@HexHammer,
Man shares a DNA signature with all organic life forms on earth, all separated by degrees. How could it be anything other considering that all life is constructed of the same basic elements that are common to our shared environment? This FACT demonstrates what exactly in proving or disproving the falsified theory of SPONTANEOUS GENERATION of life from dead matter, the basic tenet of VERTICAL EVOLUTION? Whenever and wherever this theory of Natural Vertical Evolution of life as being a product of generating from dead matter is placed to the test of the Scientific Method of Observed, Reproducible Experimentation it is falsified. There has not been one example of Observed or Reproduced vertical evolution (evolution outside of a preexisting species) where a NEW species has been observed developing from another species.
But, on the other hand the Law of Biogenesis is Observed and Reproduced in nature on a daily basis, with the fundamental declaration of that Reproducible experiment clearly evidenced, that being LIFE can only be PROCREATED from an existing life within the same species.
