New limbs from old fins, part 2

The second post in my series on limb evolution is now up at the BioLogos site. This installment reviews the fossil evidence on fin-to-limb evolution, introducing the famous Tiktaalik. Next up: evidence from developmental biology.

The first post at BioLogos outlined limb structure and some historical background. The series at BioLogos was spawned by an idea here at QoD, which aimed to discuss some new findings in the fins-to-limbs story. Those new findings will be discussed in the fifth installment of the series at BioLogos.
