introduction Evolution

The white feathers of a snowy owl allow it to blend in with its environment during the winter months (snow). This is an example of ________________

• Species
• Environmental Change
• Adaptation
• Variation

The slight differences amongst a species, like different shaped bird beaks, are called

• genes.
• variations.
• traits.
• theories.

Sometimes referred to as "survival of the fittest," this process allows those traits which are most favorable to be passed on to the next generation and those which are not to be eliminated.
