The Friedkin site in Texas has yielded more pre Clovis projectile points from approximately 15.5kya.

Are the reports of H. sapiens outside of Africa ~200kya due to flawed interpretation of the dating data?

Genetic studies of Africa are giving light to ancient human population evolution there during the Pleistocene.

A large part of the DNA left to modern humans from interbreeding with Neandertals is related to fighting off viruses.

Neandertals practiced their own form of health care and it was crucial to their survival.

Modeling the disappearance of Neandertals through population dynamics.

A Neandertal child in Poland from 42 kya was eaten by a large bird.

Homo antecessor had already evolved Neandertal-type teeth 450,000 years ago.

H. erectus:
