Floppy Friendliness

Stable domestication by artificial selection is a haphazard process, prone to producing unpredictable biological effects alongside desired traits like docility or fertility. Biologists Don Newgreen and Jeffrey Craig have written a post on one such recurring cluster of oddities- an example was noted by that avid student of animal breeding, Charles Darwin: “Not a single domestic animal can be named which has not in some country drooping ears”. Newman & Craig’s text is an accessible look at a common embryological origin for many of the seemingly unconnected common characteristics of domestication, proposed by Adam Wilkins, Richard Wrangham and Tecumseh Fitch in the journal Genetics.
