2. Direct Evidence of Evolution - Fossils
Fossils provide the direct evidence of evolution. The direct evidence makes evolution a fact.
Some Types of Fossils: Preserved in amber or tar pits or frozen climates, imprints, bones, molds, casts
Fossils can reveal body structure, behavior and even movement
