New limbs from old fins, part 1

Last month, I started a series on the topic of limb evolution, here at Quintessence of Dust. That series has been transformed (through a series of intermediates) into a series of posts at the BioLogos site. The first installment is now up, and it provides an expanded introduction to the topic and a little historical context. Subsequent posts will tackle fossils, developmental biology, genetics, the explanatory role of design, and related themes.

So go check out the introduction, and feel free to contribute comments, questions and suggestions here. And enjoy the image below, from Wellcome Images, which is featured in the post at BioLogos. Cool, huh?
