Antonio Regalado is providing us with a recent series of the arguably best informed (compared to Guardian, Nature news etc.) popular science articles on genomics and its relevance to modern eugenics (embryo selection or genetic engineering) as well as the group differences causation question. As background for some of these, I had […]
