DT: How do you get from no wings to wings by Darwin's theory? - You are getting to sound more and more like a creationist! It seems perfectly possible to get from no wings to wings in small steps. In the case of wings on birds it is evident from the bone structure that they developed from limbs and hands. Flight with flapping wings can be reached via a gliding stage. - Wings on insects of course are a different kind of structure. Acording to P. Z. Myers they evolved from gills (I didn't even know insects had gills!): - http://pharyngula.org/index/weblog/comments/flap_those_gills_and_fly/ - In the case of the whale evolution we were discussing earlier. I don't see where your "macro-evolution" is necessary. The processes involved are smooth transformations like stretching or contracting or deforming. There is no evidence for any part of this process happening suddenly.
