BIOL 1001 Chapter Notes - Chapter 3: Natural Selection, Internal Consistency, Rifampicin
Document Summary
Perfect world and our earth: everything present on earth is slightly different than the perfect type for that thing. These types are unchanging: this idea was known as typological thinking. Species are unchanging and their variations are unimportant. Aristotle"s great chain of being: species are fixed types, some species are more complex (better, higher up the chain) and some are less complex (lower down the chain) Lamarck"s idea of evolution change: ties to the great chain of being, he says that species start off at the bottom of the chain and move up the chain by evolving, species change through time by inheriting traits. They inherit these traits in order to adapt to certain environments. Darwin ad wallace"s evolution by natural selection: population thinking: The idea that there is a variation amongst individuals in a population. This idea overturned the idea of typological thinking with pop thinking. Says species are changing and evolving rather than staying the same.
