Humans settled in North America 17,000 years EARLIER than previously believed, study finds

Bones of an adult mammoth and its calf were found at a 37,000-year-old slaughterhouse in New Mexico. This suggests that humans settled North America 17,000 years earlier than previously thought.

A team of scientists led by the University of Texas at Austin have extracted collagen from bones, allowing them to be carbon-dated to settlement ages between 36,250 and 38,900 years.

The bones were found in 3-foot-high piles, 95% of which were adult, and characterized by carcass scars and fractures from blunt force impact.

The find adds to growing evidence that a society existed before people crossed the Bering Strait land bridge about 20,000 years ago. Also called Beringia, the bridge connected Siberia and Alaska during the last Ice Age and allowed people to come from Asia to North America.

The study’s lead author, Timothy Rowe, told DailyMail.com that ancient humans likely came from Asia, but whether they reached the Americas via coastal route or land. Another study in 2021 found that some of the first Americans stopped and paddled along a series of islands that were above sea level during the last Ice Age. It turns out that he crossed the Bering Sea.

Previous research has found ancient human remains dating back 20,000 years and other artifacts that suggest the area was inhabited before Clovis. However, mammoth bones are the earliest evidence ever discovered.

Scientists have found a pile of 3-foot-tall mammoth bones belonging to an adult female and her calf. However, 95% of her bones were adult.

“It’s not a charismatic place with beautiful skeletons lying around. It’s all squashed. But that’s the story,” Lowe said in a statement.

This discovery was also made in Lowe’s backyard. His neighbor found a tusk sticking out of the ground and immediately called a team to help excavate it.

Once most of the dirt had been removed, it revealed an open-air slaughterhouse containing various areas separated by walls made of stone and clay.

Both adult and calf mammoth bones were found stacked in piles, on top of which were placed adult heads and tusks.

The bones were found in an open-air butcher shop containing separate areas separated by walls.

Most of the artifacts in the heap are of adults, including 44 broken skull fragments, an intact upper right second molar, 12 isolated tooth plates, 25 ribs divided into 52 fragments, 3 There were 15 vertebrae, 15 vertebrae fragments, and 32 percussion impacted bone fragments. , 9 “butterfly fragments”, 20 unidentified bone fragments and 267 bags of small “bone fragments”.

“The adult face (tusks, premaxilla, and partial maxilla) was the single largest and heaviest element in existence, and was placed on top of a pile of bones,” said the journal Frontiers in Ecology and Read the research published in Evolution.

“It has been sheared from the skull at the nostrils, and its upper alveoli are broken and empty.

“The calf is represented by a partial left maxilla and dentary with intact dentition, three isolated tooth plates, left tibial diaphysis, and ten rib fragments.”

The study also notes that the separation of adult facial bones from the skull was due to “the most severe skull fractures.”

Before the mammoth bones were discovered, they were buried in Montana 20,000 years ago and were the earliest evidence of human settlement in North America.

In 1968, construction workers found ancient tools and the remains of a young child at the site.

This is the oldest genome ever recovered from the New World, and artifacts found with the remains indicate that the boy was part of the Clovis culture that crossed the Bering Strait land bridge. increase.

The so-called Anzic skeletons were found in about 125 artifacts, including tools made from the grooved spear points and antler of Clovis, and were covered in red ocher, a type of mineral.

Eske Willerslev of the University of Copenhagen, Denmark, who led the study, said: “The Clovis boy’s family is the direct ancestor of approximately 80% of all present-day Native Americans.

“Clovis’ culture is gone, but its people are still alive today.”
