New Study Reveals Evolution Does Not Have a Weak Foundation: It Has NO Foundation.

by Jerry Bergman, PhD

A new review article by Vivian Callier in Quanta Magazine reveals that evolution does not have a weak foundation: It has no foundation.[1] The subtitle summarizes the dilemma evolutionists are in: “For 50 years, evolutionary theory has emphasized the importance of neutral mutations over adaptive ones in DNA. Real genomic data challenge that assumption.”

Classical Darwinian or “Adaptationist” Evolutionism

In a nutshell, evolution theory has historically postulated that the source of genetic variety is created by genetic mutations which in turn are selected by natural selection. Improvements in a life-form that enable it to out-compete other life forms are more likely to survive and out-produce its competitors, thus maintaining or improving its position in its ecological niche. Those life-forms that are less able to compete are more apt to go extinct. This is the source of the expression, ‘survival of the fittest.’ As explained by Darwin, whose

core insight was that organisms with disadvantageous traits would slowly be weeded out through negative (or purifying) selection, while those with advantageous features would reproduce more often and pass those features on to the next generation (positive selection). Selection would help to spread and refine those valuable traits. For most of the first half of the 20th century, population geneticists largely attributed genetic differences between populations and species to adaptation through positive selection.[2]

Then, as more research was completed, it was realized this straightforward core of evolution was contradicted by much contrary evidence. One problem has always been the fact that the vast majority of mutations are deleterious, or nearly neutral. Mildly-deleterious or near-neutral mutations individually cause only minor or no problems, but they add up, in time producing genetic meltdown, causing death and eventually extinction.[3]
