By irreducibly complex I mean that the production of a particular function (in this case selectively advantageous propulsion by a rotating propellor of some kind) requires many specific simultaneous changes in 2 or more proteins such that it is unreasonable to think of them happening by chance.
I am interested to know whether any readers of this blog have read useful articles on the web which take the argument further.
I have looked at these:
1. Evolution in (Brownian) space:a model for the origin of the bacterial flagellum by N. J. Matzke 2. Mike Genes Series on Evolving the Bacterial Flagellum Through Mutation and Cooption
3. Ken Millers - The flagellum Unspun
4. William Dembski's Still Spinning just fine
If you have any suggestions please paste your link in a comment....many thanks!

Thanks Peter!
inunison: interesting article. I'm still trying to figure out what they mean by the idea that the Avida programmers assumed a pathway and that that led to the pathway existing. I'm probably misreading it, but surely if such a pathway couldn't exist then the algorithm wouldn't have "found" one? And if one could exist then doesn't that falsify the idea that irreducible complexity is unevolvable?
IC is a flawed concept anyway.
This might be interesting to read:
