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]

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)
