The insane creatoid Peppered Moth Jihad is just bizarre. After all, creationists are the first to tell us they have no problem with natural selection, or with "microevolution," which is exactly what the Peppered Moth research reveals. So what's the deal? Especially when there's no "there" there. Kettlewell's research, and his full and honest reporting thereof, was exemplary, and later researchers have verified and extended his results.
Why the utterly gratuitous and shockingly dishonest smears when the underlying phenomena is one that creationists (supposedly) don't even take issue with???
The only reason I can come up with is that Jonathan Wells decided to publish these idiotic and dishonest smears in a popular antievolution book, and none of his fellow antievolutionists possess the intellectual honesty (or simple sense of shame) to stand up an correct the lies.
And, btw, in answer to the article's question, this kind of shameless intellectual dishonesty is exactly what "Darwinists are so afraid of".
Nobody of sound mind denies that natural selection happens but natural selection, in and of itself, is not a mechanism that moves evolutuion along it's merry way.
It's all about the benjamins and the mechanisms.
