The diversity can be explained by other factors though.
The Balkans have been subject to 5000 years of migrations from the Eurasian Steppes, each bringing new varieties of R1a.
A third possibility is that R1a tribes split in two around Kazakhstan during the Late Paleolithic, with one group moving to eastern Europe, while the other moved south to Iran.
Some people have theorized that R1a was one of the lineages of the Neolithic farmers, and would have entered Europe through Anatolia, then spread across the Balkans toward Central Europe, then only to Eastern Europe. The first is that 99% of modern R1a descends from R1a1a (M417), a subclade that clearly expanded from the Bronze Age onwards, not from the early Neolithic.
The most likely place of origin of R1a is Central Asia or southern Russia/Siberia.
R1a is thought to have been the dominant haplogroup among the northern and eastern Proto-Indo-European language speakers, that evolved into the Indo-Iranian, Thracian, Baltic and Slavic branches.
The Proto-Indo-Europeans originated in the Yamna culture (3300-2500 BCE).
