Homology in Crisis As Mayr suggests, there are other examples where genetic similarity appears in unexpected places. Biologically functional similarity that is thought to be the result of inheritance from a common ancestor is called “homology.” The concept of “homology” has been thrown into a crisis via observations, like those of Mayr, that the same genes control the growth of non-homologous body parts. Pax-6 is just one example. Another is the fact that the same gene controls the development of limbs in Read More ›

Extreme Genetic Convergent Similarity: Common Design or Common Descent? If common descent is leading to so many bad predictions, why not consider the possibility that biological similarity is instead the result of common design? After all, designers regularly re-use parts, programs, or components that work in different designs (such as using wheels on both cars and airplanes, or keyboards on both computers and cell-phones). One data-point that might suggest common design rather than common descent is the gene “pax-6.” Pax-6 is one Read More ›

The Molecular Evidence When speaking to the public, evolutionists are infamous for overstating the evidence for universal common ancestry. For example, when speaking before the Texas State Board of Education in January, 2009, University of Texas evolutionist biologist David Hillis cited himself as one of the “world’s leading experts on the tree of life” and later told the Board that there is “overwhelming agreement correspondence as you go from protein to protein, DNA sequence to DNA sequence” when reconstructing evolutionary history using Read More ›

Evolutionists often claim that universal common ancestry and the “tree of life” are established facts. One recent opinion article in argued, “The evidence that all life, plants and animals, humans and fruit flies, evolved from a common ancestor by mutation and natural selection is beyond theory. It is a fact. Anyone who takes the time to read the evidence with an open mind will join scientists and the well-educated.”1 The take-home message is that if you doubt Darwin’s tree of life, you’re Read More ›
