REVIEW FOR QUIZ TO ADD POINTS TO EVOLUTION GRADE

\SCI.9-12.B [Indicator] - Summarize the process of natural selection.

*Darwin’s 5 points 1.Population has variations. 2.Some variations are favorable. 3.More offspring are produced than survive 4.Those that survive have favorable traits. 5.A population will change over time.

*Evidence of Evolution 1. Biogeography: Geographical distribution of species. EX. Most marsupials live in Australia. 2. Fossil Record: Fossils and the order in which they appear in layers of sedimentary rock tells us the order that they appeared on earth (strongest evidence).

*Evidence of Evolution 3. Taxonomy: Classification of life forms. 4. Anatomy: Structures that are similar because of common ancestry (comparative anatomy) Structures that are similar because of common ancestry (comparative anatomy) Vestigial structures (remnant or leftover) structures that now have no function (human appendix) Vestigial structures (remnant or leftover) structures that now have no function (human appendix)

6 Homologous Structures

SCI.9-12.B [Indicator] - Exemplify scientific evidence in the fields of anatomy, embryology, biochemistry, and paleontology that underlies the theory of biological evolution.

*Evidence of Evolution *Evidence of Evolution 5. Comparative embryology: During the early development of organisms very similar structures appear in different organisms. Ex. At one point, humans have gill slits and webbed fingers. 6. Molecular biology: DNA and proteins (amino acids) cow insulin was once used to treat humans with diabetics

9 Evidence for Evolution - Comparative Embryology Similarities In Embryonic Development

Modes of Action Natural selectionthree modes Natural selection has three modes of action: 1.Stabilizing selection 2.Directional selection 3.Diversifying selection Number of Individuals Size of individuals Small Large

1.Stabilizing Selection Actsextremesfavorsintermediate Acts upon extremes and favors the intermediate. Number of Individuals Size of individuals Small Large

2.Directional Selection Favorsone extreme Favors variants of one extreme. Number of Individuals Size of individuals Small Large

3.Diversifying Selection Favorsopposite extremes Favors variants of opposite extremes. Number of Individuals Size of individuals Small Large
