evolution - decent with modification; change in in genetic composition of a population from generation to generation fossils - the remains or traces of organisms from the past strata (stratum= singular) - superimposed layers of rock paleontology - study of fossils- developed by Cuvier adaptations - inherited characteristics of organisms that enhance their survival and reproduction in specific enviroments natural selection - process in which individuals that have certain inherited traits t...

Graudualism the view that Earth and its living systems changed slowly over its history Lyell Charles Darwin read Lyell's book and was much influenced by Lyell's Principles of Geology. He believes that evidence of the forces of geological change that have been shaping Earth for millennia is observable today (uniformitarianism) Lamarck a person who hypothesized wrong mechanisms for evolution and made contributions to evolutionary thought that species change with time and pass on changes e...

Cell theory - Answer all organisms are made of cells and all cells come from pre-existing cells Louis Pasteur - Answer designed an experiment to test if cells arose spontaneously or if they were the result of pre-existing cells Evolution - Answer postulates that (a) species are related to one another by common ancestry and (b) species can change through time from generation to generation. Natural selection - Answer process that explains how evolution occurs Fitness - Answer the abil...
