For example, amino acids are an example of how every living thing on earth is related. Every type of protein in every living thing is made up of the same 20 kinds of amino acids. This is true in both prokaryotic and eukaryotic cells, showing the relationship between single celled organisms (bacteria) and multi-cellular organisms (animals), which supports evolution's idea that we evolved from single celled organisms. Another example of the unity of all living things is anatomical structure. Many animals share the same types of body and bone structures, which could only mean that they inherited it from a common ancestor. A specific example of this would be the bones in human’s arms, specifically the humerus, radius and the ulna. The forelegs of cats and dogs, the flippers on whales, and the wings of birds all share these exact same bones. This would lead us to assume that they either inherited this from a common ancestor or developed them through a similar process, both supporting the theory of …show more content…
evolution, and of course there are still gaps on both sides of the argument, but when you look at the scientific evidence supporting evolution compared to that of creationism, it is clear which theory has the advantage of proof on its side. Forty percent of Americans today believe in evolution, and thirty-nine percent in creationism. The other twenty-one percent are unsure, or believe that evolution occurs, but is guided by a supreme being. What with all the evidence to support evolution, and with discoveries still being made about it, helping to prove its legitimacy, maybe more people will believe in evolution in years to come, and not regard it as a theory but as an accepted
