Biological Evidence of Evolution

Using DNA to determine which organisms are related to others is called:

• Homologous Chromosomes

• Molecular Biology

• Vestigial Structures

• Pharyngeal pouches

Organisms that have the most DNA sequences in common

• have the same number of legs

• Are the least related

• are randomly distributed

• Are the most related

A structure that serves the same purpose, but is not made in the same way is called

• a vestigial structure

• a homologous structure

• an analogous Structure

• a pheryngial structure

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
