Weal we have no particular prized example of differentiation, but until then we can still guarantee nature will stay true to what works. It may be a different planet, but that don't mean their can't be similar designs to adapt to similar envirments. Only thing we can really guarantee won't be repeated twice is humanity. Nature may have been to weak to sort the gens needed to make that out of the gen pool for stronger more effective designs on earth, but that was due to a major catastrophe. On other planets only the strong would have continued on.
