Abstract: 
Dr Richard Wrangham’s book and YouTubes are helping to explain our evolved psychology as primarily occurring in African hunter-gatherer bands before the end of the last ice age. This perspective is supported by the exquisite cave paintings and tool artifacts from this ancient time. The most important evidence about our origins, however, comes from recent anthropological studies of current bands that represent the earlier age. Results showed that 5-psychosocial-behaviors produced both the environment and the natural selection for our psychology. These are: 1) language, coalitional activities and egalitarianism organization, 2) problems of bullies for egalitarianism, 3) management of the problems by gossip, ostracism and executions, 4) those targeted by the management had shorter lives and fewer children demonstrating strong natural selection, 5) reduced targeting occurred for those showing high-quality activities or high status, which increased the complexity of the selection to include all of our psychological abilities. The evolved psychological abilities include those highlighted by Dr Wrangham: emotions, intelligence, conscience and personality, as well as those with only supporting evidence: developmental and social learning, theory of mind, language, aesthetics, and free will. Further support for the importance of the 5-psychosocial-behaviors is provided by evidence from the domestication syndrome, natural selection pressure, and a positive feedback model. In addition, these perspectives can explain issues such as why 50% of our thoughts and behaviors comes from our environment and development as demonstrated in identical twin studies, and why we experience life with agency and free will. Dr Wrangham’s work is producing a new explanation of our nature that can help us all to understand why we are the way we are.
