• adaptations
• homologous
• fossils

Intermediate fossil forms are important evidence of evolution because they show

• how organisms change over time
• how animals behaved in their environments
• how the embryos of organisms develop
• molecular homologies

Darwin's observation that finches of different species on the Galapagos have many similar physical traits supports the hypothesis that these finches

• have the ability to interbreed
• acquired traits through use and disuse
• all eat the same type of food
• descended from a common ancestor

Whales are aquatic mammals that contain a pelvis bone.  Even though it does not aid in its movement, the function must have been used by a common ancestor of the whale.  Thus, the pelvis is referred to as a(n)
