What adaptation helps penguins and seals stay warm?

• long necks

• a thick layer of fat

• long fur

What theory proposes that organisms with traits better suited to their environment are more likely to survive and reproduce?

• Acquired Characteristics

• Embryology

• Survival of the Smartest

• Natural Selection

The fur of the snowshoe rabbit changes to a lighter color in the winter. This allows the rabbit to blend in with its surroundings. This change is an example of:

• Adaptation

• Extinction

• Competition

• Succession

Due to genetic inheritance, members of a species can be slightly different from another in their traits. This is known as...

• Variation

• Overproduction

• Competition

• Evolution

Animals may fight, make threatening sounds,and act aggressively toward members of the same species. These behaviors usually occur as the result of:

• Adaptation

• Evolution

• Competition

• Variation

When every organism of a species has died.

• Evolution
• Natural Selection
• Extinction
• Artificial Selection

Bird's beaks evolve mainly due to the type of ___________________ available.

• food
• water
• shrubs
• mates

Organisms with differences/variations that are helpful will ______________________

• live longer
• become extinct
• show no change

What can happen to a species over time if some of the organisms have an advantage?

• The population will decrease
• The population will become extinct
• The population will slowly increase
