I feel this bit tracks with experience.
When animals are bred for co-operation, as we once did with wolves to produce dogs, they become more like their infants. In a fascinating 40-year experiment starting in the 1950s, Russian foxes were bred for docility. Over the period, adult foxes become more and more like large cubs, spending more time playing, and developing drooping ears, floppy tails and patterned coats. Humans similarly have some characteristics of infantile apes – large heads, small mouths and, significantly here, finer body hair.The reason I keep thinking we're all acting like superannuated babies is because we are being bred for co-operation... bred to take orders... bred to want to take orders....
And the better we come to understand epigenetics the more complete will be the domestication.
