4) I have quoted uniformly similar definitions of NS from a large number of sources. Please provide a reference confirming your claim that “professional scientists” now reject the conventional Darwinian definition and adhere to your own, as above in 1).
The conventional Darwinian view was purely one that looked at life synonymously with geological processes. Slow. Gradual. We now know:
http://www.youtube.com/watch?v=YbcwDXhugjw In 3 generations, aggressive behavior started to disappear. By generation 50… we basically have small, cute, dogs.
http://www.jstor.org/pss/1383570  This paper discusses a speciation event that took less than 34 years to create.
http://www.livescience.com/3224-super-predators-humans-force-rapid-evolution-animals.html  Human involvement increases lifecycle rates by 300% in some animals.
The basics are still there: No evolution happens without pressure. However, Darwin’s understanding was on a geologic timescale, and modern understanding demonstrates that speciation can occur much more rapidly.

5) I have given you a point for point analysis of the beta-lactamase experiment which you regard as a perfect example of your definition. I have explained why I see it as a perfect example of Darwinian evolution. Please explain as briefly as possible why this is not an example of beneficial mutations surviving and flourishing, as per the Darwinian definition of Natural Selection.

The view I presented to you is a modification of Darwinian theory in the same way that Einstein’s theory of relativity was a modification of Newton’s theory. The basic equations are still valid, but the understanding and subsequent results are not. The view I discussed that I had learned while working in a laboratory is an extension and displacement, not a complete replacement of the original Darwinian Theory.
