   alternate generation biol., alternation of sexual with
      asexual generation, in which the products of one process
      differ from those of the other, -- a form of reproduction
      common both to animal and vegetable organisms. in the
      simplest form, the organism arising from sexual generation
      produces offspiring unlike itself, agamogenetically.
      these, however, in time acquire reproductive organs, and
      from their impregnated germs the original parent form is
      reproduced. in more complicated cases, the first series of
      organisms produced agamogenetically may give rise to
      others by a like process, and these in turn to still other
      generations. ultimately, however, a generation is formed
      which develops sexual organs, and the original form is
      reproduced.

   spontaneous generation biol., the fancied production of
      living organisms without previously existing parents from
      inorganic matter, or from decomposing organic matter, a
      notion which at one time had many supporters; abiogenesis.
