Bill , interesting you should use the word ...concept.....as until you are able to demonstrate that evolution of the microbes to mudcatters idea is true, it is merely a concept.   Am I getting it wrong and twisting that concept, I don't think so !   The concept does teach that over countless generations complete body plans change, does it not into vastly different organisms ? How many time have I been told that we got dinos on our bird table ?.       And science has not worked out anything , but scientists do make discoveries, and if more scientists than not interpret the data as evolutionism, that proves nothing other than that is the paradigm at present. Scientists are not impartial, as , IMO, the many recent discoveries illustrate. They point to a far more recent creation, but because the paradigm rules ,the evolutionists are searching for some way that the obvious conclusions from measured rates of decay can be disregarded or reinterpreted.
