How Do Fossils Show Change?

Most organisms live, die, and decompose. They leave no traces of having

lived. Under certain conditions, an organism’s remains or tracks may be preserved

as a fossil. Fossils give clues about how an organism looked and where it lived.

They are often used by scientists as evidence of change.

A fossil is any remains of a once living thing. Fossils may only be the outline

of some plant, animal, or other organism that is preserved in rock. Sometimes,

entire skeletons of animals that lived millions of years ago are found.
