Foxes hunt small animals.

And when other predators, including us, kill large animals, foxes are known to scavenge on the leftovers.

Now, a study of their scavenging shows that foxes have slyly relied on people for food for tens of thousands of years.

I saw that foxes benefit a lot today from humans, and I was wondering if this is also

the case in the past.

Chris Bauman, from the University of Tubingen's Institute for Scientific Archaeology.

Humans may have had a hand in driving the extinction of large herbivores,

like mammoths and mastodons, in the late Pleistocene,

which ended around 12,000 years ago.

But we inadvertently helped other species,

and Bauman suspects that Pleistocene-era foxes may have been among them.

So Bauman and his team obtained the remains of 70 foxes found in southwestern Germany.

They ranged from around 42,000 years ago when Neanderthals lived in the area to some 30,000 years ago,

when Homo sapiens came to dominate the region.

In this study, we analyzed the bone collagen of the foxes and saw that there are indeed
