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

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 ...

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 ...

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

Inhibiting the sonic hedgehog (Shh) pathway strongly perturbs feather development in chickens by restricting feather bud ...

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

This research provides new insights into the morphogenetic mechanisms that led to feather diversification throughout evolution. Feathers, essential for thermoregulation, flight, and communication ...

The studies show that the Sonic Hedgehog gene has been involved both in the evolution of proto-feathers into today's feathers, as well as in the diversification of feathers into different shapes ...

The emergence of proto-feathers likely marked the first key step in feather evolution, initially providing thermal insulation and ornamentation before being progressively modified under natural ...
