The dog population in Bali, currently estimated at 800,000 individuals, is thought to have become established and relatively isolated from other dogs thousands of years ago. In collaboration with Niels Pedersen, Sarah Brown, and others, this research seeks to determine how long and to what extent this population has undergone independent evolution. We use DNA from mitochondrial, y-chromosome, microsatellite, and MHC loci to compare genetic diversity and accumulated mutations to worldwide populations of dogs and wolves.
