On early human migration, geography and culture

By Kathleen Holder

Our species, Homo sapiens, left Africa earlier than previously thought and our diverse cultures have been heavily influenced by geography, according to a recent review by Alexander (Sandy) Harcourt, professor emeritus of anthropology at the University of California, Davis.

The paper grew out of a keynote address to a National Academy of Sciences colloquium in Irvine earlier this year on comparative phylogeography, the study of the geographic distribution of┬áspecies (Watch a video of Harcourt’s lecture below).
