Archaeological evidences, research and analysis continue to dock in some novel discoveries and facts. There is news which the readers have believed for some time. And, then it so happens that a totally different report comes up.
This is exactly what has been found out by the researchers from the University of Montreal. Before going into the depth of their finding, it is pertinent for the readers to know, that there have been exploration which indicated that humans came to the North America from 14,000 BC.
What do the latest researches indicate?
In accordance with the latest research the humans settled in the modern day Canada by 22,000 BC. Now, this is much before the 14,000 BC.
Which site was excavated for this conclusion?
The Bluefish Caves in Canada, which are in close vicinity to the Alaska Border, were excavated for the purpose. The archaeologist Jacques Cinq-Mars pursued the excavation amidst the year of 1977 and 1987.
The discovery was made possible by the process of radiocarbon dating of artifacts and animal bones found here.
How did the researchers come to this conclusion?
- In a recent experiment, the researchers pursued examination of almost 36,000 fragments of bones.
- This was a part of a 2-year project.
- It is in 15 bones that they found “undeniable traces of human activity”.
- Then, there were 20 other fragments which portrayed “probable” traces of human involvement.
- All these findings were then published.
Professor Ariane Burke had led the entire research in association with her PhD student Lauriane Bourgeon. She said-“Series of straight, V-shaped lines on the surface of the bones were made by stone tools used to skin animals,” She further added- “These are indisputable cut-marks created by humans.”
In accordance with Burke, the discovery is a confirmation of the previous analyses. It at the same time shows the earliest site of human settlement in Canada.
With the aid of radiocarbon dating it is possible to estimate the age of the artifacts, as in how old they are. Hence, the bones have been sent for the purpose. This is the result achieved by the process of radiocarbon dating:-
- The oldest fragment which was found was the horse’s jawbone.
- It dates back to between 23,000 and 24,000 years old.
- There are marks of stone tools, that the researchers believe was back then utilized to remove the animal’s tongue.
How did humans reach North America?
- The present Russia was back then Bering Strait.
- It is thus thought that humans reached North America by crossing the Bering Strait.
- The new date which is proposed for the same falls in the middle of the Ice age.
- Hence, the scientist said that the findings actually support the theory, which says that a small tribe of humans lived secluded in the Beringia region of northwestern Canada and north-eastern Russia for almost thousands of years.
- However, when thousands of years later the ice thawed, it was these tribes which travelled way down to the entire continent.
