Evidence emerges from the history of America’s first humans

Scientists found footprints 23,000 to 21,000 years ago during studies in the state of New Mexico. When humans settled in the Americas has been a topic of debate for decades.

The latest findings could also overturn theories that humans landed on continents 16,000 years ago. The footprints are believed to belong to a group of children and adolescents walking by a lake thousands of years ago.

The results also indicate that there may have been several waves of migration to North America that we were not previously aware of. This means that the first human communities to migrate were wiped out from the face of the earth.

Researchers from the US Geological Survey (USGS) team found the footprints in the soft mud at the edge of a shallow lake near the White Sands Desert in New Mexico.

The USGS team performed radiocarbon dating work on seeds found above and below layers where footprints were found on layers of sediment. This allowed researchers to find a remarkably precise date.

Based on their size, scientists believe the footprints mostly belong to teens and children roaming the area, and adults are also included in these groups from time to time.

The new discoveries also provide a general framework for the life of the first known settlers in the Southwestern United States. Although scientists cannot come to a definitive conclusion about what teenagers do; He says they could help the adults hunt.

Hunted animals, on the other hand, have to be “dealt with in a very short time,” said Dr. Sally Reynolds, “You had to start a fire very quickly and extract the fat.

At this point, teens are believed to be performing tasks that need to be done quickly, such as picking up bushes, firewood, and carrying water to start a fire. The date of the new discovery is also very important as there are countless claims about the date of the first settlement in America. But over time, all theories have been disproved in one way or another.

The controversy continues over some tools made by processing stones. Discussions can go as far as whether these tools have taken this form over time in the natural environment with frictions and similar natural events, or whether they have been touched by human hands.

Tools from the time of the first natives do not give as clear a picture as the tools that were found 13,000 years ago to the present day and require serious craftsmanship.

One of the authors of the article published at Bournemouth University, Prof. Matthew Bennett said: “The reason there is so much controversy is that there isn’t really precise, clear and compelling data. We think we have that data now.” he says, “Footprints are not as controversial as stones. Footprints are footprints and cannot move between layers of soil.”

While the physical evidence is less questionable in nature, the researchers want to make sure that the evidence showing the history of the footprints is “literally waterproof.”

The article mentions a potential dating error called the “reservoir effect”. This causes old carbon to be recycled in natural aqueous environments and then mixed with the radiocarbon, making it appear to be older than it actually is.

The researchers say that when they dated this effect, there was no significant difference.

The radiocarbon dating expert from the University of Vienna, Prof. Tom Higham says that the waters in the area where people came and went at this time were considered to be very shallow and that there was no significant difference between the dates revealed in the two cases as a result of all the studies:

“Considering all the possibilities, I think the age of these traces is between 21,000 and 23,000 years.”

During the second half of the 20th century, a consensus emerged that the first peoples to set foot in the Americas were groups affiliated with the Clovis culture.

These top predators are believed to have moved from Siberia to Alaska via the Bering Strait during the last Ice Age, when water levels were very low. But in the 1970s, the unshakeable perception that the Clovis were the first humans to set foot in America was almost belied in light of some data.

In the 1980s, traces of people living 14,500 years ago were found in the Chilean region of Monte Verde. Since the 2000s, traces of the lives of people aged 15,500 years in the US state of Texas and 16,000 years in the state of Idaho have been found. Once again, evidence has emerged that humans may have lived in the US state of New Mexico during the last ice age.

Experts say these people may have crossed America by natural bridges formed by ice, and in this case, many other settler groups may have set foot in America at the same time.
