What does natural selection cause

Evolution.

What is an adaptation

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

What is the fitness of an organism

The ability to survive and reproduce

How does high biodiversity affect an ecosystem

It makes the ecosystem able to survive disturbances.

When will natural selection occur

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.

How do adaptations affect a species

They make the species more genetically diverse

What is a reproductive strategy

The method an organism uses to produce offspring

the way that a species creates offspring

What principles is not part of Darwin's original theory of evolution by natural selection

Random processes are not part of the theory of evolution by natural selection.

Creation of an unnaturally uniform sample to represent a diverse population can be avoided by

selecting individuals at random. Apex 8)

What must be true for Hardy-Weinberg equilibrium to occur

No disruptive circumstances must be present in random mating in a population for Hardy-Weinberg equilibrium to occur.

Mating must happen randomly.

No allele can give an advantage
