By comparing successive versions of Granville Sewell’s finite element program PDE2D (video here ), NCSE scientists have uncovered overwhelming evidence (from homology, etc.) that current versions evolved from a common ancester. The evidence is so overwhelming, in fact, that the competing theory of intelligent design has been abandoned by all serious scientists. “That Sewell’s software is the product of 35 years of evolution is now beyond debate,” said an NCSE spokesperson. “Only minor issues such as the mechanism of evolution are still being debated.”
(For a modest proposal on how the two competing theories might be reconciled, see this or this, or the video here.)
