Chickens treated to inhibit the sonic hedgehog (Shh) pathway during development grow feathers that resemble ancient ...

The earliest feathered dinosaurs may have evolved their bird ... as well as melanosomes, which affect color, that may have ...

Tiny imprints in the feathers of fossilized dinosaurs have alternately been attributed to both melanosomes—pockets of melanin—and bacteria. Previous studies suggested that the imprints discovered in ...

originate from simple appendages known as proto-feathers, which were present in certain dinosaurs.By studying embryonic development of the chicken, researchers from the University of Geneva (UNIGE ...

But there is one natural wonder that just about all of us can see, simply by stepping outside: dinosaurs using their feathers to fly. Birds are so common, even in the most paved-over places on ...

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 evolved.

the dinosaur equivalent of a peacock's iridescent plumage. Vivid evidence for that theory appeared when scientists unveiled the true colors of 125-million-year-old feathers. Bird feathers and ...

Prior research has shown that patterns in melanosomes can be used to determine feather, fur, or skin coloring. This has led other research teams to learn about the coloring of many types of dinosaurs.

Researchers inhibited a gene during embryonic development in chickens to see if it would make their feathers look like those of dinosaurs. Here, we see feather buds on the 12th day of incubation.

scientists have managed to make chicken feathers more similar to the tubular proto-feathers that probably first appeared in the ancestors of dinosaurs in the early Triassic period 250 million years ...

Feathers are among the most complex cutaneous ... emerged around 200 million years ago in certain dinosaurs. Paleontologists continue to discuss the possibility of their even earlier presence ...
