Humans have caused wild animals to shrink and domestic animals to grow, according to a new study out of the University of Montpellier in southern France. Researchers studied tens of thousands of animal bones from Mediterranean France covering the last 8,000 years to see how the size of both types of animals has changed over time.
The interesting part (which isn’t in the title or summary) is that the correlation reversed between the Roman and medieval eras—before 1,000 years ago, the wild and domestic populations were evolving in the same direction.
