BIOL 2020 Lecture Notes - Lecture 2: List Of Domesticated Animals, Commensalism, Selective Breeding
Document Summary
Domestication the process of controlled breeding in order to tame a population to live in close association with humans and have a mutually beneficial relationship. Symbiosis close and often long-term interaction between different biological species. Mutualism biological relationship where both parties" benefit. Commensalism biological relationship where one benefits, and the other is neutral. Parasitism biological relationship where one benefits and other is harmed. (cid:862)hu(cid:373)a(cid:374)s ha(cid:448)e succeeded in truly domesticating only 14 animal species out of a(cid:271)out 148 (cid:272)a(cid:374)didates(cid:863) 13 out of 72 large animal candidates in europe & asia have been domesticated. All domesticated animal species in africa have been imported there. Breeding animals in captivity artificial selection. With continued selective breeding, the appearance and behaviour of the species changes over time. Mutually beneficial to us and the domesticated animal: require food from humans. Bred under human control selective breeding/artificial selection: on a population of animals, over a long period of time.
