See also:GENERATION (from See also:Lat. generare, to beget, procreate; genus, stock, See also:race) , the See also:act of procreation or begetting, hence any one of the various methods by which See also:plants, animals or substances are produced. As applied to the result of procreation, " generation " is used of the offspring of the same parents, taken as one degree in descent from a See also:common ancestor, or, widely, of the See also:body of living persons See also:born at or near the same See also:time; thus the word is also used of the See also:age or See also:period of a generation, usually taken as about See also:thirty years, or three generations to a See also:century. As a See also:term in See also:biology or See also:physiology, generation is synonymous with the Gr. Otoyiveves and the Ger. Zeugung, and may comprehend the whole See also:history of the first origin and continued See also:reproduction of living bodies, whether plants or animals; but it is frequently restricted to the sexual reproduction of animals. The subject may be divided into the following branches, viz.: (I) the first origin of See also:life and living beings, (2) non-sexual or agamic reproduction, and (3) gamic or sexual reproduction. For the first two of these topics see See also:ABIOGENESIS, See also:BIOGENESIS and BIOLOGY; for the third and more extensive See also:division, including (I) the formation and fecundation of the ovum, and (2) the development of the embryo in different animals, see REPRODUCTION and See also:EMBRYOLOGY.
