By end, species were “children in time”II. Lamarck 1744-1829A. Credited of first reasonable theory of organic evolution1. “Acquired characteristics”B. Couldn’t account for extinctionC. No way of knowing how acquired characteristics passed on to offspringIII. Cuvier 1769-1832A. Great comparative anatomistB. Thought organisms designed (by creator) as perfect functional wholesThese notes represent a detailed interpretation of the professor’s lecture.

HMS beagle 1831-18361. 5 year voyage 2. Surveying trip around the worldB. Why should South America have totally different animals?C. Why are there different animals just a few miles apart on opposite sides of the Isthmus of Panama?D. Galapagos Islands1. “Hot spot Islands”2. Archipelagos (strung out in almost a linear fashion)3. FinchesE. Oceanic Islands1. Island far from continents have no land mammals, toads and frogs; just bats2. Islands have their own speciesF. Down House Kent 1842 (onwards)G. 1844: theory of natural selection in draft formV. Alfred Russell Wallace1823-1913A. Writes to Darwin with Theory of Natural selection 1858 B. Co-discoverers of the Theory of Natural SelectionC. Darwin’s and Wallace’s papers presented jointly to the Linnaean Society 1858D. The Origin of Species 1859VI. Theory of Natural SelectionA. Many more organisms are born than can survive (competition)B. Variation in behavior and morphology1. MUTATIONC. variation is linked to fitness (in the environment)D. fitness is tested by competitionE. Better variants “win” and poorer ones don’tVII. Natural SelectionA. Most features can be inheritedB. Within a population of organisms, there is variations in inheritable featureC. This variation leads to differing rates of survival and reproductive successD. Differential survival and reproduction leads to a shift in the frequency of charactersE. After enough time, parent and daughter species can’t interbreedF. Process of SPECIATIONVIII. EvolutionA. Genetic change of a population of organisms over time, produced by the effects of natural selection on variation within a
