Genetic Entropy Confirmed
June 5, 2011
In Darwinian evolution, variations must add new information to produce innovations. Neo-Darwinism ascribes those variations to genetic mutations. In 2005, geneticist John Sanford (Cornell) argued that the accumulation of mutations always decreases fitness in a process he called “genetic entropy.” The downhill trend is amplified by a number of factors, including selection interference and epistasis (interactions between mutations). Now, genetic entropy from epistasis has received support by two new papers in Science.
