How cultural traditions have shaped, and continue to shape, our genomes with presentations on Genomic Basis for Dietary Shifts during Human Origins (Gregory Wray), Adaptations to Human Adult Milk Intake (Sarah Tishkoff), and A Nutritional Basis for the Spread of Indo-European Languages (Henry Harpending) Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [6/2012] [Science] [Show ID: 23904]
Indo-European languages are native to populations from Ireland to Afghanistan and India and, in historical times, to the Tarim Basin in China. This spread occurred within a few thousand years carried by people who were mostly horse pastoralists and who carried a mutant regulator of the lactase gene so that they could as adults digest milk sugar. Individuals with such lactase persistence are able to extract 40% more calories from milk, while others usually ferment away the milk sugar lactose by making cheese or yogurt. While superior technology of invaders can be adapted by indigenous people, such a biological advantage cannot be copied.

Today there is an abundance of DNA sequence data from the entire genome of contemporary human populations, as well as from ancient DNA recovered from extinct forms of humans. Michael Hammer (Univ of Arizona) discusses how analyses of these data, with increasingly sophisticated computational tools, are yielding new insights into human evolutionary history.
