Evolution - a unifying principle 
              of biology 
            The theory of evolution states that 
              modern organisms are descendants of ancient organisms and that modifications 
              accumulated over time explain the apparent changes and differences 
              among modern forms of life. This 'descent with modification' theory 
              was central to Charles Darwin's argument of biological evolution, 
              an idea spearheaded by Jean-Baptiste Lamarck (1744-1829). The idea 
              of evolution proposes that animals and plants can change over time, 
              and are not static forms created at once and independent of each 
              other. Lamarck and Darwin proposed different explanation of how 
              these changes may occur. Darwin's proposal of natural selection 
              has proved correct and evidence from biology, earth science, and 
              cosmology all corroborate the basic mechanism of natural selection.
