Title: The Panda's Thumb (blog)
Passage: The Panda's Thumb is a weblog on the creation-evolution controversy from a mainstream scientific perspective.  In 2006, "Nature" listed it as one of the top five science blogs.  It is written by multiple contributors, including Wesley R. Elsberry, Paul R. Gross, Nick Matzke, PZ Myers and Mark Perakh, many of whom also have complementary weblogs at ScienceBlogs.  The blog takes its name from The Panda's Thumb, the pub of the virtual University of Ediacara, which is named after the by Stephen Jay Gould, which in turn takes its title from the essay "The Panda's Peculiar Thumb", which discusses the Panda's sesamoid bone, an example of convergent evolution.
