found traces of older Americans


Artefactos de los primeros americanos

Artifacts of Texas site, called Debra L Friedkin, are made of flint and are small, suggesting to researchers that they would be prepared to take with lightweight tools from one place to another comfortably, a kind of campaign team. The site is near stream that has water all year round and a place where there is abundant flint, and it would be a good place chosen by a group of prehistoric people to manufacture the tools they need.
The vast majority of the 15,528 pieces of stone flakes are recovered and studied, which is to make hitting the stone tools in the points needed to tease out a cutting edge. But there are a dozen bifaces and some cutters, a total of fifty finished artifacts. Serve to work on bone, wood or ivory and skins for cutting or processing.

"In Debra L Friedkin found evidences early human occupation 2,500 years before the Clovis people, making the site in the oldest archaeological site in Texas credible and North America, and is important in the debate about the timing of the colonization of America and the origins of Clovis, "said Michael R. Water (University of Texas A & M), team leader of the discoverer, who has worked in this field since 2006.

The new pieces, dated between 13,200 and 15,500 years have appeared in the reservoir level below the known remains of Clovis, and specialists, studying each other, claim that the latter developed techniques of the first conferring characteristics to their tools and weapons. This cultural evolution would solve one problem of the thesis has been defending the American pioneers clovis, and who have not found those specific technological features in Northeast Asia, making it difficult to associate human culture to travel through this territory. In the light of new findings, these tools would be an evolution Clovis those which were manufactured in America.

recalled in Science Researchers already have found some traces preclovis in several places, but they were too few to establish conclusions.

hand axes a million years ago in India
a reservoir in South India that has been explored intermittently since 1863, have now been found stone tools of the Acheulean technological style of doing, at least a million years. Are 70 hand-axes and another 3,500 artifacts such Acheulean quartzite which originated in Africa about a million and a half years and spread throughout Eurasia. The discovery, presented in the journal Science helps us to understand migration patterns of ancient humans from southern Asia and Indonesia. Attirampakkam The site is called, is in Tamil Nadu and was discovered by the British geologist Bruce Foote.
