As shown in these ancestry paintings from 23andMe, the proportion of African DNA can vary widely for African Americans.
A recent study led by Carlos Bustamante of Cornell and Sarah Tishkoff of the University of Pennsylvania has shown that genetically speaking, African American can mean a lot of different things.
The researchers and their co-workers analyzed DNA [...]

In our last post we highlighted a few of the coolest (in our opinion!) health-related developments of 2009. But human genetics isn’t all about disease. Here are a few more favorites:
The Romanovs
2009 saw the identification of the remains of the missing members of this Russian royal family, as well as identification of the mutation that [...]

Which is why the members of an international team of genetic anthropologists led by Sarah Tishkoff of the University of [...]

Once distributed throughout tropical Africa, Pygmies now live in pockets of the continent’s rainforest.
Africa is home to a number of dwindling hunter-gatherer populations, most of them living deep in the rainforests that stretch from western Africa’s Atlantic coast to the eastern edge of the Democratic Republic of Congo. Known as “Pygmies” because of their short [...]

This guest post is by Brenna Henn, a doctoral student in Stanford University’s Department of Anthropology and a 23andMe consultant. Brenna studies human evolution using genetic information. Her interests include the origin of modern humans, migration patterns among African groups, and genetic models of demography.
