For instance, recent papers by the likes of Eric Wang & John Hawks have found that genetic changes accelerated over the past 10,000 years or so with the development of agriculture and population expansions. A fair fraction are neurological and likely to affect behavior in some way. For example, you see new versions of SLC6A4, a serotonin transporter, in Europeans and Asians. There’s a new version of a gene (DAB1) that shapes the development of the layers of the cerebral cortex in east Asia. More of these will be identified and understood as the cost of sequencing drops.

More recent books like New York Times science writer Nicholas Wade’s ‘Before the Dawn’ or ‘The 10,000 Year Explosion: How Civilization Accelerated Human Evolution’ fill in the gaps.
