Archaeologists in Mexico found stone tools and other signs that people were living in North America 30,000 years ago, much earlier than widely believed, according to new research reshaping the debate over the origins of people in the Americas.
In a study reported Wednesday, scientists led by archaeologist Ciprian Ardelean at Mexicos University of Zacatecas said that they had unearthed hundreds of unusual green limestone spear points, blades and other implements from a lofty cavern in the central Mexican highlands. For wandering hunter-gatherers, the cave served as a makeshift tool shed possibly beginning as early as about 33,000 years ago, the scientists said.
These new finds at Chiquihuite Cave, located almost 9,000 feet above sea level and about 400 miles northwest of Mexico City, are the latest in a series of discoveries across North and South America that have archaeologists pushing humankinds entrance into the Americas deeper into antiquity. The discoveries in Mexico were published in the journal Nature.
It is a fundamental change in our way of thinking, said anthropologist Ruth Gruhn, an emeritus professor at the University of Alberta who helped pioneer studies of early migrations into North and South America. She wasnt involved in the find. Dates of around 30,000 years ago indicate that people have been on both continents twice as long as generally believed.

I was thinking can you derive the date civilization began in Mesopotamia mathematically? Start with the latest year we have consistent population data, so for example 1899, then account for death rates and birth rates, and track backwards until we get the first tribe of humans? Or is that far too complex?
The original South Americans were Australoid, i.e., Australian Aborigines.
The fact is, we were much closer together genetically, 30-40,000 years ago than today. I think the DNA proves that.
Also, as the last of the maximum glaciation bore down on the North, people were forced or herded if you will, South of the Himalayas or up through the ice-free long grass tundra of the steppes. Prime mammoth lands which could take you very far over time. That's what they say led to the Amerindians.
Those Southern route people became the Australiods, and the North Asian or Eurasian people gave rise to the Caucasiods, Mongoloids and the non-specialized Mongoloids who would become Amerindians. So genetically, they were just two big gene pools for a while.
Did the Australiods, coming up the coast from Southeast Asia become the remnants that gave rise to the Japanese Ainu, yet could have had a continued Northward drift which would also take them to Berengia, and then on to the Americas, to merge again with the Northern Mammoth hunters who became the non-specialized Mongoloids?
