von Neumann, as many of you presumably know, created working models of self-reproducing entities, which do so at random, asexually, in an agitated pea soup of spare parts.
Sequences like egg-chicken-egg (or, pace Gerhard, chicken-egg-chicken) have also been modeled, as have explicitly sexual ones. It is likely that a number of distinct, competitive processes have been at work for a very long time.
