The diagram shows an image of a Pterosaur wing, bat wing, and bird wing. These are all different organisms, but share similar wing structures. If these structures are similar due to common ancestry, which of the following best describes them?

•  Vestigial Organ

•  Embryological Similarities

•  Homologous Structures

•  Analogous Structures

Which of the following pieces of evolution evidence deals with comparing similar structures in various species?

• fossil record

• comparing embryology

• comparing biochemistry

• comparing anatomy

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
