Natural Selection

A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

Why might it be helpful for a species to have a lot of variations?

• They can't be seen by predators

• If the environment changes, they might be better able to adapt

• It is helpful in asexual reproduction

• They don't recognize each other

On the Galapagos Islands, different finches evolved on different islands to fit their environment. When a species develops unique traits because it is trapped in one area this is called:

• Geographic isolation

• Geologic separation

• General relocation

• Genetic differentiation

The male and female black widow spider look very different. However, we know they are the same species because:

• They reproduce creating fertile offspring

• They reproduce creating infertile offspring

• They cannot reproduce

• They are not the same species
