Natural Selection

a species can gradually change into new species

Evolution.

a camel has humps to store water

a rabbit that has fur that blends in with snow

a trait that makes an organism more likely to reproduce

Food supply

The ability to survive and reproduce

There must be genetic variation in the population

The system must not be in hardy-weinberg equilibrium.

resources must be limited in the ecosystem

A) natural selection ( apex (

Mathus felt that population is limited by food supply so we need to limit population growth or starve.

The phenotype changed, which resulted in a black color adaptation.

Natural selection occurs when four conditions are met:

1. There is variation among individuals.

2. That variation is at least partially heritable.

3. That variation is linked to differential reproductive success.

4. More individuals are born than can survive and reproduce.

Why do organisms in different places have different traits (apex)

allele frequency change Apex :)

The method an organism uses to produce offspring

the way that a species creates offspring

Finches developed many different adaptations. For example, one type of finch had a short strong beak meant for cracking seeds, while another had a long narrow beak for gathering food from the inside of flowers, and cacti, therefore making each species more adapted to its specific environment and more able to gather food then they would on another island with a different main food source.
