William Von Hippel is a Professor of Psychology at the University of Queensland and Author of The Social Leap. Today is nothing short of fascinating as we learn the story of how our ancestors went from being chimps in trees to bipedal apes out on the plains and why we took that dangerous step in our development. We discover why our brains more than trebled in size and how that benefited us, what tools and tactics enabled these early humans to survive in a perilous new environment and what the implications are for our modern day minds dealing with primitive motivations.
