Evolution Quiz

Which of the following best describes the process of natural selection?

• Organisms choose their traits to adapt to the environment.

• Traits that enhance survival and reproduction become more common in a population over time.

• All individuals in a population evolve to possess the same traits.

• Natural selection occurs when humans selectively breed plants or animals.

How does adaptation benefit a species in a changing environment?

• It allows all individuals to survive regardless of the change.

• It ensures that the species will not face any threats or challenges.

• It increases a species' ability to survive and reproduce under new environmental conditions.

• It prevents any mutations from occurring in the species' DNA.

Which scenario best illustrates speciation?

• A type of bird develops different songs.

• A population of lizards is separated by a natural barrier, leading to the development of distinct traits in each group.

• A cat learns a new trick from its owner.

What role does genetic variation play in natural selection?

• It has no effect on natural selection.

• It decreases the survival rate of a species.

• It provides the raw material for selection to act upon.

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

Why is it incorrect to say that individuals evolve?

• Individuals adapt, but only populations evolve.

• Individuals evolve, and so do populations.

• Evolution is a static process that does not involve individuals.

• Individuals can choose to evolve whenever necessary.

• Genetic isolation and subsequent evolutionary changes.

• A single mutation that is beneficial.

• Agreement among individuals to become a new species.

How does an environmental change influence natural selection?

• It has no impact on natural selection processes.

• It may create new selective pressures that favor different traits.

• It ensures that all organisms will adapt successfully.

• It decreases genetic variation within a population.

• The consistent temperature of the environment.

• The genetic variation among individuals in the species.

• The uniformity of the species across different environments.
