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

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 ...

Chickens that were allowed to hatch had patchy feathers, with some naked spots and other places where soft, down-like ...

Scientists have successfully genetically modified chickens to make their feathers ... scientists were able to temporarily interfere with feather formation, revealing its importance in evolution. The ...

As part of their study of feather evolution, scientists have tried to restore the original ... Michelle Milinkovic The fact that the researchers failed to produce chickens with full plumage like ...

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