A recent comparison of medieval mitochondrial DNA from a Byzantine cemetery with modern populations in Southwest Turkey shows what we have assumed in our population analyses of atDNA 2.0.
Two reports in the European Journal of Human Genetics underline how specific autosomal DNA can be in revealing the geographical structure among populations. One uses genome-wide data from the Illumina Human Hap300 project to predict the village of origin of a person’s four grandparents given European origins. The other used genotyping from 3,367 individuals from seven different European, mostly British Isles populations to lay bare the detailed population structure and linkage disequilibrium patterns of Ireland, England, Scotland and Wales.

In a paper to be delivered at the American Marketing Association‘s meeting in Washington in June, Elizabeth C. Hirschman estimates that the number of people who have purchased a DNA test now exceeds 1.5 million. Her work suggests that the value of the market (excluding paternity testing) in 2011 will reach nearly $150 million in sales. That seems like too big an industry to escape government oversight, and it’s true that several scientists have targeted the direct-to-the-consumer DNA testing business for criticism, particularly personal genomics companies like 23andme.

The Golden Age of Human Population Genetics
By Molly Przeworski
The timing of the dispersal of anatomically modern humans (AMH) out of Africa is a fundamental question in human evolutionary studies. Existing data suggest a rapid coastal exodus via the Indian Ocean rim around 60,000 years ago. We present evidence from Jebel Faya, United Arab Emirates, demonstrating human presence in eastern Arabia during the last interglacial. The tool kit found at Jebel Faya has affinities to the late Middle Stone Age in northeast Africa, indicating that technological innovation was not necessary to facilitate migration into Arabia.
Emergence petroglyphs as featured on previous blog posts about the Hopi, Sea Peoples, Hohokam, Fremont Indians and Cherokee (“Haplogroup B and Water Clan Symbols”) have also turned up now in Patagonia in southern Chile, on the tip of the South American continent’s Pacific Coast. They were identified in Hawaii already.

Native Hawaiians and Native Americans. Part One
In a previous post, “On the Trail of Spider Woman,” we suggested that petroglyphs in Arizona and Utah with female goddess symbolism and birthing ceremonies were connected with the Hohokam (“Sea Peoples”) and other Indians who followed in their wake, corresponding to archeology and anthropology’s Basketmaker Culture.
