Feathers are complex skin structures, and their evolutionary beginnings are still a subject of scientific debate. Scientific ...

Scientists recreate ancient proto-feathers in chicken embryos, revealing evolutionary resilience in feather development.

Feathers may define birds today, but their story began millions of years ago in creatures that looked very different from ...

Feathers may have started as simple filaments in ancient dinosaurs, but a team of Swiss researchers is digging deep into the ...

But what happens when the Shh pathway is blocked instead? That’s what the research duo sought to find out in this new study. This involved injecting chicken embryos with a molecule that inhibits ...

Feathers, essential for thermoregulation, flight, and communication in birds, originate from simple appendages known as proto ...

Scientists now believe that feathers didn’t just appear suddenly in birds. Instead, they evolved step by step from much ...

The ability to turn off a gene of interest in a temporally and spatially controlled manner is key to the analysis of gene function in developing organisms. However, the induction of temporally ...

Understanding these genetic interactions is crucial for unraveling how morphological novelties like proto-feathers emerged ...

In a previous study, the Swiss scientists stimulated the Shh pathway by injecting an activating molecule into the blood vessels of chicken embryos and observed the complete and permanent ...
