Scientists uncovered a key genetic pathway in the origin of feathers, but they found that evolution is stubborn in turning back the clock.

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 ...

From two weeks onwards, feather development in the embryos partially returned to normal. The chicks with the altered pathway ...

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

While a transient over-expression of the gene can permanently turn feet scales into feathers, it is much harder to disrupt feather development itself. The network of interacting genes determining ...

Kitsap County Sheriff’s Office helped settle some ruffled feathers over the weekend, after a woman said her ex-boyfriend ...

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

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

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.
