We are constantly told that evolution can build the genome over time, through chance mutations favored by natural selection. But what if this claim is false? What if the genome is not improving? What if, instead, it is actually degrading over time? Further, what if the scientific community has known this for decades and refuses to acknowledge it because of the damage it would do to evolution? Welcome to the premise of Dr. John Sanford’s book, Genetic Entropy. In the book, Sanford, a former evolutionist and emeritus professor at Cornell University looks at whether evolution, the “primary axiom” as he terms it, can work, using population genetics.
