Origin and diversity of sampled village dogs and wolves. This ability to process lipids indicates a dietary target of selection that was important when proto-dogs hunted and fed alongside hunter-gatherers. That’s not insignificant. Calibration of the molecular clock suggests that the ancestors of modern dogs formed a distinct lineage prior to the peak of the last ice age.
