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

In a nutshell Scientists temporarily reversed feather evolution in chickens by blocking a key developmental pathway, causing ...

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

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

While a transient over-expression of the gene can permanently turn feet scales into feathers, it is much harder to disrupt ...

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

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.

Feathers are among the most complex cutaneous appendages in the animal kingdom. While their evolutionary origin has been ...

As part of their study of feather evolution, scientists have tried to restore the original appearance of chickens. They succeeded, but only temporarily. By inhibiting the key gene Sonic Hedgehog at ...

Researchers had previously altered the same gene to turn scaly chicken feet feathery, but turning back the clock on feather evolution proved harder. "Our experiments show that while a transient ...
