Just ran on Panda's Thumb: "Building Bridges [between Science and Religion] That Can Bear Scientific Scrutiny," by Jamie Jensen, a biology prof at BYU and self-described member of a "conservative Christian religion." Lots of good insight, good comments.

I just posted a short article on The Panda's Thumb, musing upon the book On Being Certain: Believing You Are Right Even When You're Not, by Robert Burton. Burton argues that we have an innate (and italicized) *feeling of knowing* that can lead us astray if we are not careful.

Just posted Human and Chimpanzee: 15% or 1% Genetic Difference? How Creationism Misleads the Public, by Martin Neukamm. pandasthumb.org/archives/202... As a commenter noted, dishonestly cropping a figure to make a point should have destroyed Luskin's credibility. It will not.

Astonishingly, 1 USian in 4 rejects evolution and so much modern science. The Scopes trial did not defeat creationism; it drove it dormant for a while. See my precis here pandasthumb.org/archives/202... and also a full post by William Trollinger and Susan Trollinger linked in the text.
