I've been wondering lately how evolution manages to producecomplex organs. It is pretty obvious to me how evolution wouldselect some minor traits like size, resistnce to illness orclimate. There is a mutation where some organisms are slightlydifferent and better traits are selected. However I cannot imaginehow an organism will mutate to have lets say lungs at once andunless organism has a functional organ there is no reason for thetrait to be selected. So how does evolution produce complxorgans?
