The United States is under 250 years old, but some of its maximum archaeological sites are older than Vikings sailors, the Roman empire and the pyramids.

Many assistance say how the first humans arrived here in North America. It is a mystery precisely how and when other people arrived, although it is widely believed that they crossed the Bering Strait at least 15,000 years.

Some sites, such as White Sands and Cooper’s Ferry, have skeptics about the precision of their age. However, they give a contribution to our understanding of some of the first Americans.

Many of those puts are open to the public, so you can see the old story of yourself.

Prehistoric camels, mammoths and other giant people have traveled, which is now new, when it is greener and more humid.

While the weather warmed about 11,000 years ago, Lake Otero Water fell, revealing the digital footprints of humans who lived among those extinct animals. Some even to stick to a vague, providing a rare review of the habit of the old hunters.

“Where do they come from?” Feder said. “Not parachute to the new Mexico. They will have to come from another place, which means that there are still older places. ” Archaeologists have simply not discovered them yet.

While they can absorb white and homonymous sands, Pas’s footprints are prohibited lately.

In the 1970s, archaeologist James, Mr. Adovasio, caused controversy when he and his colleagues that the stone team and other artifacts discovered in southwest Pennsylvania belonged to humans who had lived in the region 16,000 years ago.

For decades, scientists have discovered evidence of human homes that seemed to have between 12,000 and 13,000 years, belonging to the Clovis culture. For a long time they would have been the first to cross the Bering land bridge. Humans who have arrived in North America before this organization are called before Clovis.

At that time, the skeptics said that evidence of appointments in the imperfect radiocarbon, AP News reported in 2016. During the years that followed, more places that seem greater than 13,000 years in the United States have been discovered.

Feder said that Advasio meticulously registered the site, but there is still no transparent consensus on the age of the oldest artifacts. However, he said: “This site is surely a vital, vital and vital site. ” This helped archaeologists realize that humans began arriving in the continent against the people of Clovis.

A site that has added intriguing evidence to the prior to the cloud is in the west of Idaho. Humans living there have stone equipment and carbonized bones in a house between 14,000 and 16,000 years, according to the radiocarbon dating. Other researchers approached the dates 11,500 years ago.

These rod teams are other Clovis harassed projectiles, researchers wrote in a 2019 clinical magazine.

Cooper’s ferry is in the classic nose of the Perce nose, which the land administration office has in public property.

They also discovered a mastodon defense with what seemed to reduce the marks through a tool. Other scientists have returned to the site more recently, raising more bones and tools. They used a radiocarbon dating, which established the site as a pre-clavis.

“The stone machinery and on the site show that at 14,550 years, other people knew how to locate the game, the new water and the device to make machinery,” said Michael Waters, one of the researchers, in a press release in 2016 “. ” These other people were well suitable for this environment. “

Scientists examine coprolitos or fossilized peanut, to be informed more about long and fast animals diets. Mineralized tea can also reveal much more. In 2020, archaeologist Dennis Jenkins published an article on the coprolitos of an Oregon cave that is over 14,000 years old.

Radiocarbon dating has given fossil lines, and genetic tests reported that they belonged to man. A deeper investigation of the Coprolitos added more evidence that an organization on the west coast 1,000 years before the arrival of the Clovis people.

Located in the center of Oregon-South, the caves seem to be a piece of the puzzle that indicates how humans have the continent thousands of years ago.

The in Alaska with the oldest evidence of human housing is Swan Point, in the region of the central-east of the State. In addition to the 14,000 -year -old teams and homes, gigantic bones were discovered there.

Although Alaska can have a richness of archaeological evidence of the first Americans, it is also a difficult position to dig. “His excavation season is very close and expensive,” Feder said. Some require a helicopter to achieve, for example.

The researchers who examine the site began to realize that the artifacts discovered on the site belonged to other cultures. Clovis’s problems are larger than Folsom flutes, which were first discovered in another archaeological site of New Mexico.

Blackwater Draw Museum of the University of New Mexico in the East of New Mexico provides the archaeological site between April and October.

One of the reasons why the dates of the human profession in North America are so debatable is that very few old remains have been found. Among the oldest, there is a Sun river boy up, or Xaasaa Na ‘, in the middle of Alaska.

Based on the child’s genetic information, the researchers learned that he was connected to fashion asleans, but not directly. His non -unusual ancestors began to remarry genetically 25,000 years before dividing into two teams after a few thousand years: the ancient Berignians and the ancestors of the fashionable Americans.

According to this research, humans would possibly succeed in Alaska about 20,000 years ago.

Pictograms can have a non -secular and practical meaning, but also capture a time when the teams gathered and mixed, according to the Utah Natural History Museum.

More than 900 years ago, the other town of Puebloan built the White House, which bears the name of the shadow of their clay. Its upper floors are sitting in a sandstone cliff, with a transparent fall of the windows.

In the 1860s, the United States government forced 8,000 Navajo to move to Fort Sumner in New Mexico. Fatal adventure is known as the “long walk. ” Finally, they were able to return, their houses and their cultures were destroyed.

In early 1900, two shaped the Leling Association of Coliff Coliff, hoping to maintain the ruins in the state region of the Southwest. A few years later, President Theodore Roosevelt signed an invoice that designates the Green Mesa as the first national park aimed at “maintaining the works of man. “

Tourists can see many of those housing on the road, but some are also available after a walk. Some require more tickets and can be congested, Feder said.

At that time, he is booming with hunters, farmers and artisans. “It’s an agricultural civilization,” Feder said. “It is a position where raw fabrics arrive thousands kilometers away. ” The researchers also discovered articular wells, potentially discovered in human sacrifices.

Although Cahokia is open to the public, the portions are recently closed for renovations.

Presented in a limestone cliff in Camp Verde, Arizona, this is an apartment, not a castle, and is not connected to Sovereign Aztec Montezuma.

“These other people were architects,” he said. “They had a feeling of beauty. “

The population was also practical, discovering irrigation systems and structure techniques, such as thick walls and shaded spots, to help them in the warm and dry climate.
