan Willard<\/span><\/p>\n<p><span style=\"color: #800000;\">(1973). They noted that if the reproductive prospects of male and female<\/span><\/p>\n<p><span style=\"color: #800000;\">offspring differ in a way that is predictable from the parents\u2019 condition dur-<\/span><\/p>\n<p><span style=\"color: #800000;\">ing the time of investment, natural selection would favor parents who invest<\/span><\/p>\n<p><span style=\"color: #800000;\">more heavily in that sex with the better reproductive prospects. Because in<\/span><\/p>\n<p><span style=\"color: #800000;\">many species the variance in reproductive success is greater for males than<\/span><\/p>\n<p><span style=\"color: #800000;\">for females, the conditions faced by an individual during development will<\/span><\/p>\n<p><span style=\"color: #800000;\">typically have a greater impact on the reproductive success of males than<\/span><\/p>\n<p><span style=\"color: #800000;\">females. The net result is often that males reared when conditions are good<\/span><\/p>\n<p><span style=\"color: #800000;\">will outreproduce their sisters, while females reared when conditions are<\/span><\/p>\n<p><span style=\"color: #800000;\">bad will outreproduce their brothers. The Mukogodo appear to be in the<\/span><\/p>\n<p><span style=\"color: #800000;\">latter situation: Due to their poverty and low status, girls\u2019 prospects are<\/span><\/p>\n<p><span style=\"color: #800000;\">much better than boys\u2019, and it makes sense for Mukogodo parents to favor<\/span><\/p>\n<p><span style=\"color: #800000;\">their daughters. Although this pattern of daughter favoritism increases<\/span><\/p>\n<p><span style=\"color: #800000;\">Mukogodo parents\u2019 numbers of grandchildren, this is not simply a demon-<\/span><\/p>\n<p><span style=\"color: #800000;\">stration of the common folk wisdom that people like to have many grand-<\/span><\/p>\n<p><span style=\"color: #800000;\">children. In two surveys of Mukogodo women\u2019s reproductive goals and<\/span><\/p>\n<p><span style=\"color: #800000;\">preferences, I have found that they express a bias in favor of sons, not daugh-<\/span><\/p>\n<p><span style=\"color: #800000;\">ters, and Mukogodo parents appear to be entirely unaware of the daughter<\/span><\/p>\n<p><span style=\"color: #800000;\">favoritism in their behavior. Mukogodo daughter favoritism seems to be not<\/span><\/p>\n<p><span style=\"color: #800000;\">a conscious strategy for enhancing one\u2019s number of grandoffspring but,<\/span><\/p>\n<p><span style=\"color: #800000;\">rather, a deeply rooted evolved predisposition shared by a wide variety of<\/span><\/p>\n<p><span style=\"color: #800000;\">species that is triggered by speci\ufb01c environmental circumstances. This<\/span><\/p>\n<p><span style=\"color: #800000;\">demonstrates the value of an evolutionary approach in identifying circum-<\/span><\/p>\n<p><span style=\"color: #800000;\">stances that lead to patterns of child neglect of which even the parents them-<\/span><\/p>\n<p><span style=\"color: #800000;\">selves may not be aware.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>Interesting case study.<\/p>\n<p>&nbsp;<\/p>\n<p>&#8211;<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #800000;\">There is no single biosocial approach to the study of human behavior any more than there is a single environmental approach. David Buss (1990) identi\ufb01es three general biosocial approaches to the study of human behav- ior: evolutionary, behavior genetic, and physiological. Although they em- ploy different theories and methods, work with different units of analysis, and invoke different levels of causation, they are not the contradictory stew we \ufb01nd when we survey the plethora of strictly environmental theories in sociology. Besides having in common the tremendous potential to illumi- nate human nature, biosocial approaches are vertically integrated; i.e., their principles are conceptually consistent across all three levels of analy- sis. Although I concentrate on evolutionary psychology, all biosocial ap- proaches are so \u201cenvironment-friendly\u201d that I am tempted to call them \u201cbiologically-informed environmental approaches.\u201d Evolutionary psycho- logy will not (and cannot) cannibalize the social sciences. We will always need the social sciences, Barkow (1992, p. 635) assures us, but he also re- minds us that \u201cpsychology underlies culture and society, and biological evo- lution underlies psychology.\u201d That is all I am asking criminologists to accept.<\/span><\/p>\n<p>Possibly too much for them to accept.