Animal Domes Flashcards
Species types
Domestication
Animals around the house. Reproductive control by humans. Participation or people and animals with genetic change.
Exception cats: reproduce on their own
Domestication characteristics
Diet (herbivore, omnivore) Growth rate (faster is better) Easy reproduction (
Characteristics of Domestication
- Diet (herbivore/omnivore)
- Growth rate (faster better)
- Reproduction (polygamy)
- Disposition
- Low panic tendency
- Social structure (herds, dominance pattern, no territories)
Exceptions of Domestication
Cats (diet), Geese (elaborate reproduction)
Changes in Domestication
- Coat/plumage color (behavior)
- retention of neotenic characters (remain cute)
- decrease in cranial capacity
- Increase genetic variability (i.e. novelty)
Transport Animals
Donkey/horse/bactrain camel/dromedary/llama, alpaca, yak
Wild Adaptation
Maintained and advantageous for Transport Animals
Why Domestication
70% of world depends on animals
30-40% agriculture is animal production
First Domesticated Animals
Dogs/Pigs
Taxonomy of Domesticated Animals
3-5 founder females
horses exception
Breed
group of domesticated animals, pheontypically similar enough to be grouped together. Interbreeding reproduces the parental type
Standardized Breed
breed that has an organization behind animal. Genetic isolation by design
Gentrification
removing population from original region and selecting it for uniformity outside original purpose (i.e. afghan hounds)
Industrial stock
subset of breeds selected for outstanding performance in narrow range of environment
Landrace
Genetic breed genetically isolated y default by cultural, geographic, communication factor. No organization (ADAPTATION IS KEY)
Feral
Domesticated animal returning to free-living state, subjected to natural selection.
Domesticated animals never return to status of wild animal and will always retain the smaller brain
General Pattern/Development
Domestication, then landrace or primitive breed, then standardized breed (maybe gentrification), then industrial stock.
Each step narrows genetic variability and increases predictability
Adapted Breed vs. Selected Breed
Adapted breeds is twice that of modern selected breed. i.e. small live animal > large dead animal
Breed Color
coloring will affect what is going on genetically, changing behavior (i.e. liver color in certain dog breeds)
Dog Domestication
camp following wolves, 100,000 BC in South east Asia
6 female ancestors
Key to domestication is dogs “read” people’s communication
Basal dog breed
village dog, lost genetic variation
Sight hound
Big eyes, don’t like pain,used for hunting for speed and sight
i.e. greyhound, whippet
Scent Hound
Smooth coats, bay while chasing, lop ears, hunting for smell
Pointer
bird hunting, liver color, European
Retrievers
lop ears, straight tails, retrieving is obedience
Spaniels
pointing, retrieving, docked tails
