  1. * Haplogroups not described in van Oven 2009: F1a1d, M7b4, and N9a10 (see text).
  2. # Molecular dating of mtDNA sequences for coding region synonymous mutations was obtained using a rate of one synonymous mutations per 7,884 years [53] or per 6,764 years [51].
  3. $ Molecular dating of mtDNA HVS-1 sequences (n > = 5) was obtained using a rate of one transition per 19,171 years when Rho method was applied according to [53], or per 20,180 years according to [52, 64].
  4. NA: Not applicable.
  5. Note: Inferences made from such dates warrant caution as they have considerable uncertainty and may be inaccurate [33].
  6. &All lineages were identical.
