Ultrametric Time Tree. Mean divergence times estimated by BEAST with a fixed clock of \(2.285\times {10}^{-8}\) substitutions site⁻¹ year⁻¹ are shown. L5'7 clades are highlighted in blue. Black circles denote clades with \(\ge\) 0.9 posterior probability, open circles denote clades with \(\ge\) 0.5 but \(<\) 0.9 posterior probability, and polytomies include any clades \(<\) 0.5 posterior probability. Previous haplogroup assignments (in square brackets) are denoted as follows: * = L5, A = L5a, B = L5b, C = L5c (which is an undescribed haplogroup).
