- Reproduction varies from fusion of identical cells ( isogamy ) to fertilization of a large non-motile cell by a smaller motile one ( oogamy ).
- Sexual reproduction varies from isogamy ( both genders produce flagellate gametes of equal size ) to oogamy ( one gender produces a much larger, non-motile gamete ).
- There is then a relatively sound theory base for understanding this fundamental transition from isogamy to anisogamy in the evolution of reproduction, which is predicted to be associated with the transition to multicellularity.
- As early as 1803 Jean Pierre �tienne Vaucher had published on the isogamy ( sexual conjugation ) in the algae, but it was in the early 20th century that reproduction and development began to be extensively studied.
