This lecture discusses human diversity and evolution. It argues that while the human form has been biologically fixed for over 50,000 years, culture has continued to evolve rapidly. Tracing human migration out of Africa using genetics, the lecture shows that humans today are not meaningfully divided into biological races, as nearly all genetic variation exists within populations. More recent human evolution has occurred culturally through developments like agriculture and urbanization, leading to more complex social systems over the past 10,000 years.
