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

In a nutshell Scientists temporarily reversed feather evolution in chickens by blocking a key developmental pathway, causing the embryos to grow simplified, unbranched feather structures resembling ...

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 ...

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 ...

Duonychus tsogtbaatari, a feathered, two-legged dinosaur, was discovered in Mongolia. Its unusual anatomy and remarkably well-preserved claws have attracted scientists' interest. The dinosaur had ...

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 ...

A new analysis of a fossil found in 1889 has unveiled the presence of zeolites—and an entirely new mineralization method.

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 ...

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.