<\/p>\n<p>&#8211;<\/p>\n<p><span style=\"color: #800000;\">Few social scientists balk at the notion that human anatomy and physiology are products of evolution. We observe some aspect of complex morphology and infer that it was selected over alternate designs because it best served some particular function that proved useful in assisting the proliferation of its owners\u2019 genes. Although there is no other scienti\ufb01cally viable explana- tion for the origin of basic behavioral design, most social scientists probably dismiss the idea of human behavioral patterns as products of the same nat- ural process. If we accept the notion that evolution shaped our minds and our behavior, we have to accept that many of our less admirable traits such as deception, cheating, and violence owe their present existence to the fact that they were useful to the reproductive success (the total number of an or- ganism\u2019s descendants, and thus its genes) of our distant ancestors, as were more positive traits such as altruism, nurturance, and love.<\/span><\/p>\n<p>Can&#8217;t get the one without the other. So it is for the qualities that make men aggressive. Make make useful combatants, useful researchers and so on, but also criminals. It is the price society pays.<\/p>\n<p>&#8211;<\/p>\n<p><span style=\"color: #800000;\">How can criminal behavior, including such heterogeneous acts as murder, theft, rape, and assault, be conceived of as an evolved adaptation when it is clearly maladaptive in modern environments? First, because a behavior is currently maladaptive does not mean that mechanisms underlying it are not evolved adaptations (designed by natural selection to solve some environmental problem). Our modern environments are so different in many re- spects from the environments our species evolved in that traits and behav- iors selected for their adaptive value then may not be adaptive at all today. Conversely, traits and behaviors that appear to be adaptive today may not have a history of natural selection (Barkow, 1984; Daly, 1996; Mealey, 1995). An adaptation is a current feature with a past; a feature that is cur- rently adaptive may or may not have a future. Second, the speci\ufb01cs of crim- inal behavior (or of any other social behavior for that matter) are not themselves adaptations: \u201cGenes do not code themselves for jimmying a lock or stealing a car. . . . The genome does not waste precious DNA encoding the speci\ufb01cs\u201d (Rowe, 1996, p. 285).<\/span><\/p>\n<p>The author is right, but has anyone tested whether it actually <em>is<\/em> adaptive today as well? Do criminals have more kids than non-criminals? That seems quite likely! Which would mean that we are actually breeding for more criminal behavior!<\/p>\n<p>&#8211;<\/p>\n<p><span style=\"color: #800000;\">How do cheats manage to continue to follow their strategy given how grudgers respond to them when they are unmasked? In computer simula- tions of interactions between populations of cheats, suckers, and grudgers, cheats are always driven to extinction, as evolutionary theory would predict (Raine, 1993; Allman, 1994). The problem with such simulations is that players are constrained to operate within the same environment in which their reputations quickly become known. In the real world, cheats can move from location to location meeting and cheating a series of grudgers who are susceptible to one-time deception. This is exactly what we observe among the more psychopathic criminals. They move from place to place, job to job, and relationship to relationship, leaving a trail of misery behind them before their reputation catches up to them (Hare, 1993; Lykken, 1995). In mod- ern societies, cheats are much more likely to prosper in large cities than in small traditional communities, where the threat of exposure and retaliation is great (Ellis &amp; Walsh, 1997; Machalek &amp; Cohen, 1991; Mealey, 1995).<\/span><\/p>\n<p>Good observation about the &#8216;psychopaths&#8217; and cheaters. We really are setting up a good environment for cheaters. Interesting. The lack of ability to delete things from the internet will however counter this to some degree.<\/p>\n<p>&#8211;<\/p>\n<p><span style=\"color: #800000;\">It is a central tenet of evolutionary theory that the human brain evolved in the context of overwhelming concerns for resource and mate acquisition. When food, territory, and mates are plentiful, pursuing them violently is an unnecessary waste of energy involving the risk of serious injury or death. When resources become scarce, however, acquiring them any way one can may become worth the risk (Barkow, 1989). Among our ancestral males, those who were most successful in acquiring resources gained rank and sta- tus and, thereby, access to a disproportionate number of females. As Daly and Wilson (1988a, p. 132) have remarked: \u201cHomo sapiens is very clearly a creature for whom differential social status has consistently been associated with variations in reproductive success.