Occurs from the interaction between the environment and the inherit variability in a population. Individuals best suited to their environment will pass down those favorable traits to their offspring.

• Evolution

• Artificial Selection

• Natural Selection

• Vestigial Structures

• Homologous Structure

Darwin proposed that new species evolve from ancestral forms by-

• the gradual accumulation of adaptations to changing environments.

• the inheritance of acquired adaptations to the environment.

• the accumulation of mutations.

• the exponential growth of populations.

Which statement about natural selection is most correct?

• Adaptations beneficial in one habitat should generally be beneficial in all other habitats as well.

• Different species that together occupy the same habitat will adapt to that habitat by undergoing the same genetic changes.

• Adaptations beneficial at one time should generally be beneficial during all other times as well.

• Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.
