STATES CHRONICLE – The first people arrived in North America 15, 000 years ago. It was well-known that they crossed a spit of land connecting Alaska and Siberia and made their way south between melting glaciers. However, according to a new study, it does seem that this theory is not true. Researchers said that humans could not be able to go through that corridor until about 12, 600 years ago. So how did the first humans populated North America?
The authors of the study suggested that they probably migrated along the Pacific coast. They extracted DNA and found out it was impossible for a human to survive in the ice-free corridor. The scientists tried to make a clear picture of how and when different flora and fauna emerged. This could help them discover when the ice-covered landscape became a passageway humans could use having no problem.
According to the study, it was impossible for humans to travel the corridor earlier than 12, 600 years ago. They did not have wood, tools or animals to feed with. So there must have been another route the first humans used to populate North America. This is the first theory against the one that we all have learned at school. Of course, there are people who disagree with it. However, the authors of the study do not seem to be bothered. They said it was great, from a science point of view, that they did not completely agree. This means that, in the future, more researchers will be interested in finding out the truth.
Who were the people that arrived first on these lands? Most of the archaeologists say the early inhabitants were called Clovis. The name was chosen after stone tool artefacts were found in Clovis, New Mexico. Whether these people were Clovis or not, it does not matter. The corridor could not be passed no matter what as there were no resources for the humans to live.
North America is now the third largest continent by area and the fourth by population. It is bordered by the Arctic Ocean (North), the Atlantic Ocean (East), the Pacific Ocean (West) and by South America (South). It has many regions and subregions, but the most popular are the United States of America, Canada, and Mexico.
What do you think? Who were the first humans who populated North America and which way they used to get there?