\u201d Today status is not necessarily as- sociated with aggression and violence (typically, quite the opposite today in most modern societies), but it almost certainly was more so in our ancestral environments (Chagnon, 1996; Wrangham &amp; Peterson, 1998). As the species moved from a nomadic lifestyle to civilization, it was typically the most successful warriors that became a nation\u2019s aristocracy (Baumeister, Smart, &amp; Boden, 1996). Because females prefer males with rank and status, genes inclining males to aggressively pursue their interests (which sometimes meant becoming violent) enjoyed greater representation in subsequent gen- erations. From the evolutionary point of view, violence is something human males (as well as males in numerous other species) are designed by nature to do. Wherever we look in the world, males are far more likely than fe- males to be both the victims and the perpetrators of all kinds of violent acts (Badcock, 2000; Barak, 1998; Campbell, 1999).<\/span><\/p>\n<p>Actually a study found that being bullied predicts lack of dating. Being bullied is clearly a sign of low status. So, we should expect high status to predict dating.<\/p>\n<p><a href=\"http:\/\/www.epjournal.net\/wp-content\/uploads\/EP10253270.pdf\">http:\/\/www.epjournal.net\/wp-content\/uploads\/EP10253270.pdf<\/a><\/p>\n<p>&#8211;<\/p>\n<p><span style=\"color: #800000;\">Early hominids (Australopithecus anemensis and afarenis) were also 50% to 100% larger than females (Geary, 2000). The low degree of sexual di- morphism among modern Homo sapiens (males are only about 10% larger than females, on average) indicates an evolutionary shift from violent male competition for mates to a more monogamous mating system and an in- crease in paternal investment (Plavcan &amp; van Schaik, 1997). However, there is evidence in the archeological literature indicating that homicide was much more common in evolutionary environments than it is today (Edgerton, 1992). In cultures where polygyny and low paternal investment still exist, we \ufb01nd homicide rates greatly exceeding those of any modern society. The Agta have a rate of 326 per 100,000, and the Yanomamo one of 166 per 100,000 (Ellis &amp; Walsh, 2000, p. 71). Chagnon (1996) also presents data showing that homicide rates in many of today\u2019s pre-state societies are many times greater than in any modern industrial society. Indeed, because the Yanomamo practice polygyny, homicide translates directly into reproduc- tive success; males who have killed the most in intervillage warfare (and are thus the most respected) have about three times as many wives and chil- dren than those who have killed least or not at all (Chagnon, 1988).<\/span><\/p>\n<p>They must be very war like, breeding for such behavior for many years.<\/p>\n<p>&#8211;<\/p>\n<p><span style=\"color: #800000;\">We can accept without question that forced copulation increases \ufb01tness among nonhuman animals, but may \ufb01nd it distasteful to apply similar rea- soning to humans. If we claim that rape (or any other violent behavior) is a product of natural selection, aren\u2019t we justifying it and implying that it is morally acceptable? No, we are not; and to claim that we are is to commit the naturalistic fallacy, the confusion of is with ought.Nature simply is, what ought to be is a moral judgment, and to say that forced copulation is natural mammalian behavior no more constitutes moral approval than to claim that we approve of disease and death because we call these unwelcome events natural also. Rape in a modern context is a maladaptive consequence of a mating strategy that may have been adaptive in the environments in which our species evolved; it is a morally reprehensible crime that requires strong preventative legal sanctions. Calling something \u201cnatural\u201d does not dignify it or place it beyond the power of culture to modify, as manifestly it is not.<\/span><\/p>\n<p>Like with their previous comments, perhaps whatever makes males rape is actually still adaptive. One would have to check to see if rapists have more children than non-rapists. Probably need to rely on anonymous surveys, since not all rapists are actually in prison (they might have been).<\/p>\n<p>&#8211;<\/p>\n<p><span style=\"color: #800000;\">A third predictor of a person\u2019s reproductive strategy according to AAT (but not considered a factor in other evolutionary theories of crime) is in- telligence, with those of relatively high intelligence generally opting for par- enting effort and those of relatively low intelligence generally opting for mating effort. It is not assumed that low intelligence is intrinsically antiso- cial (or high intelligence intrinsically prosocial, for that matter), only that it makes the procurement of resources needed to advertise parental effort to prospective females problematic. Low intelligence also makes it dif\ufb01cult to learn and appreciate the moral norms of society. Thus, a strategy emphasiz- ing mating effort is similar to criminal behavior in that direct and immedi- ate methods are used to procure resources illegitimately; little thought is given to the consequences either to the self or to the victim (Gottfredson &amp; Hirschi, 1990). Conversely, parenting effort is embedded in a prosocial lifestyle in which resource procurement relies on the patient and intelligent accumulation of social and occupational skills that are attractive to females. Thus, reproductive strategies mirror antisocial\/prosocial behavior in terms of emphases on immediate versus delayed grati\ufb01cation.