At first glance, feathers may seem like simple parts of a bird’s body. But if you look closer—under a microscope or through a scientific lens—they reveal an intricate story of evolution, biology, and ...

Feathers are among the most complex cutaneous appendages in the animal kingdom. While their evolutionary origin has been widely debated, paleontological discoveries and developmental biology studies ...

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 ...

When sea creatures first began crawling and slithering onto land about 385 million years ago, they carried with them their body armor: scales. Fossil evidence shows that the earliest land animals ...

Feathers are the essence of birds. Without them, birds could not fly or attract mates. But how exactly do feathers form molecularly? Experimentally testing one current hypothesis, developmental ...

These feathers got stuck in a glob of amber millions of years ago. Image credit: Science/AAAS Instead of digging through rocks and rubble to find fossils, a group of Canadian paleontologists decided ...
