biogenesis

 [bi″o-jen´ĕ-sis]
the theory, opposed to spontaneous generation, that living matter always arises by the agency of preexisting living matter.

bi·o·gen·e·sis

(bī'ō-jen'ĕ-sis),
1. Term given by Huxley to the principle that life originates from preexisting life only and never from nonliving material.
2. Synonym(s): biosynthesis
3. The principle that a living organism can only originate from a living organism similar to itself.
[bio- + G. genesis, origin]

biogenesis

/bio·gen·e·sis/ (-jen´ĕ-sis)
1. origin of life, or of living organisms.
2. the theory that living organisms originate only from other living organisms.

biogenesis

(bī′ō-jĕn′ĭ-sĭs) also

biogeny

(bī-ŏj′ə-nē)
n.
1. The principle that living organisms develop only from other living organisms and not from nonliving matter.
2. Generation of living organisms from other living organisms.
4. The supposed recurrence of the evolutionary stages of a species during the embryonic development and differentiation of a member of that species. Also called recapitulation.

biogenesis

[bī′ōjen′əsis]
Etymology: Gk, bios + genein, to produce
1 also called biogeny [bī·oj'ənē] , the doctrine that living material can originate only from preexisting life and not from inanimate matter.
2 the origin of life; ontogeny and phylogeny. Compare abiogenesis. biogenetic, adj.

biogenesis

A term of waning popularity that specifies what is now regarded as an inherent scientific truism—i.e., that all life arises from pre-existing life; this in contradistinction to spontaneous generation of life (life arising from non-pre-existing life).

bi·o·gen·e·sis

(bī'ō-jen'ĕ-sis)
1. Term given by T.H. Huxley to the principle that life originates only from preexisting life and never from nonliving material.
See: spontaneous generation, recapitulation theory
2. Synonym(s): biosynthesis.
[bio- + G. genesis, origin]

biogenesis

The recognition that complex living organisms arise only from other living organisms and do not originate by spontaneous generation, as was once believed.

biogenesis

the principle that life is propagated only by existing life, rather than by SPONTANEOUS GENERATION. The principle's original formulation was that organisms are able to generate only other forms similar to themselves, but where ALTERNATION OF GENERATIONS occurs the statement is not entirely true; biogenesis has thus come to mean that a species gives rise only to similar forms and these forms can only be derived from parents which are similar.
