The human being had already arrived in America 37,000 years ago!

Throughout its history, Man has left behind several clues to his presence and activities, such as carved stone tools. However, does the absence of such tools mean that Man was not present in a territory? The discovery of traces of butchery on mammoths in America indicates that our species was present on this continent as early as 37,000 years ago.

[EN VIDÉO] The mystery of the fourth mammoth is finally cleared up
In 150 years, only four mammoths have been discovered in France. Unearthed in Changis-sur-Marne, this specimen is particularly well preserved. This astonishing documentary by Inrap (National Institute for Preventive Archaeological Research) tells of a meticulous investigation to understand what happened to this animal.

The presence of thespecies human life on the New Continent is generally estimated by archaeologists thanks to the identification of remains of lithic industry. The oldest traces of an elaborate lithic industry in Europe date back to the Upper Palaeolithic revolution, around 45,000 years ago. This was then propagated in Siberia as well as in Asia, to finally be brought to America about 16,000 years ago. However, the date of introduction of such tools in America is widely associated by archaeologists with that, also, of the arrival of the human species on this continent. However, this last point has just been called into question by an international research team, which publishes an article in the newspaper Frontiers in Ecology and Evolution.

The authors of this study describe their discovery of the remains of mammoths at the locality of Hartley, located on the Colorado Plateau, in northern New Mexico. The remains consist in particular of a defense – which was already outcropping on the site -, ribs, a molarvertebrae and a mammoth jaw that belong to an adult female and her young.

Traces of butchery

Obsidian Clovis points, which are man-made projectiles, were also found at the site. The Hartley site had previously been identified as a probable butchery site, but the authors indicate that the remains of mammoths could be prior to the presence of the projectiles. The mammoth remains are disarticulated and piled to a depth of one meter and the bones of the skull Location

The analysis of collagen contained in one of the mammoth bones reveals that the specimen dates from around 37,000 years ago.

Short, wide, parallel marks on a rib are otherwise consistent with the use of coarse butchery tools and suggest that the ribs were systematically detached from the spine location.
The spine is located in the middle of the back, which it separates into its left and right sides. It rests on the pelvis, serves as a support for the ribs and the skull.

The disarticulation of the vertebrae as well as their perforation was also probably carried out in order to extract the fat more easily.

The authors finally indicate that the presence of traces of butchery and human activity in America 37,000 years ago is in agreement with the hypothesis according to which two distinct human groups colonized the Americas: one before the last glacial maximum ( -31,000 years ago) and the other about 16,000 years ago.
