Slide1Many types of evidence supportevolution

Slide2Observations provide evidence fortheories.  Theory— a widely accepted statement based on scientific evidence that helps explain and predict natural phenomena  Theory of Evolution— based on three sources of evidence:  Fossil  Biological  genetic

Slide3Fossil evidence supports evolution. Fossil evidence shows that 2 speciees with a common  ancestor  can develop differently.  Ancestor— a distant or early form of an organism from which later forms descend

Slide4Biological evidence supportsevolution.  Includes the structure and development of living things  Includes   vestigial organs  and similar structures with different functions  Vestigial organs— physical structures that are longer useful to a living organism, but may have existed as fully developed similar structures useful to a common ancestor (vestigial limb in a whale)

Slide5Biological evidence (continued) Different species share many   similar structures , but these have different functions, such as the forelimbs of a bat, gecko, lizard, or manatee.  Similarities is  embryonic development  also indicate  common ancestry .

Slide6Genetic development supportsevolution.  Similar organisms have very similar  genes ; less closely related organisms have genes that are easy to tell apart.  Organisms with similar  patterns of DNA also share common ancestors.
