EVOLUTION (by: Jonah Pearce, Lillie Chapin, Kim Brunney)

  • (Evolution) Linnaeus

    (Evolution) Linnaeus
    Linnaeus divided life into catgories and subcategories, a precursor to Darwin's Tree of Life. Linnaeus sperated life into kongdoms, classes, orders, genera, and species. Linnaeus, however, believed that each living thing was not the effect of evolution, but was instead made by God's intent.

  • (Evolution) Comte De Buffon

    (Evolution) Comte De Buffon
    Comte De Buffon was a proponent of the idea that living creatures evolve according to natural laws-not by an act of God. De Buffon also suggested that humans and apes were related, and that all life came from a single ancestor. He was later forced to recant.

  • (Evolution) Cuvier [IF HE'D KNOWN]

    (Evolution) Cuvier [IF HE'D KNOWN]
    Cuvier attempted to explain mass extinctions by describing great floods and earthquakes. He also stated that life did not evolve into their present forms.

    Mendel publishes a paper showing how traits are passed down in "units". In the 1860's this discovery goes unnoticed.
  • (Evolution) Descent of Man [INFLUENTIAL]

    (Evolution) Descent of Man [INFLUENTIAL]
    Darwin's new book stresses the importance of "sexual selection". To pass traits on you must be fit to survive and irresistible to the opposite sex.
  • (Evolution) Horse Fossils [IF HE'D KNOWN]

  • (Evolution) NeoDarwinism [IF HE'D KNOWN]

    (Evolution) NeoDarwinism [IF HE'D KNOWN]
    Scientists determine that mutations cause changes in an organisms traits, spread through the population and affect natural selection. THis is the updated version of Darwins theory and explains the diversity in living things.
