Document Summary
Dogs were the first animal to be domesticated around 40,000 years before present. The pathway of dog domestication was likely one of commensalism to mutualism then domestication. The domestication step involved natural selection, while the selective breeding involves artificial selection. Domestication is a process whereby humans bring an animal into captivity and take control of its reproduction, for the purpose of producing desirable traits through directed, selective breeding. Mutual dependence and benefit (from evolutionary, not necessarily ethical, perspective) There are many mutualisms in nature, but rare between human and wild animal species (where no domestication is involved, only natural selection) Through rare, this is one clear example of humans and a wild animal species mutualism: human and honeyguide. Commensalism ----- mutualism ------ domestication begin around 40,000 bp. Earliest unambiguous evidence of domestication from burial in near. Chauvet cave wolf and child tracks 26,000 bp. Only few animal species have proved capable of being domesticated.
