Abstract

The status on the origins of haplogroup R1b remains split between the Iberian Peninsula prior to the Last Glacial Maximum (LGM) and a West Asian origin coinciding with the Neolithic expansion. The majority of focus on subgroup R1b-V88 has concentrated on African populations and neglected European and West Asian populations. To get a complete understanding of the back to Africa migration, a holistic network approach is necessary. Biogeographical Multilateration (BGM) illustrates directional flow as well as chronological and physical origins at the haplogroup level. The resulting phylogenetic relationships for R1b-V88 support an Iberian origin, a Mediterranean expansion and a Europe to Africa back migration.
