DNA from fossils found in southern China suggests Native Americans have East Asian roots

DNA from 14,000-year-old fossils found in southern China suggests Native Americans have East Asian roots.

  • Fossils found in China demonstrate that Native Americans may have had genetic roots in East Asia.
  • The data will help us understand “how people change their appearance, adapting to local conditions over time,” says study co-author Bing Su.

DNA from ancient fossils in the south China showed that Native Americans may have roots in the East Asia.

The scientists compared the genetic information of late Pleistocene fossils with information about people around the world.

They found that the bones belonged to a person who was closely related to the East Asian roots of the Native Americans.

Archaeologists have succeeded in sequencing the genome of fossils.

Researchers have successfully sequenced the genome of Late Pleistocene fossils for the first time. The image above is a side view of a skull found in the Red Deer Cave.

“The ancient DNA technique is a really powerful tool,” says Bing Su, co-author of the study at the Chinese Academy of Sciences.

“This tells us quite definitely that the Red Deer Cave people were modern humans and not archaic species like Neanderthals or Denisovans, despite their unusual morphological features.”

They suggested that some southern East Asians traveled north along the coast of present-day China through Japan and eventually reached Siberia.

It is believed that they then crossed the Bering Strait between Asia and North America and became the first people to arrive in the New World.

The work that led to these discoveries began over thirty years ago.

At that time, a team of archaeologists in China discovered a large set of bones at Maludun, or Red Deer Cave, in Yunnan Province in southern China.

Archaeologists have used carbon dating, which uses the relative proportions of the carbon isotopes carbon-12 and carbon-14 to age organic matter, to show that the fossils date back to the late Pleistocene about 14,000 years ago.

The discovery dates back to work that began decades ago when archaeologists found a large set of bones at Maludong, or Red Deer Cave, pictured above.

This was a period of time when modern humans migrated to many parts of the world.

The researchers recovered from the cave a hominin cranial cap that had features of both modern and archaic humans.

For example, the shape of the skull resembled the skull of a Neanderthal, and his brain turned out to be smaller than that of a modern person.

As a result, some anthropologists believed that the skull probably belonged to an unknown archaic human species that lived until recently, or a hybrid population of archaic and modern humans.

The discovery contributes to our understanding of the rich genetic diversity of the hominins that lived at that time in southern East Asia.

Su says this suggests that the early people who first arrived in East Asia first settled in the south before some moved north.

“This is important evidence for understanding early human migration,” he explains.

“Such data will not only help us paint a more complete picture of how our ancestors migrated, but also provide important information about how people change their appearance to adapt to local conditions over time, such as changes in skin color in response to changes in in appearance.” exposure to sunlight, Su says.

The team’s findings were published on July 14 in the journal Current biology.

DNA: A COMPLEX CHEMICAL SUBSTANCE CARRYING GENETIC INFORMATION IN PRACTICALLY ALL BODIES

DNA, or deoxyribonucleic acid, is a complex chemical in almost all organisms that carries genetic information.

It is located on the chromosomes of the cell nucleus, and almost every cell in the human body has the same DNA.

It consists of four chemical bases: adenine (A), guanine (G), cytosine (C) and thymine (T).

The DNA double helix structure comes from the binding of adenine to thymine and the binding of cytosine to guanine.

Human DNA consists of three billion bases, and more than 99 percent of them are the same in all people.

The order of the bases determines what information is available to support the organism (similar to how the letters of the alphabet form sentences).

The bases of DNA are connected to each other, and also attached to a sugar molecule and a phosphate molecule, forming a nucleotide.

These nucleotides are arranged in two long strands forming a helix called a double helix.

The double helix looks like a ladder, with the base pairs forming the rungs and the sugar and phosphate molecules forming the vertical side pieces.

Recently, a new form of DNA was discovered inside living human cells for the first time.

This shape, called the i-motif, looks more like the twisted “knot” of DNA than the well-known double helix.

It’s unclear what the i-motif’s function is, but experts believe it could be designed to “read” DNA sequences and convert them into useful substances.
