Stu (I presume), perhaps you should read your own posts before you send them.

If the EvolutionMegaLab was the best thing about that course, it must have been bad indeed. My experience with the OU was highly satisfactory and much more scientifically rigorous.

Did you expect too see rampant speciation in that time?
No. That's rather the point and why I find their claim that "you can see evolution in your own back yard?" to be somewhat overblown; a claim that you repeated when you posted it.

Do you know the rate of speciation of Cepaea? This is what they're trying to find out.
No they aren't. Nowhere near it. They are trying to find the changes in distribution of the various forms and whether they correlate with other factors.

I had never come across the Coalition of Scientific Societies before but judging by their member organisations, they carry a substantial amount of prestige. If they think "scientific concept" is a meaningful thing to say, I don't think your in a position to say it's "Wayyyyyyy too fuzzy.". It might be worth your while making the effort to understand.

I think Evolution (as a necessary precursor to Darwin's Natural Selection) would be considered a theory if it had not developed (evolved?) over a period of time through many great thinkers. I think you should read Darwin's "An Historical Note". It's only nine pages in the Penguin Classics edition of The Origin of Species.

I don't take much notice of anything pete says.
