Indigenous Mexicans migrated to California 5,200 years ago, likely bringing their languages with them, ancient DNA reveals

Hunter-gatherers from Mexico migrated into California more than 5,000 years ago, potentially spreading distinctive languages from the south into the region nearly 1,000 years earlier than previously thought, a new genetic study details.

The finding challenges the idea that what are known as the Uto-Aztecan languages — which include the Aztec and Toltec language Nahuatl, as well as Hopi and Shoshoni — were spread northward by prehistoric migrants from Mexico along with maize farming technologies...

Nakatsuka and his colleagues studied ancient DNA extracted from the teeth and bones of 79 ancient people found at archaeological sites in central and southern California. These remains were dated to between 7,400 and 200 years ago.

They also extracted ancient DNA from the remains of 40 people from sites in the northwest and central north of Mexico, which were dated to between 2,900 and 500 years ago.

By comparing the ancient genomes, the researchers found evidence for increased migration from northern Mexico into southern and central California about 5,200 years ago.

The timing of this migration refutes an existing idea that the spread of maize farming from about 4,300 years ago led to the spread of Uto-Aztecan languages, as migrant farmers prospered more than the hunter-gatherers who lived there before them. But the new study indicates that such languages may have been spread instead by a migration of hunter-gatherers that occurred nearly 1,000 years earlier...

He noted that the remains of many of the individuals analyzed in the study have been curated in museums in the United States and Mexico for many decades. "Now with advances in ancient DNA technology, these individuals are being given a voice through this research to help write their history," Hard said.

Human sacrifice was a common practice among all the peoples of Central and Southern Mexico. The apparent difference with the Mexica/Aztecs was just in the scale of the operation.

That said, we know very little of the scale (or rate) of human sacrifice among the other peoples and states of the region, we just dont have enough information.

In the north there were also cultures that practiced human sacrifice, notably the Iroquois, and I think the Algonquins. And even more that practiced cannibalism.

I cited “Man Corn”, C.Turner, about cannibalism in whats now the US Southwest, affecting the Anasazi (now Hopi, Zuni, etc) people.

Point well taken. They must have had test tube labs in their caves..

"Obsedian from a single 100+ mile offshore source in the med has been found in Neanderthal sites dating past 50000 years closer to 100,000 all over the med. This alone confirms seafaring tech in the Stone age rafts couldn’t make the trip and swimming is right out."

There are deep scouring marks on the floor of the Med just inside Gibralter....this supports the theory that the Med was 'plugged' at Gibralter during the Ice Age and the Med nearly dried out.
When the 'plug' broke a monumental waterfall occurred at Gibraltar and slowly filled the med and eventually crashed through the barriers at the Bosporus flooding (Noah's Flood) that fresh water lake (Black Sea) about 7,600 years ago.

There was a time when people lived on the floor of the Med. and wandered around it for hundreds of miles.

When the Black Sea began to flood, the water rose about one foot per day...people were able to safetly walk away and I expect something similar when the Med refilled...walkaways.

The refugees from the Black Sea flood fled up the river valleys into Europe and took farming and their Indo-European languages with them.

BTW, the Med did completely dry out at least once but it was five million years ago.

Thanks for the reply, I’m a geologist I am familiar with the Mediterranean Sea dry out events. There is geological evidence in the massive salt layers all the events left behind those didn’t wash away they were already covered by additional sediments and persist to this day deep below the seafloor younger sediments. The time periods I am referring to 50000 and 100000 years bp the med had water in it deep waters at that.

There is other evidence of Neanderthal boat technology along with Homo Sapian our first species before we became modern H.Sapiens Sapiens all three species have shown long-distance open ocean crossings making boats is not hard especially skin on driftwood or bone boats, canoes and kayaks or Umiak. People have paddled all of those types across the Atlantic the Pacific and Med. One German paddled from Germany to Australia in a kayak. Launched from Peru a balsa raft built by hand with Stone age tools made it to Polynesian deep into Polynesia. A reed boat built to first Dynasty Egyptian levels crossed the Atlantic to the Caribbean. A Irish explorer took a cowskin and wood boat against the current from Ireland to New York also hand made to Stone age tech levels. Humans have crossed oceans long before writing was invented to document it. We are the third probably fourth species of humans to master ocean going boat technology. Homo Erectus era digs have yielded the tools needed to hollow out logs to make canoes,or catamarans or outrigger type.
