indicates that domestication of dogs may have occurred repeatedly in different geographic locations rather than with a single domestication event Back in the early 90s Laurie Corbet said that the conditions that led to the domestication of the dog were common and widespread and so if it could have happened in East Asia it could have happened in Central Eurasia Southwest Asia and Siberia as well Looking at them I thought for a long time that they seem to have separate ancestors but since have gathered that current evidence shows all existant dogs decend from one single domestication event somewhere in east Asia This evidence however indicates that there once were dogs that evolved at another place and time but seem to have left no ancestors
