1) Domestication of mammals Flashcards
1
Q
Domestication
A
Process where:
- A population of animals becomes accustomed to human provision + control
- Taming + breeding of domesticated animals
2
Q
Microevolution
A
Small-scale genetic changes over a few generations
3
Q
Give the levels of microevolution
A
- Mutation
- Natural selection
- Artificial selection
- Gene flow
- Genetic drift
- Non-random mating
4
Q
Gene flow
A
Transfer of genes from one population to another
5
Q
Genetic drift
A
Change in the frequency of alleles in a population
6
Q
Macroevolution
A
Large scale gene change over a geological time period
7
Q
List the degrees of domestication
A
- Wild
- Predomesticated
- Semi-domesticated
- Full domestication
- Dedomesticated
- Redomesticated
8
Q
Wild
A
No human interference
9
Q
Predomesticated
A
- Raised in captivity
- Bred by human control
- No behaviour difference from wild
10
Q
Semidomesticated
A
- Raised commercially (ranch/farm)
- In large numbers for food
- Group or appearance is not altered
11
Q
Full domestication
A
- Bred and raised by humans for many generations
- Altered group and appearance
12
Q
Dedomestication
A
- Domesticated animals become wild
- Feral animals
13
Q
Redomestication
A
Feral animals return to domestication
14
Q
List reasons for domestication
A
- Produce food/resources
- Labour
- Protection
- Leisure
15
Q
List the criteria to be considered domesticated
A
- Flexible diet - Wide variety of food
- Fast growth rate
- Ability to breed in captivity
- Pleasant disposition/temperament
- Modifiable social hierarchy (Humans top)
