DNA harvested from the remains of an infant buried 13,000 years ago confirms that the earliest widespread culture in North America was descended from humans who crossed over to the New World from Asia, scientists say. <\/p>\n
The research, detailed in this week's issue of the journal Nature, also suggests that many contemporary Native Americans are direct descendants of the so-called Clovis people, whose distinctive stone tools have been found scattered across North America and Mexico. <\/p>\n
The origins and genetic legacy of the people who made Clovis tools have been topics of debate among scientists. While most archaeologists think that the Clovis people were descended from Asians, an alternative theory suggests that the Clovis ancestors emigrated from southwestern Europe during the Last Glacial Maximum more than 15,000 years ago. <\/p>\n
The new findings strongly refute that idea, known as the Solutrean hypothesis, said study co-author Michael Waters, director of the Center for the Study of the First Americans at Texas A&M University. \"This shows very clearly that the ancestry of the very first Americans can be traced back to Asia,\" Waters said. <\/p>\n
David Anderson, an anthropologist at the University of Tennessee Knoxville, agreed. \"There's been a standard model for a long time that modern Native Americans are descended from populations coming from East Asia a few thousand years before Clovis, and that's what this finding reinforces,\" said Anderson, who was not involved in the study. <\/p>\n
Anthropologist Dennis Jenkins of the University of Oregon said the new study was a \"really important and really well done piece of research\" that opens the door for new kinds of genetic comparisons among ancient Native American remains. <\/p>\n
\"The importance of this cannot be overemphasized,\" said Jenkins, who also did not participate in the research. <\/p>\n
\"People have often asked me what's the relationship of the Paisley Caves\"a site in Oregon where human feces and artifacts up to 13,200 years old have been found\"to Clovis, and I've always said that would be really nice to know, but there hasn't been any Clovis DNA until now,\" he said. <\/p>\n
Oldest Burial in North America <\/p>\n
The skeleton of the Clovis childwhich experts determined belonged to a young boy about one to one-and-a-half years oldwas discovered in 1968 in the Anzick burial site in western Montana. Dozens of ochre-covered stone tools found at the site were consistent with Clovis technology, and radiocarbon dating revealed that the skeleton was approximately 12,600 years old. <\/p>\n
