+548+. The "conceptional" theory refers the origin of totemism to the belief, found among certain peoples, that conception is produced by the entrance into the mother's womb of some object (animal, plant, or other) with which the child is identified.[904] In Central Australia it is held that what passes into the woman is a spirit child which has a certain object for its totem; but in this case the previous existence of the totem is assumed. In certain islands (Mota and Motlav) of the Banks group, however, there exists, it is said, the belief that a child is the object from which the mother received some influence at conception or at some other period of pregnancy--the child resembles the object, and may not eat it if it is edible.[905] The persons thus identified with a given object would, if united, constitute a group totemic in the respects that they believe themselves to be one with the object in question and refrain from eating it.[906] The totemic object is selected, in the case of every child, by the fancy of the mother, and is, therefore, not inherited; totemic groups, thus, would be found distributed through the larger groups (phratries or tribes), and might also gradually coalesce and form local groups. If the belief in this origin of birth (identity of the child with some object) were found to be widespread, and generally effective as the ground of early social organization, it would furnish a satisfactory explanation of totemistic beginnings. But in point of fact it has so far been found, in full form, only in a small region in Melanesia, and its history in this region is not known; back of it may lie some other system of organization. And in this region clan totemism is lacking or faint. Further testimony is needed before it can be accepted as the solution of the problem of totemic origins.[907]
