Chapter 2 - Domestication (part 2)

Gradual process through which Changes occur to the animal. - change will only occur if the mighty gets survival experience and the **

• human decision based on rapid change

Docility toward humans - the original target of selection for coexistence of animals and humans

• with artificial selection, genetic modifications mar be chosen despite offering no survival advantage to the animal • greater variation can be seen within a domesticated animal population than that through natural selection

• rigorous selection for tameness created changes in behavior, physiology, and morphology • there were changes in the reproductive pattern (Lengthened mating season and breeding out of season)

Selecting for tameness triggered changed in mechanisms that control development

• breeding of animals in captivity • goal oriented • increased reproduction success • atrophy or reduction in organs • greater demonstration of adaptability • process facilitated by subjugation to humans

D - genetic modification, markers T - conditioned behavioral modification

• Large social group with a hierarchical structure • Promiscuous mating with external signs of mating • Adaptability to wide range of dietary and environmental conditions • Low reactivity towards humans • Precocial young

• forced relationship between humans and animals -human control of animal environment • started with control of animals within wild environment • further capture of young animals with subsequent slaughter at mature stages • ability to attract animals (communities near water) • maintain mature animals and use of future offspring [animal keeping]

• intentional human selection of animals for farming [animal breeding]

• transportation • economic status • social and religious ceremonies • research

Once domesticated animals that have returned to a wild state
