Where do humans come from? Who were our ancestors? What makes us distinct from them? And why are we homo sapiens the only kind of people left on the planet? These are some of the big questions paleoanthropologist Chris Stringer has spent his life trying to answer. Thanks to recent scientific advances and anthropological discoveries, Stringer thinks we’re closer than ever to understanding the vast journey of human evolution. He joins us Tuesday to present his theories on the origins of humankind.

Chris Stringer is a researcher at the Natural History Museum in London and a Fellow of the Royal Society. He has authored more than two hundred books and papers on the subject of human evolution.

On October 16 the Smithsonian Institution is opening an exhibit on human evolution at the public library in Cedar City, Utah. The traveling exhibit features content from the Smithsonian Museum's Hall of Human Origins and it runs through November 12. Special programming at the exhibit will be provided for educators and clergy members, and a community conversation on human evolution. DETAILS
