New limbs from old fins, part 3

The third installment of my series at BioLogos is now up.* It discusses the developmental mechanisms that underlie the construction of limbs, and the striking fact that these mechanisms are the same ones used to construct fish fins. Watch for an appearance by Sonic Hedgehog.

*Edit July 2020: The series was consolidated into a single article on the BioLogos site. The link now goes to that single article.
