American geologists announced based on detailed studies of footprints discovered in New Mexico that these footprints date back to 21,000 to 23,000 years ago. According to CNN, until these ancient footprints were discovered in the southern United States in 2021, scientists estimated the presence of humans in America to be between 13,000 to 20,000 years ago. However, precise geological studies and dating reveal that the timeline of human presence on the American continent is much older than previously assumed. According to the report, paleontologists, through radiocarbon studies of conifer pollen and the collection of about 75,000 pollen grains found in layers corresponding to the footprints, as well as using the optical stimulated luminescence dating technique on quartz grains in fossil sediments, determined the exact age of these footprints to be 21,500 years. Researchers stated that this study greatly aids in clarifying the grand narrative of human evolution, but many aspects regarding how populations formed on the American continent remain unknown. It is still unclear whether early humans entered America by boat or crossed a land bridge from Asia. Additionally, despite advancements in genetic evidence, it is uncertain whether one or multiple populations of early humans undertook this long journey. However, what is certain is that the findings of the new study generally indicate that the first humans entered south of New York City, Cincinnati, and Iowa around the time of the last ice age, a period between 19,000 to 26,000 years ago when two massive ice sheets covered one-third of northern North America.
First Humans Arrived in America 23,000 Years Ago; Results of Ancient Footprint Study Released
American geologists have determined that ancient footprints found in New Mexico date back to 21,000 to 23,000 years ago, suggesting that humans arrived in America much earlier than previously thought. This discovery challenges existing theories about human migration to the continent and highlights the need for further research into early human populations.
