Renowned paleoanthropologist and integrative biology professor Tim White of the University of California, Berkeley will discuss his team’s amazing discoveries in African deserts and other locations around the world as the sixth recipient of the annual Richard H. and Glenda G. Rosenblatt Lectureship in Evolutionary Biology, scheduled for 3 p.m. on April 26. The lecture is free, open to the public and set to happen at the Scripps Seaside Forum, 8610 Kennel Way. White and his colleagues, who have worked in the Afar desert of Ethiopia for the last 25 years, have discovered a series of human ancestor fossils dating back nearly six million years. They garnered worldwide attention in 2009 with the discovery of Ardipithecus, a human ancestor that lived some 4.4 million years ago, likely soon after the dawn of humankind.
