Ancient Hox Gene Code Sheds Light on Evolution of Vertebrate Fins and Limbs

This research explores the genetic origins of paired appendages in vertebrates, focusing on the ancient Hox gene code that underlies the development of pectoral and pelvic fins in fishes and limbs in tetrapods. The findings provide insight into how the genetic system for building these appendages was assembled during vertebrate evolution, addressing a key unresolved question in evolutionary biology.
