The Aldabra Rail supposedly evolved flight and lost flight…3 TIMES???
Check it out here: “that loss of flight happened at least three times in the white-throated rail. The same kind of change happening in an organism, with the same result, is called “iterative evolution”. The probability of the same organ being affected on different occasions over tens to hundreds of thousands of years in the same species is very small indeed. The question also arises as to why the wings of these birds did not evolve into useful appendages, such as grasping arms?
But on the other hand (pun not intended), it is ordinarily said that the same evolutionary trajectory cannot repeat itself, much less reverse itself and happen again. This last rule is known as Dollo’s law of irreversibility.4 The fact that flight has been lost several times contradicts Dollo’s law. It also shows that is why it is absurd to say that these species of bird “came back from the dead”.”
