Briefing: Fins, fingers and toes: A new take on repeating body parts and how they come to be

Andrew Gillis, an associate scientist at the Marine Biological Laboratory, has dedicated nearly 20 years to researching the evolution of paired fins in fishes. This extensive investigation aims to uncover the biological significance of repeating body parts.

The research focuses on the mechanisms that contribute to the development of paired fins, which are crucial for understanding evolutionary biology and the adaptation of marine life.

Gillis's work not only sheds light on the evolutionary pathways of fishes but also has broader implications for the study of body part repetition across different species.
