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 …

ABSTRACT DNA from hundreds of ancient humans remains spanning the last 7000 years has been sequenced over the past few years in the “Southern Arc” region of West Asia and surrounds. Using DNA we here investigate the demographic changes that occurred over the past 2000 years in the Anatolia region as they pertain to the …

Indo-Europeanization of Iran & Kurdistan – The genetic substructure of the Indo-Iranian invaders

Admixture Calculators, Analysis, Central Asian Genetics, East Asian Gene Flow, Genotyping, Iran Genetics, Iraq Genetics, Iron Age Genetics, Kurd DNA, Kurd Genetics, Medes Kurds, Uncategorized / By

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 …

SAPDA – A new publicly available admixture inference program

Admixture Calculators, Analysis, Commercial DNA Testing, East Asian Gene Flow, New Ancestry Calculator / By

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 …

Impact of the Iron Age Saka and Scythians on the demography of Kurds

31 Comments / Analysis, East Asian Gene Flow, Genotyping, Kurd Genetics, Uncategorized / By

ABSTRACT The flood of recently sequenced ancient DNA has tremendously increased our understanding of demography of various Eurasian modern populations. Thanks to the recently sequenced genomes in Damgaard et al, Narasimhan et al, Olaide et al, Lazaridis et al, and Mathieson et al, and the suite of tools within Admixtools, detailed in Patterson et al  …

The Onge versus other Indian & SE Asian ASI proxies

Analysis, Ancestral South Indian, East Asian Gene Flow / By

DISCUSSION The Onge are an endangered relic population with only about 100 surviving members, who inhabit the Andaman Islands in the Indian Ocean. They are classified as Negritos, and are related to  Negritos from neighboring NE India, Burma, Cambodia, and Indonesia. The unifying physical characteristics of Negritos are short stature, curly hair, and dark pigmentation. …

A detailed look at East & North Eurasian Gene Flow to South & West Asians

10 Comments / East Asian Gene Flow / By

Here I perform a detailed analysis of East and North Eurasian gene flow to South, South-Central, and West Asians by doing a one-to-one comparison of genomes sampled at about 404,000 Single Nucleotide Polymorphism (SNP) positions, using the program BEAGLE. To do this I utilize many genomes from northern and eastern Asia publicly available from the …
