A critical question in biology is how new traits evolve, but studying this in wild animals remains challenging. Here, we probe the genetic basis of trait gain in sea robin fish, which have evolved specialized leg-like appendages for locomotion and digging along the ocean floor. We use genome sequencing, transcriptional profiling, and interspecific hybrid analysis to explore the molecular and developmental basis of leg formation.

- Scientists want to understand how animals develop new traits, both by losing old ones and gaining new ones.
- Sea robins, a type of fish, have grown new legs and special features in their brains to help them move.
- This study uses advanced techniques to discover the genes that help sea robins form their unique legs and shows how these traits differ between species of sea robins.
