Document Summary
Mechanisms of selection: reactions to origin of species publication. Wilberforce vs. thomas huxley, 1925 monkey trial : natural selection - recap. Survival of fittest (spencer) - misinterpretations and ensuing damage: mendel"s contribution. Problem of reappearance of traits in subsequent generations. Methodology - patterns of inheritance in pea plants that could be characterized in a binary fashion critical observations which laid foundation for science of genetics. 5 critical findings: the new synthesis - implications. Evolutionary change is transmitted by surviving genes, genes eye view variability among phenotypes attributable to variability in genotypes. formulation of testable hypotheses - top-down vs. bottom up strategies - examples. Top-down vs. bottom-up is not that one is better than another but rather complementary theories that together give a full picture. Ex. reverse engineering approach often used to examine evolutionary adaptiveness of sexual jealousy: sources of variation mutations. Causes, random changes, effects of mutations in gene frequencies over generations.
