Evolution

______ _________ explains how two or more organisms could evolve similar traits even though they are not related to each other.

• Convergent evolution

• Reproductive isolation

• Derived characters

• Divergent evolution

__________ structures are similar characteristics that have evolved separately in two unrelated organisms.

• Analogous

• Homologous

• Vestigial

• Phylogenic

______________ is the process by which populations change in response to their environment.

• Natural selection

• Adaptation

• Reproductive isolation

• Divergence

________ structures are reduced in size or function.

• Vestigial

• Homologous

• Analogous

• Phylogenetic

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population
