What are proximate and ultimate questions?
Proximate - How questions:
- causation (mechanism)
- development (ontogeny)
Ultimare - Why questions:
- evolution (phylogeny)
- function (selection)
What does level of analysis mean?
Refers to whether you’re studying ultimate or proximate causes
Give an example of testing a proximate hypothesis
Orientation in bee wolves
Female bee wolf provisions her underground nest with honeybees
She leaves on hunting trips but always finds her way back to the nest
On flying away she circles to presumeably memorise landmarks near the entrance
After hunting trip she will return to the wrong location if the landmarks have been moved by an experimenter
Give an example of testing an ultimate hypothesis
Eggshells are removed by parent birds
The closer shells are to gull nests the greater the predation
This supports the hypothesis that removing shells after hatching increases fitness
What are the four steps in the scientific method
1) ask a question about an observed behaviour
2) establish a hypothesis to potentially explain what has been seen
3) set up predictions based on the hypothesis
4) test these predictions by gathering appropriate data (field observations, experiments etc)
