One of the most interesting subjects in both History and Science is the early beginnings of humankind. There are several theories on how the first humans came to America, but the scientists’ aim is to come with a concrete one. They think they might have found it; or, at least, are closer to it.
One of the most controversial theories is the point through each the first Americans made it to the land: is it North or not? It has been believed that the first humans to spread across the Americas were the Clovis people, coming from Northern lands, such as Alaska and Siberia. Their gate to the continent was a corridor which opened because of climate changes, and this is how they got to come to Southern parts.
What the new study points out is the Clovis were not the first humans in the Americas. What’s more, it seems that they didn’t even use the ice corridor to make it to the new lands. New evidence shows that Clovis people had been living in Southern parts before the climate change and that the corridor didn’t have the necessary features to allow humans to use it.
The new theory is that the first humans came by boat to the Americas, via the Pacific Ocean. People living in parts where Chile is located nowadays had been there before the Clovis people.
The scientists based their research on the evolution of plants and animals as well because they are in strong connection to the human evolution. They found that other forms of evolution (plants and animals) around the ice corridor were not sufficiently developed, nor abounding such that they could not allow humans to use them as food.
Another study on the evolution of bisons, led by Peter D. Heintzman (University of California, Santa Cruz), reached the same conclusions, namely that life forms around the corridor were not sufficiently developed at that time in order to allow human migration. The main author, Peter D. Heintzman, declared for The Christian Science Monitor:
“They both suggest that the corridor opened too late for it to be the route for initial colonization of the Americas south of the ice.”
The study was published on August 10, in Nature (journal).
