| Question | Answer |
| Domestication Steps - Zeuner 1963 | Initial association with free breeding. Confinement. Confinement with breeding in captivity. Selective breeding and/or breed improvement. |
| Mutualism | Mutualists relationships leading to COEVOLUTIONARY PROCESSES between human & domesticates |
| Livestock & Plant Domestication | Initial management of morphology of wild plant/animal. Approx. 11,5000 ybp. Cyprus evidence with cattle, goats & pigs - more accurate dating with new tech. |
| Successful Domestication - Diamond, 1999 | We've domesticated 15/148 non carnivorous mammals over 45kg. And 10/10,000 bird species. |
| Pre-adaptation to Domestication - Obstacles. Diamond, 2002 | Diet not easily supplied. Growth rate was slow. Long birth spacing. Nasty disposition. Reluctance to breed in captivity E.g. wild elephant/panda - due to lack of dominance hierarchies. Tend to panic. |
| Start of Animal Domestication | Neolithic period. 12,000-14,000 ybp. Improvement of human hunting skills. New tech - food storage etc. Competition between social groups/societies. N. Guinea had agriculture already - others followed. But dispersed domesticated animals were affecting the natural food chain. Hunter-Gatherers suffered due to food loss. |
| Climatic factors | Early modern domestication only occured in areas already on the map. US& China witnessed an eco disastor - Iran/Iraq/Syria dried out totally and suffered soil erosiion. |
| Consequences of Neolithic Revolution | Sedentarialism - Transition from nomadic lifestyle to 1 permanent location. Food supplies - political gathering/armies over food sources/stores. Epidemics - zoonotic diseases + high human densities. Human population genetics - led to genetic changes e.g. lactose tolerance. Diet - alcohol tolerance, saturated fat, salt. Eco. Disasters - high human density meant more heavily affected. |
| Ecological Disasters | More heavily affected due to high human density, crop reliance, trading of animals etc., distribution of cattle |
| Domestic Goat | Domesticated Capra hircus. Similar in size than ancestor - genetic drift. Hunter-gatherers would have killed larger ones, so intermediate size domesticated. More males died because they are bigger. |
| Domestic Chicken | Gallus gallus. 4 orig. wild spp. of chicken. Actually from jungle fowl. Multiple material on history of dom. chicken. But all from ancestral app. |
