  bet365 ohio promo code newspaper comprehensively reports from foreign media A message released on the official website of the University of Exeter in the UK on July 23,An archaeological research team recently discovered ancient human ruins in a cave in the mountains of northern Mexico,The site dates back to 30,000 bet365 ohio promo code,This is the earliest known record of human activity in the Americas。

Researchers unearthed nearly 2,000 stone tools and some fragments in this cave called Chiquiut,And conducted DNA testing on animal and plant remains in the sediments near the stone tools。The test results indicate,The remains of these animals and plants are about 30,000-2 bet365 ohio promo code50,000 years。Researchers infer this,The earliest time humans were active in this cave may be 30,000 bet365 ohio promo code。This inference challenges the theory generally accepted by the academic community,That is, the Clovis people were 1.The first humans to live in the Americas 50,000 bet365 ohio promo code。

Project leader、Eske Willerslev, professor at St. John’s College, University of Cambridge, UK said,Academic circles have been discussing the time when the first humans entered the Americas。Chiquiut Cave will generate more discussion,Because it is the first location to date humans to the American continent as approximately 30,000 bet365 ohio promo code,Earlier than the previously recognized time1.50,000 years。But the humans who arrived in the Americas 30,000 bet365 ohio promo code did not continue to live in caves,Just use the cave as a temporary residence in winter and summer,Or as a temporary base for hunting during migration。

Project leader、Ciprian Ardelean, a scholar at the University of Zacatecas, Mexico, said,It was once believed that the indigenous peoples of today's America are direct descendants of the earliest Americans,But that doesn’t seem to be the case now。Research Proven,It has long been recognized as the time when humans appeared bet365 ohio promo code,Not the actual earliest time,It is a period of large-scale population reproduction in prehistoric America。(bet365 ohio promo code/Compiler)
