Hang on, has another paper from the PNAS special issue on “The Modern View of Domestication” broken embargo? An article from the Washington University comms machine ((No, wait, it’s two papers from that PNAS special issue that WU is promoting. This other one basically says that domesticated livestock have interbred with their wild relatives more that we have thought.)) lays out the difference between animal and plant domestication. Apparently, plant domesticators targeted genes that were insensitive to epistasis (i.e., the effect of other genes) and the environment, whereas animal domesticators did not. Maybe PNAS should just give up? Oh yeah, it has.
