Brian Handwerk, of National Geographic, has written an interesting and informative article about the genome sequencing of "a 24,000 year old Siberian youth" and its implications on the debate of Native American identities.
"The study authors believe the new study could also help resolve some long-standing puzzles on the peopling of the New World, which include genetic oddities and archaeological inconsistencies...
"These results were a great surprise to us," said study co-author and ancient-DNA specialist Eske Willerslev, of the University of Copenhagen, Denmark.
"I hadn't expected anything like this. A genome related to present-day western Eurasian populations and modern Native Americans as well was really puzzling in the beginning. How could this happen?"...
The arm bone of a three-year-old boy from the Mal'ta site near the shores of Lake Baikal in south-central Siberia (map) yielded what may be the oldest genome of modern humans ever sequenced... "

Ed Yong, of Nature Magazine, has written a thought-provoking article about the implications of the genome of a 24,000 year old Mal'ta boy in solving some of the puzzles in the New World's genetic heritage which has been republished by Scientific American.
"While some of the New World's native ancestry clearly traces back to east Asia, the Mal’ta boy’s genome — the oldest known of any modern human — shows that up to one-third of that ancestry can be traced back to Europe.
The results show that people related to western Eurasians had spread further east than anyone had suspected, and lived in Siberia during the coldest parts of the last Ice Age."
