Neanderthal And Humans Shared Cave
"The finding, primarily based on analysis of fossil remains, confirms earlier speculation that Neanderthals and humans competed with carnivores for food and prehistoric real estate."
It also strengthens the link between humans and Neanderthals, suggesting they did socialise and interbreed, despite some DNA evidence to the contrary.
Nothing that isn't going on in modern-day San Francisco.
That's fascinating.
