Humans in North America 30,000 yrs ago - Who Knew?

Big Archaeology Find
An incredibly fascinating archaeology discovery. In a cave in Mexico, archaeologists have found human made stone tools dating back at least 30,000 years. The scientists found the tools in the massive Chiquihuite Cave in northwestern Mexico. Two, separate, new archaeological studies date humans living on the North American continent at least 30,000 years ago. The lead researcher and director of the excavation in the Chiquihuite Cave is Ciprian Ardelean, an archaeologist at the Autonomous University of Zacatecas.
Last Glacial Maximum
The discovery means humans were here before the Last Glacial Maximum when ice covered most of the northern US and Canada. The findings prove that humans were in North America much earlier than previously thought. In fact, at least 17,000 years earlier than believed.
Several New Archaeology Discoveries and Studies
One new study has dated human-made stone tools in North America at 31,500 years old. Another important finding is that humans dispersed across North America 33,000 years ago. And yet another archaeology study, incorporating information from 42 archaeology sites in North America and data from Beringia (the historic region that connected Russia and America) found a human presence 26,000 years ago. The studies were published today in the journal Nature. Their work has changed previous estimates that human arrived in North America 13,000 years ago.
