Tarzanthropus Boisei: “Human Ancestors More Rugged than Originally Thought, had powerful forearms well-suited for climbing trees”
If memory serves, he also had teeth and jaw muscles to eat his veggies. I’d thought he was in a parallel evolutionary path though. The new Homo Erectus skulls don’t fit as his descendent and may simplify the whole shooting match in favor of many variations of HE for a long period of time. I’d feel comfortable with that.
