All birds with webbed feet, for example, did not inherit that trait from a single evolutionary event. The webbing that allows some birds to swim so effectively "appeared more than once" in the evolutionary history of aquatic birds, Hedges says.The fact that an event that was thought to have occurred only once actually happened over and over again shows just how adaptable aquatic birds are, he adds, and it indicates that evolution could have moved along at a somewhat faster pace than had been thought.
