homo erectus?
An early hominid, first discovered in late nineteenth century, then called "Peking Man" and "Java Man." Given rightful and generally accepted place on human family tree by Lewis Leakey in the fifties. Believed to have used the most primitive stone tools and may have used fire. Expert opinion is divided on when exactly they went extinct but there is some evidence a few remaining colonies may have shared the planet continguously with Homo Neaderthalensis and modern Homo Sapiens Sapiens.
Clearly you are much deeper thinking than I am! LOL
