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

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

• Homologous Chromosomes

• Molecular Biology

• Vestigial Structures

• Pharyngeal pouches

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 in one organism that is similar in function with the body part of another is called a

• homologous structure

• analagous structure

• vestigial structure

• Pharyngial pouch

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

• Evolution

• Embryology

• Paleontology

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