And when the team looked at data on y-chromosomes, which pass intact from father to son, as well as their mitochondrial data, they were able to draw some tentative conclusions about Neanderthal communities.
Neanderthals surely hunted animals too, but there weren't enough of them, or they didn't stay in one place long enough, for the foxes to adapt to scavenging off their dinner plates.
They have inherited about 4% to 6% of their genes from the Denisovans, in addition to the 2.5% average Neanderthal genes present in all non-African humans.
