I. Evidence for evolution [REQUIRED READING]- Extant organisms
B. Mimicry and protective coloration- examples of adaptive evolution brought about by natural selection
2. One type of mimicry [REQUIRED READING - Be sure to pull down page to Monarchs and Viceroys]- a harmless species resembles one that is dangerous or distasteful
C. Developmental biology (looks at organisms from early embryos to adults)
D. Biogeography- the unequal distribution of organisms on the earth
4. The portion of the earth over which an organism is found is its range
5. Example of biogeographic evidence- plants and animals of the Galapagos
Islands (volcanic, formed recently)
c. Explanation- some neighboring organisms migrated or were carried to the island; here they subsequently evolved into new species (in response to different selective pressures here than on mainland)
E. Biochemistry and molecular biology
3. Because genes code for all the chemicals we make, a similar line of reasoning applies to proteins and other compounds
II. Evidence for evolution- Fossil organisms
