Paul McBride believes (contra Ann Gauger and others) that common descent is a perfect nested functional hierarchy (NFH) of species that only Darwinian evolution can have produced.
I have always said that NFHs cannot arise bottom-up by chance and necessity from molecules. In fact, the sub-functions at any level cannot serve their parent function, because it doesn’t yet exist. Only top-down design can create a NFH, by creating at any level first the parent, then its sub-functions.
However Paul McBride, instead of just talking about it, can prove his claim by a computer simulation. I woill ease his job: instead of beginning from molecules, he can start from the “first complete software simulator of bacterial cell” and program the RM+NS code. He can run the simulation and show us that his tree of NFH of species arises by evolution…
…There is a reason why, despite of the power of software and hardware tools available today, evolutionists haven’t succeed so far to provide the least computer simulation of a real and functioning NFH generated by C&N.
