Where is living proof of evolution like for instance a lizard with feathers but not yet completely a bird?

Answer 1

Most species that exist in competition with others for resources are all "living examples of evolution," since they're continuing to evolve. If you're looking for a creature that's halfway between two existing classes or families--such as a bird that's "turning into" a lizard, as you suggest--then I don't think you have a clear understanding of what evolution is, or how it works. Evolution is a change in genetics from one generation to another (mutation). Those changes accumulate depending on their effect on survival and reproduction (natural selection), eventually resulting in divergent genetic lines that wind up as different species. As more changes accumulate, differences can widen, moving the species even farther apart in size, appearance, appendages, specific organs, etc. To see observed instances of species divergence (or species 'creation', depending on your perspective), check out http://www.talkorigins.org/faqs/faq-speciation.html. I think that a good example of what your looking for may be found in the salamders and lung-fish. A lung-fish is a fish that has lung with which I can breath air. The hell-diver is a salamander with gills.
