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.
