## In brief

- A PLOS Biology paper titled "Vertebrate paired fins are specified by an ancient dorso-ventral patterning system" was published on 2026-11-10.
- The authors, led by Rebecca E. Dale with Peter D. Currie among them, study the origin of paired fins, a major event in early vertebrate history.
- The paper reports that paired fins are specified by an ancient dorso-ventral patterning system, according to its headline.

## Why it matters

It addresses how paired fins, a key innovation in early vertebrates, arose and how their developmental programme relates to ancient patterning systems, which informs understanding of gnathostome evolution.
