• Analogous Structures

• Homologous Structures

• Vestigial Structures

A study of the body structures of animals to know how they evolved from the likes of their common ancestors for the purpose of adapting to their environment.

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
