microorganism

 [mi″kro-or´gah-nizm]
a microscopic organism; those of medical interest include bacteria, fungi, and protozoa. Viruses are often classified as microorganisms, although they are sometimes excluded because they are not cellular and they are unable to replicate without a host cell.

mi·cro·or·gan·ism

(mī'krō-ōr'gan-izm),
A microscopic organism (plant or animal).

microorganism

[-ôr′gəniz′əm]
Etymology: Gk, mikros + organon, instrument
any tiny, usually microscopic entity capable of carrying on living processes. It may be pathogenic. Kinds of microorganisms include bacteria, fungi, protozoan, and viruses.

microorganism

An organism detected by microscopy—e.g., viruses, bacteria, fungi and intracellular parasites (protozoans).

microorganism

(mī´krō ōr´gənizəm),
n a microscopic living organism, such as a bacterium, virus, rickettsia, yeast, or fungus. These may exist as part of the normal flora of the oral cavity without producing disease. With disturbance of the more or less balanced interrelationship among the organisms or between the organisms and host resistance, individual forms may overgrow and induce disease in the host's tissues. Those foreign to the individual may invade and produce pathologic processes.

a microscopic organism; those of veterinary interest include bacteria, rickettsiae, viruses, fungi and protozoa.

This is even more nonsensical than it sounds, because (as Ridley only partly acknowledges), all unicellular organisms and plants, many animal species and some mammals, have no separation of germ from soma plasma (Goodwin, How The Leopard Changed its Spots, 1994), but it is a good example of the quite bizarre scenarios that gene-centricism will yield when pressed to its logical conclusion.
It would seem that evolution should proceed much faster in multicellular than in unicellular organisms over a given number of generations because of this intermingling of generations because of this intermingling of genetic material.
