hey dude do you know the name of the species that was around before homo erectus that had a larger frontal lobe than us and was significantly physically stronger.

i remeber reading a chapter about them in a text book basically stating that man and this species where together and man managed to train canines to an extent that they hunted for food and drove them out of extinction.

i know im not making itup, but i cant find alot on it

cheers ali
