Haplogroup I-M438
Haplogroup I-M438, also known as I2 (ISOGG 2019), is a human DNA Y-chromosome haplogroup, a subclade of haplogroup I-M170. Haplogroup I-M438 originated some time around 26,000–31,000 BCE. It originated in Europe and developed into several main subgroups: I2-M438*, I2a-L460, I2b-L415 and I2c-L596. The haplogroup can be found all over Europe and reaches its maximum frequency in the Dinaric Alps (Balkans) via founder effect, related to the migrations of the Early Slavs to the Balkan peninsula.
