Evolution as Fact and Theory- Fact: observation that has been repeatedly confirmed; can be overturned (observation of changes in gene) Theory: highly probable, well-tested and substained explanation of a natural phenomenon based on a large collection of observations (explanation of changes) Scala Naturae- great chain of being; God’s hierarchal structure of universe; goes from rocks to angels; Devil at bottom God at top; everything fits in somewhere and gives meaning to universe. Scientific Revolution- rejection of classical ideas for more mechanistic view of nature Darwin’s 4 postulates- 1. individuals within populations are variable 2. variations among individuals are heritable 3. in every generation, some individuals are more successful at surviving and reproducing than others- adaptations are traits that increase fitness 4. survival and reproduction are nonrandom Testability of Evolution- Does beak shape vary? Is beak shape passed from parent to offspring? If every individual survives will there be increase in pop? Did some variants of beak depth survive drought?
