There’s fresh drama in the field of human origins! A new analysis of an ancient hominid skull from China challenges what we thought we knew about our ancestral family tree, and its timeline—at least according to the researchers who wrote the paper. The new study claims that Homo sapiens, and some of our relatives, could have emerged at least half a million years earlier than we thought. But big claims require big evidence.

Anthropologist John Hawks joins Host Flora Lichtman to piece together the details.

Guest: Dr. John Hawks is an anthropologist and professor at the University of Wisconsin-Madison.
