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

Explore the fascinating world of dinosaur feathers and their evolution through groundbreaking research on chicken embryos.

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

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

Alteration of the expression of the co-called 'Sonic Hedgehog' gene can transform feet scale and wing feathers. While a transient over-expression of the gene can permanently turn feet scales into ...

Milinkovitch and Cooper had previously studied what happened when this pathway was stimulated in chickens, the result being embryos that developed feathered, rather than the usual scaly feet.

The Faverolles rooster looks like it belongs in a Victorian portrait with its fluffy beard and feathered feet. What’s even weirder is that most chickens have four toes, but this breed has five!

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

Cochin Bantams are smaller in size than standard chickens, but they still need adequate space to move around and exercise ...

Tweaking the Sonic Hedgehog gene can transform different aspects of development in chickens. For instance, transient over-expression of the gene can permanently turn feet scales into feathers. But ...
