Figure 3: Inferred demographic history for the wild wolves and the Chinese indigenous dogs.
From: The genomics of selection in dogs and the parallel evolution between dogs and humans

The extent and ancestral population sizes of two species are labelled. The migration rates between two populations are also labelled. As the current wolf’s average diversity θ is equal to 0.00141 (θ=4 Neμ) per kb and current wolves have an effective size that is 94% of the ancestral population, we estimated that the effective population size of the ancestral wolf to be around 53,000.
