Archaeological Find: Humans may have been in North America 30,000 years ago

Stunning Cave Discovery Just Changed The Timeline of Human Presence in North America
LINK
Tools excavated from a cave in central Mexico are strong evidence that humans were living in North America at least 30,000 years ago, some 15,000 years earlier than previously thought, scientists said Wednesday.?
Artefacts, including 1,900 stone tools, showed human occupation of the high-altitude Chiquihuite Cave over a roughly 20,000 year period, they reported in two studies, published in Nature.
"Our results provide new evidence for the antiquity of humans in the Americas," Ciprian Ardelean, an archeologist at the Universidad Autonoma de Zacatecas and lead author of one of the studies, told AFP.
"There are only a few artefacts and a couple of dates from that range," he said, referring to radiocarbon dating results putting the oldest samples at 33,000 to 31,000 years ago.
"However, the presence is there."
No traces of human bones or DNA were found at the site.
"It is likely that humans used this site on a relatively constant basis, perhaps in recurrent seasonal episodes part of larger migratory cycles," the study concluded.
The stone tools – unique in the Americas – revealed a "mature technology" which the authors speculate was brought in from elsewhere.

Archaeological evidence – including uniquely crafted spear points used to slay mammoths and other prehistoric megafauna – suggested this founding population, known as Clovis culture, spread across North America, giving rise to distinct native American populations.
But the so-called Clovis-first model has fallen apart over the last two decades with the discovery of several ancient human settlements dating back two or three thousand years earlier.
Moreover, the tool and weapon remnants at these sites were not the same, showing distinct origins.
"Clearly, people were in the Americas long before the development of Clovis technology in North America," said Gruhn, an anthropology professor emerita at the University of Alberta, commenting on the new findings.
In a second study, Lorena Becerra-Valdivia and Thomas Higham, researchers at the University of Oxford's Radiocarbon Accelerator Unit, used radiocarbon – backed up by another technique based on luminescence – to date samples from 42 sites across North America.
Using a statistical model, they showed widespread human presence "before, during and immediately after the Last Glacial Maximum" (LGM), which lasted from 27,000 to 19,000 years ago.

Human populations scattered across the continent during an earlier period also coincide with the disappearance of once-abundant megafauna, including mammoths and extinct species of camels and horses.
"Our analysis suggests that the widespread expansion of humans through North America was a key factor in the extinction of large terrestrial mammals," the second study concluded.
Many key questions remain unanswered, including whether the first of our species to wander across the frozen tundra of Beringia made their way south via an interior route or – as recent research suggests – by moving along the coast, either on foot or in boats of some kind.

so in 29,500 +/- year those in north America only progressed to the level of civilization of 1500's native Americans? with all of north america's natural resources?

We so worried about black people and sometimes forget about the Clovis’s people. Gone but not forgotten

Christianity gave birth to modern science so I'd guess that would be a huge factor

They’ve recently found evidence Polynesians were in South America long ago. Makes me wonder where these people came from Asia or somewhere else?

No, there is evidence (don't ask me to link it, my college professor told me so) that the natives actually had mastered combustion and were working on laser guns before the white man invaded and stole it for himself.

The book Guns Germs & Steel has some thoughts on that.
Agriculture arose in Mesoamerica and China. Due to environmental qualities like soil fertility, availability of domesticable animals, and availability of edible crops, however, it took a longer time for agriculture to supplant hunter-gatherer culture in most other regions. Once agriculture had arisen around the world, it spread or diffused to neighboring regions. By and large, Diamond argues, it is easier for ideas, goods, and foods to spread from east to west than it is for them to spread north and south—this is because the Earth spins east-west, meaning that areas with the same latitude share a similar climate and environment. Archaeological data indicates that agricultural innovations diffused east and west far sooner than they diffused north and south.

30000 years ago was still at the end of an ice age. the glaciers were still present over much of the area now known as the united states

Hard to believe in 30K years that some MFer couldn't have invented the damn wheel.

I’m supposed to be stunned that scientists were completely wrong?
