• The individual's ability to adapt to changes in the environment

• The individual's characteristics that are most fit for their environment

Which of the following best describes the purpose of the diagram in the context of Darwin's conclusion?

• To show the diversity of modern horse breeds

• To show the change in horse size over time

What is natural selection?

• A process where individuals with beneficial traits reproduce more often and pass on those traits to their offspring.

• A process where all individuals in a population are equally likely to survive and reproduce.

• A method by which individuals adapt to their environment through conscious choices.

What does the term 'population' refer to in the context of natural selection?

• All members of a species that live in an area.

• A collection of various species in a given environment.

• The total number of individuals in a community.

What occurs as a population's genes and frequencies change over time?

• Mutation

• Evolution

• Metamorphosis

What is a gene pool?

• A collection of DNA samples

• All the alleles in a population

• A storage area for genetic information

What would happen to the gene pool if any individual that had a red allele didn't survive?

• The allele would not be part of the population

• The allele would not be passed down

• The population would change

What can cause genetic changes?

• Diet and exercise

• Mutations

• Technology and innovation

What is an adaptation in the context of biological organisms?

• A learned skill that an organism acquires during its lifetime.

• An inherited characteristic that increases an organism's chance for survival.

• A temporary change in an organism's behavior due to environmental changes.

How do adaptations affect a species over time?

• They make the species less common in its habitat.

• They have no significant impact on the species.

• They make the species more adapted and common in its habitat.
