Scientists Unlock Secrets of Ancient Human DNA

In the 1860s, Swiss chemist Friedrich Miescher discovered human DNA. This discovery assisted scientists in uncovering truths about our ancient ancestors. Even in 2018, researchers made new findings. This excavation unearthed various old mysteries, including a hitherto undiscovered group of ancient humans. Read about their discoveries here.
Two Skeletons That Are 11,500 Years Old
In 2018, archaeologists discovered the skeletons of two Native American infants. They were both 11,500 years old and members of the same family. These were not regular skeletons. They were well-preserved enough to help scientists understand early humanity. In fact, they include information about the first humans to visit North America.

Researchers Visited a Remote Alaskan Location
In the early 2000s, anthropology professor Ben Potter started working in Upward Sun River, Alaska. This forested location is 50 miles from Fairbanks and only accessible by helicopter. Despite the rough terrain, Potter had a valid cause for excavating there. That area of Alaska was once connected to Europe and Africa.

What Is Beringia?
When Pangea began to disintegrate, several land corridors remained between the continents. The earliest known humans were born in Africa, but they spread around the world. Beringia served as a bridge between Siberia and Alaska. Many archaeologists believe that the first North American inhabitants crossed that bridge around 34,000 years ago. However, this was only a theory.
What Is Beringia
The Beringian Standstill Hypothesis
Many historians assume that early humans reached Beringia, although they don’t know who accomplished it. One proposal, known as the Beringian standstill hypothesis, attempts to address this. According to the concept, the “Ancient Beringians” lived alone on Beringia due to the ice and hard environment. If this is accurate, archeologist Jennifer Raff believes the Beringians are the sole forefathers of all Native Americans.

Native Americans still reside close to the Upward Sun River, in fact.
The name “Upward Sun River” is a translation of the Athabascan language, Xaasaa Na’, which is still spoken by Native Americans in Alaska. It’s also part of their area. Potter interacted with Native Americans during his excavations. They are typically fiercely protective of their burial grounds; nonetheless, they recognized the value of Potter’s work and offered to assist him.

The First Discovery: A Three-Year-Old Child
In 2010, Potter and other University of Alaska scholars investigated the Upward Sun River. They found the cremated remains of a three-year-old child. At 11,500 years old, this discovery was extremely rare. Unfortunately, the skeleton was not sufficiently preserved to extract DNA from. Scientists could not even determine the gender.

Despite The Letdown, Potter Didn’t Give Up
Despite their modest success, Potter and his colleagues refused to give up. They continued excavating in that area for another eight years. Potter and his colleagues, José Víctor Moreno Mayar and Lasse Vinner, got their big break. They discovered an approximately 15,000-year-old burial site in Alaska.

At last, they discovered the skeletons of two babies
Potter and his team unearthed two newborn skeletons. One appeared to be stillborn, while the other was between six and twelve weeks old. The two, like the three-year-old, appeared to have been incinerated, with their ashes resting on a fire pit. However, these remains were better kept and easier to identify.

The Burial Ground Was Well-Preserved
The two infants were buried behind several things and covered in red ochre. This ochre, which was most likely used at the funeral, helped to preserve the skeletons. The babies were also buried under a mixture of sand and soil. This high-acid mixture is great for preservation. Clearly, the individuals who buried them loved them very much.

Who Were The Two Girls?
DNA tests confirmed that both infants were female and related, likely first cousins. The stillborn died at 30 weeks gestation, having never had the opportunity to live. The local Native community dubbed the girls “Xach’itee’aanenh T’eede Gaay” (Sunrise Girl-Child) and “Yełkaanenh T’eede Gaay” (Dawn Twilight Girl-Child).

There were other items in the grave as well
This burial was obviously important to the mourners. Archaeologists found several more objects in the burial, including antlers and spear points. The two girls were buried together in a joint funeral. However, Sunrise Girl (the six-week-old newborn) appeared to be better maintained and provided the foundation for the majority of the DNA results.

What, Exactly, Were The Researchers Studying?
To investigate the DNA, geneticists had to delve into the mitochondria. Science students remember mitochondria as “the powerhouse of the cell” because cells die without them. Every cell in the body has DNA, and the mitochondria power the cells. As a result, the scientists require healthy cells to examine—which is easier said than done.

Here’s Why They Couldn’t Study The Three-Year-Old
Old bones are not guaranteed to contain living cells. If scientists want to investigate DNA, they need a bone that is thick enough and well kept. Researchers usually test the petrous bone, which is located at the base of the skull. Because the three-year-old’s bones were too destroyed, researchers were unable to examine the DNA. However, with the two infants, they could.

What Came From The DNA Tests?
Sunrise Girl’s ethnicity was confirmed by the first wave of DNA tests conducted at the University of Alaska. According to the findings, she was closely related to Native Americans, but in a unique way. Scientists believe her DNA is significantly older than any previously analyzed remains. In other words, she represents a hitherto unknown genetic community of Native Americans.

They Revealed A New Ancient Human
This previously undiscovered DNA, identified as USR1, dates back at least 20,000 years and possibly up to 34,000 years. According to Eske Willerslev, a professor at the University of Copenhagen and co-author of the study, they are the oldest known Native Americans. “It changes our understanding of the timing of events that formed the genetics of Native Americans,” Willerslev told CNN Health.

They may be Beringians from ancient times
Sunrise Girl’s DNA supports the Beringian standstill concept. Scientists believe she could be an Ancient Beringian, something specialists have only speculated about previously. “We think the explanation for this pattern, the one that requires the least movement, was that Native Americans were somewhere in Beringia 20,000 years ago,” noted Victor Moreno Mayar, another research author.

But The Two Girls Had Different DNA
The initial DNA study was performed on the six-week-old’s skull. Geneticists predicted that the second infant will have comparable DNA. But, unexpectedly, she didn’t. Dawn Twilight Girl, the stillborn, was investigated at the University of Copenhagen in Denmark. She had a completely different maternal ancestry than her first cousin, and the two were not linked.
