Document Summary
Process occurring in present are same as in the past. Expanded age of the earth made evolution possible. Heritable variation + struggle for existence + differential reproduction = gradual change of population divergence + new species. Complexity on y axis and time on x axis. What was main contribution of linneus to biological thought. Still use it today as a classification system. Biologiocal taxonmomy, orderfing based on kingdom etc. Notable for heriracrhal classification natural class tries to find order to all that is observable. Do you take into account color of eyes. Come up with logical system cleary for our own purposes artificial classifaction. Based plants on sex organs our own purposes. Problem of natural class is too many varieties between species. Class plants based on sex animals very broadly based on visible characterisitic. Linneus naming sstem binomial nomenclature not first one to use this by using two names but first to standardize it.
