Divergence times between giraffe clades in Figure 1 based on mtDNA control region sequence data. Maximum likelihood values of parameters θ, M (2Nm), and T (t/2N) estimated with a non-equilibrium coalescence model using the program MDIV [19]. Time divergence values (in million years, MY) are given for three mutation rate estimates for the giraffe mtDNA control region (0.05, 0.10 and 0.15 substitutions per site per MY), and a generation time of 4 years. per = G.c. peralta, rot = G.c. rothschildi, ret = G.c. reticulata, tip = G.c. tippelskirschi, ang = G.c. angolensis, gir = G.c. giraffa.