<\/span><\/p>\n<p>This is a question open to testing, and it has been. <em>g<\/em> is a stronger (negative) predictor of crime than is income, so the effect of <em>g<\/em> is not completely mediated by resources measured by income.<\/p>\n<p>There is also another question to test. It is known that there is a crime hotspot in IQ. From Jensen 1998:<\/p>\n<p><span style=\"color: #800000;\">The above-mentioned correlation between crime and IQ is clearly nonlinear. That is, the rate of serious crimes against persons, such as robbery, assault, rape, and homicide, is very low and nearly constant across IQ levels above IQ 100, but below IQ 100 the rate rises steeply, and then declines rapidly below IQ 70. The peak crime rate occurs in the IQ range from 75 to 90, with the highest rate for violent crime in the IQ range from 80 to 90. The vast majority of both petty crimes and violent crimes are committed by the segment of the population ranging from IQ 60 to 100. (So-called white-collar criminals and leaders of organized crime generally have IQs above 100.) These findings apply to both males and females, although the rate for most types of antisocial behavior is much lower for females, especially violent crime.<\/span><\/p>\n<p>On the evolutionary account, one would expect the hotspot to move when the population average moves. This is testable. In countries with all blacks in SS Africa, is the crime also committed by people 10 to 30 below the average?<\/p>\n<p>National IQ&#8217;s predict national crime rates too, which favors <em>g<\/em> theory. Here&#8217;s the table from Lynn 2012:<\/p>\n<p>[TABLE 9.1]<\/p>\n<p>&#8211;<\/p>\n<p><span style=\"color: #800000;\">The major concern of feminist criminology has long been to explain the uni- versal fact that women are far less likely than men to involve themselves in criminal activity (Price &amp; Sokoloff, 1995, p. 3). Whenever and wherever records have been kept, it has been found that males commit the over- whelming proportion of criminal offenses, and the more serious and violent the offense, the more males dominate in its commission (Campbell, 1999). This fact is not in dispute, although explanations of it are. The traditional sociological view of gender differences in crime and other forms of deviant behavior is that they are products of differential socialization: that men are socialized to be aggressive, ambitious, and dominant, women to be nurtur- ing and passive; and that women will be as antisocial and criminal as men with female emancipation. The majority of studies relating to this issue, however, actually support the opposite of the emancipation hypothesis: that is, as the trend toward gender equality has increased, females have tended to commit fewer rather than more crimes relative to males (Ellis &amp; Walsh, 2000, p. 388).<\/span><\/p>\n<p>This makes me wonder why, in their view, that they would WANT to &#8217;emancipate&#8217; women more, if the outcome is that women become just as violent as men! Are feminists inadvertently promoting more violence?<\/p>\n<p>&#8211;<\/p>\n<p><span style=\"color: #800000;\">Jerome Barkow asks us to \u201cimagine evolutionary biology and population genetics as one island continent, and the social-behavioral sciences as an- other. Now is the time for ending false dichotomies and for emphasizing continuities. Now is the time to position the social-behavioral sciences in their proper place as a seamless continuation of biology\u201d (1989, p. 18). To become vertically integrated in the way envisioned does not mean that crim- inologists need to become expert evolutionary psychologists, behavior ge- neticists, endocrinologists, or neuroscientists in order to study crime and criminality. They must at least be students of those sciences, however, if they are to develop theories that maintain vertical consistency with them. If they do not they will become irrelevant, as Alice Rossi (1984) warned bio- logically ignorant sex-role researchers in her 1983 presidential address to the American Sociological Association. In this \u201cdecade of the brain\u201d and in the age of the Human Genome and Human Genetic Diversity Projects, biolog- ical data relevant to understanding criminal behavior are pouring in at a re- markable rate. Criminologists have an unprecedented opportunity to join other scientists in interdisciplinary analyses of criminal behavior with these data.
