This is entirely unsurprising given what’s been seen in our primate cousins. They’ve been observed going to war with neighboring tribes, slaughtering all the males, slaughtering the young offspring of those makes months later, and taking the females for themselves. War, genocide, infanticide, rape…all the things we think of as “inhuman” and unnatural are practiced by our close relatives. Fighting an outgroup which shares less of your genes than your tribe seems pretty normal in nature and makes the origin of racism pretty intuitive, and yet we think of racism as some particularly Western/American cultural failure.
