Domestic dogs are good friends of human beings. although they are very different from each other, these different groups of domestic dogs share a common ancestor-gray wolves. Gray wolves are very widespread in the global divisions, but domestic dogs everywhere do not evolve from gray wolves everywhereFrom genomic DNA comparing the genetic diversity of domestic dog populations from different regions, the researchers found that domestic dog populations from southern East Asia had the highest diversity. At the same time, the structure of the phylogenetic tree also supports the common birthplace of domestic dogs. In the phylogenetic tree, the end of each branch represents a population, and the closely related population will be closer on the tree. In this study, domestic dog samples from southern East Asia were located at the base of the phylogenetic tree.
