• homologous
• heterologous
• analogous
• vestigial

• Homologous
• Vesitigial
• Analogous

The hind leg bones in a whale are examples of

• homologous structures
• analogous structures
• fossils
• vestigal structures

Human wisdom teeth

• Homologous
• Analogous
• Vestigial

An example of a homologous structure 

• human arm and bird wing
• rat appendix  and human appendix
• wing of butterfly and bird wing

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

A body part that is not used or not working by a modern organism but which was needed by its ancestors is called a

• Homologous structure

• Analogous Structure

• Vestigial Structure

• Pharyngeal Pouch

The study of evolution by studying the development of the fertilized egg cell and its development into an organism is called

• Molecular Biology

• Evolution

• Embryology

• Paleontology

All vertebrates have this structure which indicates that they are evolved from a distant same ancestor

• A chambered heart

• Lungs for breathing air

• kidneys to clean the blood

• Pharyngeal Pouches

Different types of evidence support the scientific theory of evolution. The diagrams below show the skeleton of two different animal species. How does comparing the skeletons of these animals provide support for the scientific theory of evolution?

• It provides information about the organisms’ habitats
• It provides information to determine the organisms’ age.
• It shows possible common ancestry between organisms
• It shows possible chromosomal similarities between organisms.
