Human DNA in an Oregon Cave Is 1,000 Years Older Than It Should Be — It Breaks the Clovis Story

In 2002, a University of Oregon field school began pulling dried lumps out of the floor of a cave in the Oregon high desert. Six years later, one of them held the oldest human DNA ever recovered in the Americas: around 14,300 years old, more than a thousand years before Clovis. Then the argument started, and it ran for twelve years. This is the full record of the Paisley Caves, the Oregon cave discovery that broke the Clovis First model of how ancient humans reached North America. What Dennis Jenkins and the University of Oregon actually found. Who attacked the claim, by name, in the pages of Science, and on what grounds, including the argument that modern human urine had soaked down through the sediment and contaminated a coyote dropping. The experiment the team ran to test that, dating the digested plant fibre and the water-soluble carbon of the same specimen separately, twelve times. The Western Stemmed projectile points that showed a tool tradition Clovis did not father. And the 2020 fecal lipid chemistry that finally settled whether those coprolites were human at all. Including the part most retellings leave out, which is that the critics were partly right. Also covered: what the site does not prove. It does not identify a culture, it does not establish a migration route, and it is not the earliest evidence of people in the Americas, because the White Sands footprints in New Mexico are dated between 23,000 and 21,000 years ago. And it says nothing about the identity of any living people. A maternal lineage is not a nation. No ancient aliens. No lost civilisation. No suppressed evidence. Every claim in this video is sourced to the excavation team, the peer-reviewed literature, and the institutions that hold the site.
