Within various species, we find multiple different DNA patterns in multiple different species that equate with the same job or the same over all design, that many people assumed they were commonly related until they had a DNA test done to them. If this is the case, why do we also see species with DNA very very similar to ours in which we can trace a common ancestor back to? Evolution has an ancestor. Common ancestry occurs. Mutations occur. Changes in genetic structure occurs and so you would expect a genetic cascading effect to occur. What also occurs, however, is that there are multiple ways to the same path so to speak. If the same environmental pressures befalls two distinctly different organisms, one would expect similar structures or homologous structures, albeit having different DNA patterns. From this DNA, we can determine a relatedness toward another branch however that may look entirely different from what that questionable species phenotype suggests. If we can find that this is much rarer than sharing a similar DNA with supposedly related organisms, then we can conclude that evolution is most likely our best bet for an answer. HOWEVER If we find out that most organisms have drastically different DNA and we have trouble placing them into genetic trees because of this, we should expect creationism to be the more likely answer. Guess which one molecular biology suggests?
