Researchers sequenced the genome from the
petrous bone of a c. 40 year old woman from Ganj Dareh,
GD13a. mtDNA analysis shows that she belonged to
Haplogroup X. She is phenotypically similar to the Anatolian early farmers and Caucasus Hunter-Gatherers. Her DNA revealed that she had black hair, brown eyes and was lactose intolerant. The derived SLC45A2 variant associated with light skin was not observed in GD13a, but the derived SLC24A5 variant which is also associated with the same trait was observed. Also genetically close to GD13a were ancient samples from Steppe populations (Yamanya & Afanasievo) that were part of one or more Bronze age migrations into Europe, as well as early Bronze age cultures in that continent (Corded Ware) in line with previous relationships observed for the Caucasus Hunter-Gatherers. Most Neolithic Iranian specimens from Ganj Dareh were found to belong to the paternal
haplogroup R2a. The to date oldest sample of
haplogroup R2a was observed in the remains of a Neolithic human from Ganj Dareh in western Iran (c. 10,162 years old). A late Neolithic sample (I1671) was found to belong to
Haplogroup G2a. According to one model, the Mesolithic/Neolithic Iranian lineage are inferred to derive significant amounts of their ancestry from
Basal Eurasian (), with the remainder ancestry being closer to
Ancient North Eurasians or
Eastern European Hunter-Gatherer (ANE/EHG; ). An alternative model without the need of significant amounts of ANE ancestry has been presented by Vallini et al. (2024), suggesting that the initial Iranian hunter-gatherer-like population formed primarily from a deep Ancient West Eurasian lineage ('WEC2', ), and from varying degrees of
Ancient East Eurasian () and
Basal Eurasian () components. The Ancient West Eurasian component associated with Iranian hunter-gatherers (WEC2) is inferred to have diverged from the West Eurasian Core lineage (represented by
Kostenki-14; WEC), with the WEC2 component staying in the region of the
Iranian Plateau, while the proper WEC component expanded into Europe. ==Gallery==
