Phylogenetic Relationships within and among Gorillas, Chimps, & Humans
This is a Neighbor Joining (NJ) tree of distances
over 15,447bp of the mitochondrial DNA coding region, for
two pairs of Gorillas & Chimps, one Neandertal, and
three Anatomically Modern Humans (AMH) assigned
to haplogroups L1, A, and U
[African, First Nations, and European]. Note the similarity
to a Coalescent tree with recent origination of variation:
branches (edges) within groups are much shorter than those
among groups. The tree confirms a closer relationship
between human and chimps, rather than humans and gorillas.
