Abstract

A mutation is a DNA change that is recorded durably and passed on to the offspring. A number of mutations in germ cells have detrimental effects for they often cause hereditary diseases. Likewise, mutations that accumulate in body cells can generate cancers. Nevertheless, a large number of mutations are neutral in their normal environment. The few advantageous mutations that occur are generally maintained. Mutations that arise at random are constantly sifted through by a selective environment. This dual process works as the driving force of evolution.
