"Scientists have reconstructed the genome of a man who lived 45,000 years ago, by far the oldest genetic record ever obtained from modern humans. The research, published on Wednesday in the journal Nature, provided new clues to the expansion of modern humans from Africa about 60,000 years ago, when they moved into Europe and Asia. And the genome, extracted from a fossil thighbone found in Siberia, added strong support to a provocative hypothesis: Early humans interbred with Neanderthals."
The genome of the Anzick child, who died 12,600 years ago at the age of three and was buried with ceremony in the American Rockies, has been fully sequenced. The results shed an incredible light on the history of the peopling of the Americas: his people seem to have been direct ancestors to most tribes of Central and South America, and close relatives of the Canadian tribes. The discoveries have had an emotional impact on Native Americans, and the boy's remains will be reburied with great respect. Still, tribal belonging is about much more than genetics, as anthropologist Kim Tallbear reminds us. You can see replicas of the heirloom artefacts left in the boy's grave here, or visit the collection at the Montana Historical Society if you're in the area.
A new study suggests that humanity's sense of fair play and kindness towards strangers is determined by culture, not genetics. Speculation: the finding may be directly related to the rise of religion in human history, as well as more complex economies. (Via). [more inside]
How We Evolve: "A growing number of scientists argue that human culture itself has become the foremost agent of biological change, making us — for the past 10,000 years or so — the inadvertent architects of our own future selves." [more inside]
The Etruscan civilization flourished in central Italy around the 6th century BC before the rise of the Roman Empire. Known for high art and high living, some say the Etruscans were influential in molding Roman and western civilization, however it has always been an enigma on where the Etruscans originally came from. DNA evidence has probably solved the mystery, confirming what Greek historian Herodotus first said over 2,500 years ago.
Genes and Jews. And you thought Spock came up with that part of the shtick. It turns out that despite the racial and ethnic diversity of the Tribe, there are genetic markers that identify Cohanim, or the priestly descendants of Aaron (know any Cohens?). These markers help identify jewish identity in the most distant reaches of the diaspora. The fascinating intersection of anthropology, genetics, and religion. (btw first fpp)
