The Adaptable Hand-Axe and Human Origins
Richard Potts, Ph.D.
In 1942, Louis and Mary Leakey started scientific work at Olorgesailie, one of Africa's most renowned Acheulean hand-axe sites. Modern dating methods now make Olorgesailie the most precisely dated site in the world spanning the past 1 million years. Potts, the director of the Smithsonian's Human Origins Program, suggests that rather than exhibiting a prolonged period of unchanging human behavior prior to the origin of Homo sapiens, the hand-axe maker could adapt to dramatic environmental variability and colonized ecological communities throughout Africa. This California Academy of Sciences lecture will take place at the Jewish Community Center of San Francisco at 8 pm. Tickets ($8) can be purchased by calling 415-750-7128 or at the door, when available.
JCC: 3200 California Street, San Francisco.
