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

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

Proto-feathers are simple, cylindrical filaments. They differ from modern feathers by the absence of barbs and barbules, and by the lack of a follicle -- an invagination at their base.

Understanding these genetic interactions is crucial for unraveling how morphological novelties like proto-feathers emerged ...

At the 12th day of incubation, feather buds exhibit longitudinal domains of cell density that correspond to the barbs of the future down feather. Feathers are among the most complex cutaneous ...

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

Birds are often associated with flight, but not all of them take to the skies. Around 60 species — fewer than 1% of all bird ...

Des scientifiques de l’UNIGE révèlent le rôle clé de certains gènes dans le développement des plumes, fournissant des indices sur leur évolution depuis les dinosaures.

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

The team successfully transformed scales into feathers They did the tests on chicken embryos by stimulating this pathway The saw the formation of unbranched buds resembling early proto-feathers ...
