Grok E evolved in Africa. He had a larger brain than previous species which led to toolmaking and fire. The larger brain required more energy and thus the meat eating became a much bigger part of the human diet. The need for meat coupled with toolmaking and intelligence lead to organized hunting and scavenging. Grok E migrated slowly throughout Africa and beyond after game, but did so in many waves. Last known pocket of Grok E's was in Asia about 200,000 years ago.
