What is the proximate and ultimate cause of migration?
Give this one a try later!
Proximate → long-distance movement related to change in seasons
Ultimate → cope with habitat shift to maximize fitness
, Proximate → how actions occur (what mechanism allows this?)
Ultimate → why actions occur (why did this evolve this way?)
- Rocks weather and release ions
- Nutrients imported through streams or wind
- Primary producers fix carbon
- Nitrogen-fixing bacteria

How does the Galapagos finches exhibit non-Lamarckian evolution?
Give this one a try later!
Males with heritable traits that enhance their chance of mating are selected for.
Selection acts stronger on males, since females' pickiness of mates makes them
desirable to males.
