Rates of Change

Match the following groups to the picture that describes they type of evidence that leads to common ancestry.

• Vestigial Structures

• Study of embryos. The early development the organisms look similar.

• Fossil

• A structure that is present that no longer serves its original purpose.

• Biogeography

• Structures in different species that have the same bone structure / different function.

• Homologous Structures

• Study of the distribution of organisms around the world.

• Embryology

• A trace of an ancient organism that has been preserved in rock.
