Document Summary
Understanding the living world: plato, idealism, aristotle, evidence of design/purpose in nature (teleology, theophrastus, father of taxonomy. Linnaeus: humans are part of nature, species may change through time, by hybridization, such events are divinely inspired. Lamarck (france: didn"t understand genetics yet, theory of inheritance of acquired characteristics, thought things loss/gained traits based on use/disuse. Scala naturae: rocks/dirt trees/plants animals humans. Erasmus darwin: all living things descended from other living things. Believed mankind has a propensity to use abundance (of food, resources) to grow its population, rather than maintain a high standard of living: abundance of food population growth restores original per capita production level. Studied malthusian principle : populations have geometric/exponential growth will food production has only arithmetic growth. Reproductive ability tendency for geometric/exponential increases (malthusian) Environmental restrictions limited resources: not enough food for exponential growth to continue. Struggles for existence (competition: heritable variations, natural selection (persistence of adaption)
