Document Summary

Cuvier: father of paleontology: function defines form; no evidence of change overtime, established extinction as a fact. Lamarck: inheritance of acquired characteristics: use and disuse drive evolution and perfection. Hutton: gradualism: gradual change over long periods of time (slow) Lyle: uniformitarianism: present is key to understanding past, mechanisms of change are constant and uniform. These arguments allowed darwin to derive natural selection: the process in which individuals with favorable inherited traits are more likely to reproduce and survive passing on their traits to their offspring. Influenced by competition: fitness of a phenotype dependent on the frequency to other phenotypes in a given population. Darwinian fitness (survival of the fittest): the ability to survive and reproduce to pass on genes to viable and fertile offspring: surviving to reproducing age, mating success, fecundity: the number of offspring, offspring survive to reproducing age. Meiosis: gametes are created to produce 4 daughter cells, haploid (n)
