Harvard anthropologist Richard Wrangham theorizes in his new book, the Goodness Paradox, that Homo sapiens (us) is a domesticated species and, lacking ancient aliens as seen on the History channel or divine intervention, that we are self-domesticated. He believes that the domestication process was accomplished by our egalitarian hunter/gatherer ancestors by killing off potential leaders that would create a hierarchical society and eliminated their aggressive tendencies from the gene pool - thus creating a domesticated species. In this episode, the Edifice of trust host, Victor Bolles looks at evolutionary consequences this process has created and how humans have coped with them.
