Cleveland Museum of Natural History Explorer Lecture Series with Nicholas Wade, science reporter for The New York Times, discussing what the rapidly advancing field of DNA research is revealing about humanity's past. The ancestral human population of 50,000 years ago may have been very different from present-day people. But it had established the principal institutions of human societies, such as trade, warfare and religion. Humans also had developed a fully articulate modern language, which enabled them to break out of Africa. As they traveled to other regions of the world and adapted to different conditions on each continent, it is clear now that human evolution continued vigorously.
