a term introduced by the German zoologist A. Weismann to designate the body of an organism, in contrast to the germ plasm, that is transmitted from generation to generation through the sex cells (seeGERM TRACK). Weismann maintained that the soma could not affect the characteristics of the germ plasm. The differentiation of an organism into soma and germ plasm (the hereditary substance) proves that it is impossible to inherit characteristics acquired as a result of environmental conditions during an organism’s development (seeACQUIRED CHARACTER). The adjective “somatic” is used to indicate physical phenomena as opposed to phenomena of a psychological nature.
