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
The phenotype changed, which resulted in a black color adaptation.
The peppered moth had white bodies and wings, peppered with black. This coloration blended well into the original British countryside, hiding them from their predator the birds. Factories of the early industrial revolution covered everything with soot. Now the white stood out against the black surroundings making them easy targets for birds. Over time the white moths were wiped out. But, a few of them were darker in color, these survived and multiplied such that the white peppered moth was replaced buy the dark ones.
Black moths were selected for when the trees turned black.
the moths with the high fitness were selected for
The black moths were more fit for survival, so their phenotype frequency increased.
All owls have night vision. Since the desert can get so hot, most animals, including owls, come out at evening or night to avoid the heat of day. Since they're active at night, it's good to have nocturnal vision.
Some desert owls are elf owls, pygmy owls, burrowing owls, great horned owls.
It allows them to hunt when it is cooler.
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)
An adaptation must fit the environment -Apex
They make the species more genetically diverse
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.
