R1a-rich ancient Siberians may have been as blond as today's Northern Europeans


More than 60% of the Kurgan (including Scytho-Siberian) samples successfully tested for pigmentation markers in a new study by Bouakaze et al. are inferred to have been blue- or green-eyed and fair-haired:

In the present study, a multiplexed genotyping assay for ten single nucleotide polymorphisms (SNPs) located within six pigmentation candidate genes was developed on modern biological samples and applied to DNA retrieved from 25 archaeological human remains from southern central Siberia dating from the Bronze and Iron Ages. SNP genotyping was successful for the majority of ancient samples and revealed that most probably had typical European pigment features, i.e., blue or green eye color, light hair color and skin type, and were likely of European individual ancestry.

The Y-DNA haplogroups reported for the ancient individuals include seven R1a1a and a single C (xC3). On the other hand, the mtDNA results show a lot more variety, with the following haplogroups present: U2e, U4 (2 instances), U5a1, H or U (3 instances), K2b, H5a, HV, T1 (2 instances), T3 (2 instances), T4, I, C (2 instances) F1b, G2a, N9a and Z.

The majority of the males who belonged to Y-DNA haplogroup R1a1 were very similar in terms of the few analyzed nuclear markers to the European reference population (Utah Americans from the HapMap project). On the other hand, the individual with haplogroup C clustered close to East Asians (HapMap Han Chinese and Japanese), along with another sample for which a Y-haplogroup assignment wasn't available.

Modern day Iranians seem to be Indo-Europesized. They Dont have any Indo-European influence at all. Their European scores are pretty low, yet they claim to have Indo-Iranian ancestors. And based on the Scythians DNA we can say that modern day Iranic people have nothing to do with Scythians,Samartians,Parthians etc....

I can only concur... the Indo-European theory seems to be debunked by these genetic researches. Scthians, Sarmatians and Parthians were most likely Turks.

The Sarmatian/Scythian/Saka peoples (even those in Central Asia/Siberia) show in general much less Mongoloid ancestry than the Central Asian Turkic peoples according to both genetic and physical analyses. The modern-day peoples of Iran have little ancestry from the original Iranic invaders of what is now Iran, as what is now Iran was well populated already during the Iranic migration to what is now Iran. This explains the genetic/physical differences between the Sarmatian/Scythian/Saka peoples and the Iranic-speaking peoples of what is now Iran despite the fact that both groups are Iranic-speaking. Parthians inhabited a territory adjacent to modern-day Iran, so they probably were not genetically and physically much different from the modern-day peoples of Iran.
