Presentation Transcript
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.
