Some 150 years after Charles Darwin proposed that we have a common ancestor with great apes, human evolution remains one of the most debated topics in all of science. In HHMI’s 2011 Holiday Lectures on Science, three world experts will delve into millions of years of evidence that scientists use to study human evolution and the fact and fiction of this important topic.

John J. Shea of Stony Brook University will explain how ancient stone tools provide evidence of problem solving. Sarah Tishkoff of the University of Pennsylvania will examine the genetic heritage of modern humans and human evolution. And Timothy D. White of the University of California, Berkeley, will describe the fossil evidence that links modern humans to our earliest relatives.

This year’s lecture series—Bones, Stones, and Genes: The Origin of Modern Humans—will take place in front of an audience of high school students October 6–7 at HHMI’s headquarters in Chevy Chase, Maryland. Sign up now for the live webcast at www.hhmi.org/biointeractive.
