Although beneficial mutations are theoretically possible, [[natural selection]] does not act at the molecular level, but rather it operates only at the level of the [[organism]]. It selects only those mutations that produce a physiological change, which alters the survival or reproductive rate of the organism. As such, for every rare beneficial mutation that might occur, countless numbers of harmful mutations are accumulating within the genome of the organism - producing what is known as a "mutation load". | Although beneficial mutations are theoretically possible, [[natural selection]] does not act at the molecular level, but rather it operates only at the level of the [[organism]]. It selects only those mutations (which work at the molecular level) that produce a physiological change, which alters the survival or reproductive rate of the organism in a favorable way.
