And when it worked, as with all successful inventions, it caught on..-You are now anthropomorphizing crows! One lucky crow guy discovers a trick for tool use. Does he tell the others about it or do they fly around watching him and learn the trick as us flightless humans do? The research fellow knows the crows are smart which is why he studies them. His point was the other birds get by without this style of beak, so why did it appear? My answer, the innate drive to complexity we see in evolution, something Denton comments about in his book, I've just found.
