Since the paper is not open access, let me give you the abstract first: Most Indian groups descend from a mixture of two genetically divergent populations: Ancestral North Indians (ANI) related to Central Asians, Middle Easterners, Caucasians, and Europeans; and Ancestral South Indians (ASI) not closely related to groups outside the subcontinent.

The date of mixture is unknown but has implications for understanding Indian history.

There is a new paper out of the Reich lab, Genetic Evidence for Recent Population Mixture in India, which follows up on their seminal 2009 work, Reconstructing Indian Population History.

There has been a trend over the past few years of scholars in the humanities engaging in deconstruction and intellectual archaeology which overturns old historical orthodoxies, understandings, and leaves the historiography of a particular topic of study in a chaotic mess.

These results show that India experienced a demographic transformation several thousand years ago, from a region in which major population mixture was common to one in which mixture even between closely related groups became rare because of a shift to endogamy.

I want to highlight one aspect which is not in the abstract: the closest population to the “Ancestral North Indians”, those who contributed the West Eurasian component to modern Indian ancestry, seem to be Georgians and other Caucasians.

The shift from widespread mixture to strict endogamy that we document is mirrored in ancient Indian texts.

Dec 11, 2015. Discusses mutation and gene flow leading to variation in populations. packs Figure below, juvenile males may leave the group to find mates and establish separate populations. Human history includes countless migrations; gene flow continues to mix gene pools and cause microevolutionary changes.

Genetic Diversity. Human evolution is driven by a number of different factors, including migration and settlement in different environments, genetic mutation, natural selection. more than 20,000 genes; each gene being a single unit of inheritance that is transmitted. A gene is, as stated above, the basic unit of inheritance.

Some have contended that the migrations mentioned in the Book of Mormon did not occur because the majority of DNA identified to date in modern native peoples most closely resembles that of. These mutations accumulate over time as they are passed from generation to generation, resulting in unique genetic profiles.

Jan 24, 2011. But it is now clear that p53 regulates other key stages of metastatic progression, such as cell migration and invasion. In various cancers, mutations have been found throughout Tp53, the gene that encodes p53. Many of these. The role of p53 in tumour suppression lessons from mouse models. Cell.

Homo sapiens evolved from their early hominid predecessors between 200000 years ago and developed a capacity for language about 50000 years ago.
