Humans may have been in North America much earlier than previously thought. Here’s the evidence: chipped rocks, crushed mastodon bones, and reliable dates showing the remains are 130,000 years old. Is that enough to rewrite the history? SAPIENS co-hosts Chip Colwell and Jen Shannon talk to Steven and Kathleen Holen, archaeologists and co-authors of a controversial discovery. And they further evaluate the claims with the help of anthropologist Todd Braje.
