Why Darwin Matters ~ Michael Shermer
As a historical science, evolution is confirmed by the fact that so many independent lines of evidence converge to its single conclusion. Independent sets of data from geology, paleontology, botany, zoology, herpetology, entomology, biogeography, comparative anatomy and physiology, genetics and population genetics, and many other sciences each point to the conclusion that life evolved. This is a convergence of evidence. Creationists can demand “just not proved through a single fossil. It is proved through a convergence of fossils, along with a convergence of genetic comparisons between species, and a convergence of anatomical and physiological comparisons between species, and many other lines of inquiry.
