I'm confused by this article. It says "New evidence adds to work showing people made these prints [in New Mexico] sometime between 21,000 and 23,000 years ago." It supposedly contradicts experts' belief for decades that "the first people in the Americas migrated from Siberia across the Bering Strait on a land bridge exposed during the last glacial maximum, sometime between 26,500 and 19,000 years ago.
How is that contradictory?
