4.4 - Primate Behaviour Flashcards
1
Q
Captive studies
A
- research instituties
- observed 24/7
- control food, responses recorded
- unnatural setting
- individual behaviour best for this
2
Q
semi free ranging
A
- can establish territories, easily observable, still not in conditions evolved
3
Q
field studies
A
- Natural habitat, they evolved
- Specific environmental conditions select for specific traits
- Home ranges… hard to stay in contact
- Years of research needed
- need to get used to humans
- Most informative
4
Q

5
Q
Reproductive asymmetry
A
- difference between male and female reproductive potential

- Primates tend to give birth to single offspring at a time
6

- tail raising
- presenting
12
Q
