Natural Selection

Drawn observed several different types of finches.  Why are there so many different types?

• Finches live in different places, but eat the same food.
• Finches live in the same place, but eat different types of food.
• Finches live in different habitats and eat different types of food.
• Finches are found all over the world.

Skunks' musk glands hold a putrid smelling liquid.  What kind of adaptation is this?

• Physical adaptation
• Behavioral adaptation
• Environmental factor
• Adaptation

Sea turtles cannot retract their head or limbs.  (They cannot pull their head and limbs into their shell.)  What adaptation helps the sea turtle survive from predators in the ocean?

• Hard outer shell to pull in its head and limbs
• Mimicry and coloration
• Ability to swim and dive
• Leaving the ocean to lay eggs

Why do all of these organisms have long legs?

• Behavioral adaptation
• Physical adaptation
• None of the organisms have a recessive gene.
• The berries are high off the ground, so the species adapted to teach the food.

An adaptation is

• how animals change over time.
• a characteristic that helps and organism survive in its environment.
• a theory of how organisms change.

Environmental factors affect an organism's survival.  For example, two short term changes are

• fire and climate fluctuation.
• fire and drought.
• drought and climate fluctuation.
• climate fluctuation and pollution.
