11,500-Year-Old Skeleton Reveals an Unknown Group of Ancient Migrants to the Americas

In 2013, deep in the forest of central Alaska's remote Tanana River Valley, archaeologists unearthed the remains of a 6-week-old baby at a Late Pleistocene archaeological site. The tiny bones yielded big surprises for researchers, who announced this week that the child's genome—the oldest complete genetic profile of a New World human—reveals the existence of a human lineage that was previously unknown to scientists. Related to yet genetically distinct from modern Native Americans, the infant offers fresh insights into how the Americas were first peopled, National Geographic reports.

Published in the journal Nature on January 3, the study analyzed the DNA of the infant, whom the local Indigenous community named Xach'itee'aanenh T'eede Gaay ("sunrise girl-child" in the local Athabascan language). Then, researchers used genetic analysis and demographic modeling to identify connections between different groups of ancient Americans. This allowed them to figure out where this newly identified population—named Ancient Beringians—fit on the timeline.

The study suggests that a single founding group of Native Americans separated from East Asians some 35,000 years ago. This group, in turn, ended up dividing into two distinct sub-groups 15,000 years later, consisting of both the Ancient Beringians and what would eventually become the distant ancestors of all other Native Americans. The division could have occurred either before or after humans crossed over the Bering land bridge around 15,700 years ago.

After arriving in the New World, Ancient Beringians likely remained north, while the other population spread out across the continent. Eventually, the Ancient Beringians either melded with or were replaced by the Athabascan peoples of interior Alaska. 

The study provides "the first direct evidence of the initial founding Native American population, which sheds new light on how these early populations were migrating and settling throughout North America," said Ben Potter, the University of Alaska-Fairbanks archaeologist who discovered the remains, in a news release. Potter was a lead author of the study, along with Eske Willerslev and other researchers at the Center for GeoGenetics at the University of Copenhagen's Natural History Museum of Denmark.

People Have Been Dining on Caviar Since the Stone Age

Millennia before caviar became a staple hors d'oeuvre at posh parties, it was eaten from clay pots by Stone Age humans. That's the takeaway of a new study published in the journal PLOS One. As Smithsonian reports, traces of cooked fish roe recovered from an archeological site in Germany show just how far back the history of the dish goes.

For the study, researchers from Germany conducted a protein analysis of charred food remains caked to the shards of an Stone Age clay cooking vessel. After isolating roughly 300 proteins and comparing them to that of boiled fresh fish roe and tissue, they were able to the identify the food scraps as carp roe, or eggs. The scientists write that the 4000 BCE-era hunter-gatherers likely cooked the fish roe in a pot of water or fish broth heated by embers, and covered the pot with leaves to contain the heat or add additional flavor.

The clay shards were recovered from Friesack 4 in Brandenburg, Germany, a Stone Age archaeological site that has revealed about 150,000 artifacts, including items crafted from antlers, wood, and bone, since it was discovered in the 1930s. In the same study, the researchers report that they also found remnants of bone-in pork on a vessel recovered from the same site.

Other archaeological digs have shown that some of the foods we think of as modern delicacies have been around for thousands of years, including cheese, salad dressing, and bone broth. The same goes for beverages: Recently a 13,000-year-old brewery was uncovered in the Middle East.

Dozens of Cat Mummies, Plus 100 Cat Statues, Discovered in 4500-Year-Old Egyptian Tomb

The mummification of cats was a common practice in ancient Egypt, but it’s always a pleasant surprise when the felines are found thousands of years later. As NPR reports, dozens of mummified cats and 100 wooden cat statues were recently discovered in a 4500-year-old tomb near Cairo.

These items were uncovered by Egyptian archaeologists while excavating a newly discovered tomb in Saqqara, whose necropolis served the ancient city of Memphis. Another nearby tomb remains sealed, and it’s possible that it may have evaded looters and remained untouched for millennia.

In addition to the wooden statues, one bronze cat statue was found. It was dedicated to Bastet, goddess of cats, who was said to be the daughter of Re, god of the Sun. While cats were revered by ancient Egyptians, they weren’t directly worshipped. Rather, gods like Bastet were often depicted with the physical characteristics of an animal that was considered divine.

Even rarer than the mummified cats were a couple collections of mummified scarab beetles that were found in the tomb—the first of their kind to be unearthed in this particular necropolis, Egypt's Ministry of Antiquities announced in a Facebook post. The scarabs were still in “very good condition” because they had been wrapped in linen and placed inside two limestone sarcophagi, whose lids had black scarabs painted on top.

"The (mummified) scarab is something really unique. It is something really a bit rare," Mostafa Waziri, secretary general of Egypt's Supreme Council of Antiquities, told Reuters and other media. "A couple of days ago, when we discovered those coffins, they were sealed coffins with drawings of scarabs. I never heard about them before."

The beetles were an important religious symbol in ancient Egypt, representing renewal and rebirth. The Ministry of Antiquities said archaeologists also found wooden statues of a lion, a cow, and a falcon, as well as painted wooden sarcophagi of cobras (with mummies inside) and wooden sarcophagi of crocodiles.
