Which best describes these fossils?

• homologous structures
• adaptive radiation
• fossil

A fossil of an extinct dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?

• This is purely by chance and isn't significant
• The extinct dinosaur and modern bird share a common ancestor
• All dinosaurs evolved into birds and that's why there aren't any dinosaurs alive today
• Dinosaurs choose to fly, and evolved into birds to escape predation and capture food

• comparative biogeography
• comparative embryology

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)

• analogous structure
• homologous structure

If species A and B have very similar genes and proteins, what is probably TRUE?

• species A and B share a relatively recent common ancestor
• species A evolved independently of species B for a long period
• species A is younger than species B
• species A is older than species B
