Genetic tests on roughly 6,000-year-old skeletons excavated in Colombia show no clear match to modern Colombians or to previously sequenced ancient individuals from nearby regions. The remains have only a distant genetic affinity with some modern Panamanians who speak Chibchan languages. The discovery complicates prevailing views of early migration into the Americas and highlights how much of our species' prehistoric diversity remains undocumented. Popular Mechanics editors John Gilpatrick and Jamie Sorcher explore the scientific and human implications in an episode of "The Astounding Pop Mech Show."
