In recent decades biologists have discovered that organisms possess a variety of adaptation mechanisms far more sophisticated than ever imagined. Some of these mechanisms are regulatory in that they influence which genes are used at a given time. Other mechanisms change the genes themselves by mutating the DNA sequences. These adaptive mutations respond to the current environmental challenge and such findings contradict contemporary evolution’s view that mutations are blind to need and are preserved only by the action of natural selection. Now, new research suggests yet another adaptive mutation mechanism. Read more
