Re-Versed Lyrics Copyright © 1997 Nancy L. Mari "Evolution" (sung to the tune of "Revolution“ by The Beatles) You say believe in evolution - well, you know… You say believe in evolution - well, you know… It's a thought-provoking view I think it's a convolution, well, you know… Of what God had planned to do But when you say that there's no master plan I think you probably just don't understand Underneath there's gotta be design You think it's the explanation - well, you know… The reason we exist today It causes me some consternation, well, you know… That chance can be the only way But then you start talkin' about the natural laws How can chance possibly be their cause? Underneath there's gotta be design Underneath there's gotta be design… Underneath there's gotta be design…

Mutations (hence new varieties) do not arise because they are needed -- they arise by chance Mutations merely furnish random raw material for evolution, and rarely, if ever determine the course of the process Natural selection is the differential reproduction of genotypes (genes) Evolution is the change in the genetic composition of a population over time – “Natural Selection is not Evolution” – Ronald Fisher, The Genetical Theory of Natural Selection An Evolution by Natural Selection Primer

Chapter VI …Organs of extreme perfection and complication. -- To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree. Yet reason tells me, that if numerous gradations from a perfect and complex eye to one very imperfect and simple, each grade being useful to its possessor, can be shown to exist; if further, the eye does vary ever so slightly, and the variations be inherited, which is certainly the case; and if any variation or modification in the organ be ever useful to an animal under changing conditions of life, then the difficulty of believing that a perfect and complex eye could be formed by natural selection, though insuperable by our imagination, can hardly be considered real. … Chapter VI …Organs of extreme perfection and complication. -- To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, abserd in the highest possible degree.
