Debunking Corner : On the gain of genes and gene function

From Wonderful Life;


Michael Behe recently published a review article in the Quarterly Review of Biology entitled Experimental evolution, loss-of-function mutations, and “the first rule of adaptive evolution” (subscription required), which consists largely of a review of laboratory experiments addressing the adaptive response of microorganisms to simple environmental changes. Behe generates a new definition – Functional Coded elemenTs (FCTs), essentially any segment of DNA that has a biological function, and a “rule”, the “first rule of adaptive evolution”, which essentially states that the majority of adaptive changes reflect mutational events are those which impair or eliminate FCT function.
