Vertebrate paired fins are specified by an ancient dorso-ventral patterning system
PLOS ·
The 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.

by Rebecca E. Dale, Silke Berger, Sara Alaei, Marcus C. Davis, Frank J. Tulenko, Peter D. Currie The origin of paired fins was a major event in early vertebrate history that fueled the adaptive radiation of the gnathostome clade. Evidence for the conservation of ancient…
