These are maps of modern distribution of haplogroup R1b-M269 and its main subclades, using natural neighbour interpolation.
The expansion of extant R1b-M269 subclades was most likely associated originally with the expansion of Proto-Indo-Europeans.
Data used is mainly from Myres et al. (2011). For DF27, newly reported data includes reports by Solé-Morata et al. (2017). Both have been reviewed, including more recent papers, in data reported by Hernández et al. (2018).
