They are releasing a major paper on Kennewick man, very cool stuff! This was a major find, a high quality skeleton preserved in the mud flats of the Columbia river in Washington state.
He had the legs of a pro soccer player, the arms of a wrestler, and an overuse injury from spear throwing - which he was probably very good at. His diet was mostly marine mammals (seals and sea lions), meaning he lived on the coast and not where he was found, and he is Asian by DNA and genetically unrelated to modern Native American / First Peoples. Great stuff! I love science.
Doesn't exactly favor the "early man ate mostly bananas & scavenged rotting kills" angle at all.

Also, this is a great book: The Humans Who Went Extinct: Why Neanderthals Died Out and We Survived: Clive Finlayson: 9780199239191: Books
