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 ...

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 ...

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 ...

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 ...

Feathers may define birds today, but their story began millions of years ago in creatures that looked very different from modern avians. A new study has just pushed the boundary of evolutionary ...

The growth of long facial feathers, creating the appearance of muffs and beards on chickens, is caused by a chromosomal rearrangement affecting a gene involved in feather development, researchers ...

Over the past decade and a half paleontologists have found the remains of numerous feathered dinosaurs, but, as announced in this week's edition of Nature, a new pair of specimens may show how the ...
