How Chickens Grew Dinosaur Feathers (Then Changed Back)

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, they’ve recreated structures resembling proto-feathers, revealing just how resilient and evolutionarily refined the feather-development process has become. Even when […] Read More
