Genetic research suggested African origins for the donkey, the Science Daily quoted lead researcher Fionna Marshall as saying. Knowing the exact time and location for domestication was difficult because signs of early domestication could be hard to see. The findings show that traces of human management could indicate domestication before skeletal or even genetic changes. Domestication of the donkey from the African wild ass was a pivotal point in human history. It transformed ancient transport systems in Africa and Asia and the organisation of early cities and pastoral societies.
