Evolution and Natural Selection Quiz

What is natural selection?

• The process by which individuals that are better suited to their environment survive and reproduce most successfully.

• The ability of an animal to learn from its environment and change its behavior accordingly.

• A random process that leads to the development of new species over time.

• The process by which individuals intentionally adapt to their environment.

Which level of classification is broader, genus or species?

• Genus.

• Species.

• They are the same.

• It depends on the organism.

What is an example of a behavioral adaptation?

• The thick fur of an arctic fox.

• Birds migrating south for the winter.

• A plant's leaves turning towards the sun.

• The camouflage of a chameleon.

Why is genetic variation important for natural selection?

• It ensures that all individuals in a population are identical.

• It provides a mechanism for populations to evolve over time.

• It decreases the survival chances of a population.

• It has no impact on natural selection.
