Charles darwin, 150 anniversary of origin of species, 200 from his birth: evolution the central unifying concept of biology, development of darwin"s idea, evolution facts and fiction. Living things change gradually from one form into another over time. Changing universe replaced view of a static world. Evolution has no purpose; blind mechanistic process; just happens, not for anything. Jean-baptiste de lamarck, 1744-1829: 1st to use the term evolution, a pioneer, overthrew the idea of creation; got the mechanism wrong: the inheritance of acquired characters; never did experiments, just made observation. Every organism on earth is in linear track to get more complex. Individuals do not evolve theory of evolution; individuals genetics is fixed, but population genetics changes. August weisman: info passes only through germ cells, therefore, genetic info cannot pass from soma to gemetes and onto next generation; not reversible process. Alfred russell wallace & darwin: wallace was amazing collector, wrote a manuscript and sent it to.
