Chickens treated to inhibit the sonic hedgehog (Shh) pathway during development grow feathers that resemble ancient ...

Scientists have successfully genetically modified chickens to make their feathers resemble those of dinosaurs. This study is part of a broader effort to understand how and why feathers evolved.

originate from simple appendages known as proto-feathers, which were present in certain dinosaurs.By studying embryonic development of the chicken, researchers from the University of Geneva (UNIGE ...

GENEVA — From dinosaur fuzz to eagle wings, evolution spent over 100 million years perfecting the feather. Now, Swiss scientists have found a way to reverse this process in the lab, causing ...

Feathers are among the most complex cutaneous ... emerged around 200 million years ago in certain dinosaurs. Paleontologists continue to discuss the possibility of their even earlier presence ...

Recreating the first dinosaur proto-feathers ‘‘Since the Shh pathway plays a crucial role in feather development, we wanted to observe what happens when it is inhibited,’’ explains Rory ...

scientists have managed to make chicken feathers more similar to the tubular proto-feathers that probably first appeared in the ancestors of dinosaurs in the early Triassic period 250 million years ...

What do you get when you combine chicken embryos, a gene named after a video game character, and a couple of scientists? A brand-new study that’s confirmed a key element in feather evolution ...

From Dinosaurs to Birds: The Origins of Feather Formation Mar. 20, 2025 — Feathers, essential for thermoregulation, flight, and communication in birds, originate from simple appendages known as ...

Researchers inhibited a gene during embryonic development in chickens to see if it would make their feathers look like those of dinosaurs. Here, we see feather buds on the 12th day of incubation.

For the first time, paleontologists have identified cavities in the bones of a dinosaur from the Alvarezsauridae family. This finding sheds new light on the evolution of avian characteristics in these ...
