another problem i see is when finally given enough naughts to validate and make this theory plausable,not only at the same time, but in the same actaul area,you would have to have had two human beings evolve to sexual maturity at exactly the same time,but not only that,evolve and be two differant sexes
and this goes for every living thing,takes way to much theorising for me,to be a valid scientific arguemnet
