Evolution Of Behaviour Flashcards
1
Q
What can fossil records show?
A
- composition, forms and location
- interactions between species
- predator-prey interactions can be inferred
- mating behaviour
- how animals moved around environment
- modes of locomotion
- predation
- habitat selection
- vocalisation
2
Q
Define competitive method
A
Comparing species examine behaviour patterns to determine how they evolved
3
Q
Three ways to compare species
A
- differences and similarities
- assumes behavioural traits are heritable
- behavioural traits evolved from simple to complex forms
4
Q
Stages of balloon flies evolution
A
- Independent hunting
- Male gives nuptial gifts
- Male uses prey to attract female
- Same but prey wrapped in silk
- Prey wrapped in balloon form, mates with female while she eats
- Same but no fluid in prey
- Small, useless prey, no value
- No prey present
5
Q
Limitations of comparing species
A
- some animals stay unchanged
- not all perfectly adapted
- ancestral vs derived traits
