2. Figure 1
Phylogenetic tree of human mitochondrial DNA haplogroups commonly observed in Europeans, southwest Asians and North Africans.
The timescale is based on maximum likelihood (ML) estimates and a time-dependent complete mtDNA genome clock [9]. Haplogroups are colour-coded according to their region of origin (with minor gene flow ignored), although caution is needed given the large sample sizes needed for reliable phylogeographic inferences. Haplogroup nomenclature and an updated dataset can be found at [136].

3. Figure 2
Phylogenetic tree of human Y-chromosome haplogroups observed in Europe.
Some haplogroups are shared with Asians, Africans, or both. Nomenclature according to [42] and [137]. Although time estimates depend strongly on the method used and the assumptions made, an indicative timescale is provided, based on previous estimates [41,43,69,96,97,138–141]. The time location of the striped nodes as well as of the nodes at the end of dashed lines is arbitrary due to lack of information.
