blue eyes, new trait, becoming lactose tolerant etc. etc. is evolution.
"you don't believe there can be enough minute changes over time to account for the complexity required to add a new structure (like a wing from a limb)"
where do you think the "limb" itself came from? do you think it was always there or through changes it evolved to be a limb?
You can argue over the meaning of evolution if you want, bottom line for me is change is limited. We are not seeing the change required to account for the diversity or complexity of life on this planet in 5 billion years.
We have been culturing bacteria in labs for over 150 years. In this time we have had approx 4 million generations of bacteria. We have not seen any change to something else which must happen for evolution to explain what we have now.(Complex multi-celled organisms) At some point we have to go from single celled to multi-celled, then celled dedicated to a certain function. If we have had no such change in 4 million generations, how long is needed for a chimp like animal to turn into a human at 15 years per generation? 60 million years? What about 24 years per generation as we see now in chimps? 96 million years? We are already back into the Mesozoic era. Are there any fossils of a chimp like ancestor to be found?
I believe G-d created all living things after their kind. Any minute changes that have happened is part of the original design's ability to adapt. But this is limited. A cat cannot change into a dog no matter how much it needs to adapt. This is called extinction.
