☆☆☆☆☆a species can gradually change into new species
Evolution.
Descent with modification
The ability to survive and reproduce
There was very little need for skilled labor
There must be genetic variation in the population
The system must not be in hardy-weinberg equilibrium.
resources must be limited in the ecosystem
Leaves that hold water
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.
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.
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)
A beak that can dig into thick trees.- apex :D
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
Random processes are not part of the theory of evolution by natural selection.
You mama
The allele frequency does not change.
The dark colored moths were more fit.
