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

• random mutations

• variation in a species

• selective breeding

Why might it be useful for a species to have a lot of variations (differences)?

• They cannot be seen by predators.

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

• It is helpful in asexual reproduction.

• They don't recognize each other.

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 cannot reproduce.

• They are not the same species.
