<i>it is impossible for complex features such as wings, eyes etc to evolve because they will require a series of mutations that do not individually confer any evolutionary advantage</i><p>The answer to this proposition is that the fact we aren&#x27;t aware of the evolutionary advantages which were obtained en route doesn&#x27;t mean there weren&#x27;t any.<p>The feathered wing is very complex and it won&#x27;t fly until it has fully evolved, for example -- but as we learned quite recently, feathers evolved (and were an evolutionary advantage) because dinosaurs needed to stay warm.  Birds can fly because a feather which is efficient at capturing air and keeping a giant lizard warm also turns out to be very efficient at pushing air and keeping a proto-avian aloft.
