One English moth species has both light and dark colored individuals. The light colored moths are more numerous because they blend in with the light colored lichens common to English trees. These moths will likely survive to pass on genes to future generations. This is an example of

• Mutation

• Evolution

• Dominant genes

• Fossilization

What do transitional fossils best support?

• The theory of biological evolution

• The law of superposition

• The theory of geological evolution

• The theory of continental drift

Butterflies and birds use their wings to fly, but the structure of their wings is different because the wings did not evolve from a common ancestor. These are an example of __________ structures.

• Vestigial

• Homologous

• Analogous

• Embryological
