Where to publish critiques of creationist issues?

Assuming that your discoveries aren't original (if they are then they ought to be submitted ot the scientific press first), I think that one of the skeptical magazines like Skeptic or Skeptical Inquirer would be your best bet.

I don't know. It might be worth running your ideas past a biologist (perhaps P Z Myers of Paryngula and The Panda's Thumb), or asking on Usenet (possible talk.origins but sci.bio.evolution might be a better bet). You could also search the internet to see if anyone is putting similar ideas forward.Personally I think that ReMine's ideas have two major flaws - one is that there is no good estimate on the number of mutations required or even for the real substitution rate allowed (Haldane's calculations used estimates that seem to have been no more than educated guesses). The other is that Haldane's argument that simultaneous substitutions don't affect the rate doesn't appear to apply in cases of "soft selection".
