Native South American tribes were found to have evidence of ancient Australian DNA

The first humans to cross the Bering Strait some 15,000 years ago had indigenous Australian DNA that is now found in the bloodlines of South American tribes, research shows.

  • Previous work found ancient Australian DNA in modern Amazons
  • However, a new study finds that the ancestral DN runs deeper in South America
  • A genetic analysis found that tribes along the Pacific coast have the DNA
  • Ancient Australians migrated to Asia, where they integrated with humans
  • Those people traveled across the Bering Strait Land Bridge to North America
  • Experts believe they were trapped along the Pacific coast when they moved to South America
  • This explains why ancient Australian DNA is not found in North American natives

Australia is considered the most isolated continent on Earth, but DNA from early indigenous groups spread around the world and specifically in the ancient bloodline of South American tribes.

Earlier work from 2015 first revealed a link between ancient Australians and Amazon groups, but a new study finds it goes even deeper than previously believed.

A genomic analysis of individuals from a number of indigenous South American groups revealed features of Australasian influence in Peru and Brazil, and showed that it was first introduced via the Pacific coastal route before the formation of the Amazon branch.

While the findings may provide a miraculous story of ancient Australians crossing the Pacific in boats to South America, the new genetic model shows no evidence of an expedition – instead, they walked.

Researchers state that the ancestors come from early Australians who integrated with the first Americans who made the long journey from Asia across the Bering Strait land bridge some 15,000 years ago.

The genetic analysis also showed that these individuals clung to the Pacific coast during their travels through North America, which may explain why native Americans in the US do not have the genetic markers.

Researchers argue that the lineage stems from early Australians who integrated with the first Americans who made the long journey from Asia across the Bering Strait land bridge some 15,000 years ago.

The Bering Strait Land Bridge, also known as Beringia, was formed towards the end of the Ice Age when sea levels began to drop and slowly exposed the flat, grassy land below.

The country connected Asia to North America, stretched for thousands of miles from north to south, and became an essential transportation path between Asia and North America.

The new study proposes that this now-vanished landmass has resulted in South Americans having Australian DNA.

The team built this study on a previous researcher who discovered the genetic component of the Australasian population ‘Ypikuéra population’ or ‘Y population’ exclusively among the current Amazon populations.

Researchers collected genomic data from 383 individuals, resulting in 438,443 markers, from various South American native tribes.

After the analysis, the team found that the Y signal occurs not only in Amazonian groups, but also in the indigenous peoples of Chotuna (living near the Pacific coast of Peru), Guaraní Kaiowá (central western Brazil) and Xavánte (close to the center of Brazil).

Our results showed that the Australasian genetic signal, previously described as exclusive to Amazonian groups, was also identified in the Pacific coastal population, indicating a more widespread signal distribution within South America, and possibly implying an ancient Pacific-Amazon contact. residents, ” the researchers, led by lead author and evolutionary biologist Marcos Araújo Castro e Silva of the University of São Paulo (USP) in Brazil, explain in their study published in PNAS

The findings also revealed that in South America there were at least two waves of migration of ancient people with Australasian genetic DNA.

The first wave settled in the coastal areas of the Pacific Ocean, and the next moved eastward to the Amazon and central Brazil.

The study also acknowledges why Australasian genetic DNA has not been found in Native American bloodlines.

This genetic evidence for the presence of Y ancestors on the South American Pacific coast indicates that these ancestors probably reached this region via the Pacific Coastal Route and therefore the absence of this genetic component in the populations of North and North America studied so far. Can explain Central America. ‘says the study.

WHEN DO PEOPLE ARRIVE IN NORTH AMERICA?

It is generally accepted that the first settlers crossed from what is now Russia to Alaska via an old land bridge over the Bering Strait, which was submerged at the end of the last Ice Age.

Issues such as whether there was one founding group or several when they arrived, and what happened next, have been the subject of extensive discussion.

The earliest evidence of human settlers on the continent dates back to about 14,000 years ago, with the remains of an ancient village found ‘older than Egyptian pyramids’ in April 2017.

Artifacts discovered in the settlement, found on Triquet Island 310 miles (500 km) northwest of Victoria, Canada, include tools for making fires and fishing hooks and spears from the Ice Age.

Recently, researchers found human footprints found off the coast of the Pacific Ocean in Canada.

They show that at the end of the most recent Ice Age, people lived 13,000 years old.

The footprints, which are the only ever found around Canada’s Pacific coast during this time, are from at least three different individuals.

The incredible prints could have captured the moment these individuals first stepped off the craft before heading to drier areas.

Digital photo analysis revealed that the footprints probably belonged to two adults and a child, all barefoot.
