Prehistoric humans may have arrived the Americas earlier than previously thought: study

The video discusses the discovery of early settlers in Chiquihuite Cave, Central Mexico, dating back 33,000 years. This suggests that the first settlers crossed from Siberia to Alaska earlier than previously thought. Researchers found stone tools and used radiocarbon dating to confirm their age. The tools were made from limestone, a harder material than jasper, which was used by the Clovis culture. The video also explores new theories on migration routes, suggesting settlers traveled down the West Pacific Coast instead of through Canada due to limited resources.
