A team of researchers has uncovered new information that contradicts the current migration timeline. The current timeline mentions that humans may have arrived in North America 13,000 years ago, but the new research might push the date back to 30,000 years ago.
Previous research and conclusions shared by researchers argued that humans arrived in North and South America 13,000 years ago, with the most obvious proof being relics associated with the Clovis culture. However, the exact timeframe and methods used to reach the American continents have been a hot topic for a long time.
Exploring the timeline
The arrival of humans in North and South America is a major timeline for human civilization, and many researchers have tried to explore and analyze available information in an attempt to track down new insights. A significant number of relics have also been collected from ancient sites.
Another study has argued that the date should be pushed back to approximately 18,000 years ago. This study and the newer one were focused on the Chiquihuite Cave, which is located in Zacatecas, Mexico. They also offer new data and perceptions on 42 historic sites spread across North America and Beringia.
By working together, the authors of the two studies have found new evidence that signals the presence of a human that can be traced back to the Last Glacial Maximum, an event that took place between 19,000 and 26,000 years ago.
New stone tools that have been uncovered in the Mexican cave seem to be at least 30,000 years old. Instead of taking the Beringia route, which is thought to have been blocked by glacers within that timeframe, humans may have followed a different path along the Pacific Coast, but the details remain elusive for now.
More data can be found in a new study, which was published in a scientific journal.
