Sentences with phrase «for lactase persistence»

The selection for lactase persistence in humans happened at least four times, once in Europe and three times in Africa (Tishkoff et al., Nature Genetics 2007 Jan; 39 (1): 31 - 40), and the timing is remarkably correlated with adoption of pastoralism in those parts of the world.

The strongest signal of selection is at the allele responsible for lactase persistence, supporting the view that an appreciable frequency of lactase persistence in Europe only dates to the past four thousand years.

Not exact matches

Some scientific problems with modern paleo movement include: 1) dogmatic insistence on the Raymond Dart model of «man the hunter», which has been contested and supplanted in paleoanthropology for decades; 2) ignorance about the speed of evolutionary adaptation, for example our very recent acquisition of lactase persistence and high amylase gene number; 3) focus on the diets of 80 - 10,000 years ago, dismissing the 40 million years when our lineage were predominantly herbivorous forest dwellers.

For instance, lactase persistence, or the ability to digest lactose into adulthood, is one of those changes that have happened within the last 8000 years.
