((Some unicellular organisms have sexual reproduction. Besides, given the presence of complex organs like jaws, electric and other sensory organs, digestive glands, trunks, limbs, proboscises, spines, and apparently nervous systems, we don't seem to be so much "unicellular" as "plankton".))
((Can you provide an example of unicellular organisms that reproduce in such a manner?))
((
Lazy Answer.And I can't find the names of any specific species, sadly. I do, however, clearly reading about unicellular organisms (possibly prokaryotes rather than bacteria) combining, reproducing their DNA, and then dividing into four. Basically combining two germ cells and having the resulting cell undergo meiosis.))
((Besides, plankton can also be, and frequently is unicellular.))
((Many plankton are also larvae for crustaceans and the like. Should we assume that we'll grow into crabs?
Moreover, sea animals can be air-breathers; should we assume that we are?))
