Plant Sciences, Zoology & Evolution / Why don't evolving wings cause problems for a creature before being fully formed
« on: 12/03/2012 00:44:47 »
I understand the process of evolution and I do subscribe to the theory but there are some aspects of it I can't get my head around...
For example, how does a creature evolve wings and become able to fly when the wings will not function until they have completely evolved into a working wing. I can't imagine a creature loping around with half a (non functioning wing), when said stump would probably impede it's ability to survive and cause it's death before it has chance to procreate and spread the stump DNA down into the next generation.
There seem to be many things like this in nature that are too complex to have evolved in 'one step' but would almost certainly have caused problems for a creature before reaching a working stage of evolution.
Thanks in advance for your answers!
