ABSTRACT We present genetic evidence of multiple demographic changes in Armenia and western Iran over the past 7000 years. By about 3000 years ago descendants of the 7000-year-old Chalcolithic Zagrosian herders, hereinafter referred to as Iran-CHL, along with their likely Elamo-Dravidian languages were gradually replaced by invading “Aryan” warriors from around the ancient Ariana (Airyanem …

Sometime between the late Bronze-Age and the early Iron-Age, Iran experienced a linguistic and population replacement. Approximately 2700 years ago, the Indo-Iranian Medes established the Median empire which stretched from north-west Pakistan westwards to Turkey, and thereby brought genetic, linguistic, as well as ideological changes to Iran. Although not much is known about this period …

DISCUSSION We are proud to announce the availability to the public of our latest genetic admixture inference program named SAPDA (Shared Ancestral Population Defining Alleles). Eurasians, whether Europeans or Asians, are genetically very similar to each other, with genetic similarities far outweighing any differences they have. Most Eurasians have descended from a few thousand individuals …

Alternate methods of analysis using ADMIXTURE & PCAs

7 Comments / Admixture Calculators / By

The use of PCAs and ADMIXTURE program is widespread in the study of population histories, although the most common way those programs are used, using all available SNPs, including common variants, pruned for maximizing the genotype rate among samples in the dataset, may not be best for accurately inferring shared drift amongst populations. Here I …

An Admixture Calculator for Eurasians

Genealogical testing companies use highly admixed references In other posts, I have mentioned the problems with ancestry proportion tests from genealogical testing companies such as 23andMe, AncestryDNA, and FTDNA, and how useless the test results can be for describing the population history and admixture for individuals from various parts of Eurasia. For example, what does …
