Document Summary
Concept 22. 1: the darwinian revolution challenged traditional views of a young earth inhabited by unchanging species. Several philosophers suggested that life might have changed gradually over time. Aristotle(384-322 bce) = viewed species as fixed (unchanging) He concluded that life-forms could be arranged on a ladder, or scale, of. Ideas consisted of the old testament account of creation, which holds that increasing complexity, called scala naturae (scale of nature) species were individually created by god and therefore perfect. Carolus linnaeus(1707-1778)= developed the two-part, binomial, format for naming species. He adopted a nested classification system, grouping similar species into increasingly general categories. Darwin drew from the work of scientists studying fossils. May fossils are found in sedimentary rocks formed from the sand and mud that settle to the bottoms of seas, lakes, and swamps. Georges cuvier( 1769- 1832) = noted that the older the stratum, the more dissimilar its fossils were to the current life-forms.
