DNA (haplotypes) originating from the Denisovans can be found in the genomes of Indigenous Australians and Melanesian Islanders. However, the same DNA markers are not found in the genomes of people native to Africa. Why are Denisovan haplotypes found in Indigenous Australians and Melanesian Islanders but not in people native to Africa? Homo sapiens populations moved out of Africa into Asia and then interbred with the Denisovans before migrating to Australia and Melanesia. Homo sapiens populations interbred with the Denisovans before leaving Africa. The Denisovan haplotypes appeared in both Homo sapiens populations independently due to spontaneous mutations. Homo sapiens populations interbred with the Denisovans and then migrated into Africa, Australia, and Melanesia.
