Document Summary
Evolution: decent with modification (changes in inheritable characteristics in a population over time) All organisms are: related by common ancestry (decent from ancestors, adapted to their local environment (modification by natural selection) Evolution : descent with modification: all life forms are related by common ancestry (not an original contribution of darwin, natural selection: process that explains diversity, complexity and fit" between form, function, and environment. Aristotle (384-322): scala naturae, which had a latter structure. Linnaeus adopted the ancient view that when classifying diversity: he is the founder of taxonomy, the branch of biology concerned with naming and classifying organisms. George cuvier: found evidence of change over time by looking at fossils in sedimentary rock. Proposed theory of catastrophism, which was later challenged by hutton and lyell who believed in gradual change or gradualism. Lamarck: evolution occurs by inheritance of acquired characteristics (wrong mechanism) giraffe neck example. Before c 1750: each species created separately by a supernatural agent.
