That's dishonesty.Mutation and natural selection don't know that, so some mutations (the same imaginary ones that turned fins into legs) will turn the upper fin into legs as well, then it will take millions of years till natural selection deselect them!Quote:it doesn't matter if some are asymmetrical either from inside or outside,
Evolution cannot explain this, because asymmetrical is not a disadvantage.
While minor symmetry is not an advantage as well.
[quote][quote]I mean total nonsense, for example fish with a third leg on their back, you claim that fins started to grow into legs, why only the two bottom ones?
Because dorsal fins are generally used for stability and not propulsion, as the lower fins are. There are exceptions like the Sunfish, but in most species of fish the dorsal fin isn't a limb.
Quote:You're looking for redundant limbs, which would, in fact, be disadvantageous in most cases just by dint of being additional matter that does nothing; it's a slight downward pressure, but having an additional leg in a place where it can't assist in locomotion means you're dragging around an essentially useless piece of flesh that weighs you down, catches on things etc etc.
