We’re Still Here


02 Jan

To go along with Thursday’s post about the Denisovans (I didn’t give their name), we have proof that ancient modern humans bred with both the Neanderthals and the Denisovans. In fact, I think you could argue that modern humans might not exist if it hadn’t been for the interbreeding.

DNA tests using information from bone marrow registries show that more than half of our immune system related DNA comes from Neanderthals and Denisovans. Without that, some disease may have wiped us off the planet.

While we don’t know what happened to them, I think we can say, they saved us.
