From: Out of southern East Asia: the natural history of domestic dogs across the world
Demographic and migration histories for the domestic dog. (A) Tree topology inferred from TreeMix when no migratory tracts are allowed. The drift parameter is the amount of genetic drift along each population. Further inferred migratory tracts are shown in the bottom-left corner of the panel. The three important nodes are those that we have provided extensive dating information. (B) The PSMC plot for all the individuals. Gray lines plot the benthic δO18 levels, which are a proxy for global temperature61. The span of the current ice age (Quaternary ice age, 2.58M-now) is shown with an arrow. The x-axis is time plotted in log scale and the y-axis is effective population size. (C) Inferred population demographic history between wolves and southern East Asian indigenous dogs using the joint site frequency spectra. (D) A proposed migratory history for domestic dogs across the world based on the evidence from our study. Solid arrows represent migratory tracts that we have dating information, while dashed arrows indicate those without accurate dating.
