I-P37.2 (Y-DNA)

This project is for people who have tested and been assigned the paternal haplogroup I2a1 (P37.2) and also for people who are believed to have belonged to this paternal haplogroup based on tests done on descendants.

Formerly: I2a

Origin

Haplogroup I2 might have originated in southeastern Europe about 15,000 to 17,000 years ago. The P37.2 subgroup seems to have originated about 10,700 years ago (plus or minus 4,800 years). However, the known members of this group seem to share an ancestor who lived more recently, only about 8,000 years ago (plus or minus 4,000 years).

I2a1-P37.2 - Two examples of I2a1 have been found in the DNA of Neolithic farmers. They were among the burials in the Cave of Treilles in Aveyron, in the South of France. The Treilles culture of c. 3000 BC is the very last phase of the Neolithic in the region before the arrival of copper-workers and the Bell Beaker culture. 4 Ken Nordtvedt considers their haplotypes consistent with I2a1a -M26.
