Evolution is the process of change in all forms of life over generations.

What is natural selection?

Natural selection is the mechanism by which certain traits are favored for survival in a given environment.

What is adaptation?

Adaptation is the process by which organisms adjust to their environment to increase their chances of survival and reproduction.

What are mutations?

Mutations are random changes in an organism's DNA that can lead to genetic variation.

What is speciation?

What are homologous structures?

Homologous structures are similar anatomical features in different species that suggest a common ancestry.

What is artificial selection?

Artificial selection is the intentional breeding of plants or animals for specific traits by humans.

What is the fossil record?

The fossil record is the collection of all known fossils that provides evidence of past life.

What is convergent evolution?

Convergent evolution is the independent evolution of similar traits in unrelated species.

What is the significance of the peppered moth?

The peppered moth is an example of natural selection and adaptation in response to environmental changes.

What is the role of mutation in evolution?

Mutations provide the genetic variation necessary for evolution to occur.

What is sexual selection?

Sexual selection is a form of natural selection that operates on traits related to mating.
