What scientific proof lies behind evolution?
Homology and bio-chemical similarities are really the same argument. Both allege that similar features in different organisms are due to inheritance from a common ancestor. Evolutionists use a number of studies to identify matching traits. Homology examines similarities of bone structures from different animals. DNA hybridization evaluates the closeness of species relationship by how many DNA strands from different species can be matched. Electrophoritic analysis show the degree of similarity of proteins from different species. And protein sequencing measures the closeness of relationship by the amount of DNA coding change which is needed to produce the slightly different proteins of different species. One protein sequencing study, for instance, shows there is only one percent difference between chimpanzees and humans. Forelimbs are the most widely cited example of homology. You may have seen the drawings in school. A human arm is compared bone by bone with forelimbs of whales, dogs, b
