A stunning dinosaur fossil, Duonychus tsogtbaatari, found in Mongolia's Gobi Desert, shows an odd two-fingered, feathered theropod with humongous, well-preserved claws, adding new information on the enigmatic therizinosaurs.

In a nutshell Scientists temporarily reversed feather evolution in chickens by blocking a key developmental pathway, causing the embryos to grow simplified, unbranched feather structures resembling those seen in early feathered dinosaurs.

Scientists have successfully genetically modified chickens to make their feathers resemble those of dinosaurs. This study is part of a broader effort to understand how and why feathers

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 suggest that feathers evolved from simple structures known as proto-feathers.

Feathers may have started as simple filaments in ancient dinosaurs, but a team of Swiss researchers is digging deep into the genetics of feather formation by experimenting on chicken embryos. By manipulating a key signaling pathway,

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

Ancient mammals that lived in the time of dinosaurs were mostly the same dark-brown colour, according to a new study providing clues about how those mammals evolved in a time where they faced giant predators.
