Further evidence points to footprints in New Mexico being the oldest sign of humans in Americas

Fossilised human footprints might be the oldest direct evidence that people lived in the Americas thousands of years earlier than thought — as early as 23,000 years ago. Researchers analysed pollen and sediment from the footprints and found that their ages matched estimates from 2021 that were based on the ages of seeds stuck in the fossils. The finding supports the idea that people skirted down the Pacific coast of the Americas after crossing the Bering land bridge, rather than waiting until ice-age glaciers retreated from inland routes. The timeline is also supported by indirect evidence, such as pendants carved from animal remains, but the footprints in New Mexico are special because they were undoubtedly made by people.
