According to a new study, the precise patterning of bird feathers relies on signaling through ectodysplasin (EDA) and its receptor EDAR -- the same signaling pathway known to be crucial for the ...

New Haven, Conn. -- Biologists testing a mathematical model of the mechanism birds use to control the growth of complex feathers found that plumed feather structures involve the coordination of at ...

Complex and vibrant bird plumage inspired Darwin’s concept of sexual selection as well as many a poem and painting. But feather patterns are not directly coded in DNA, and only now has it become clear ...

Recent research delving into the intricate world of bird feathers has uncovered a fascinating discovery: a distinct set of feather rules governing flight capabilities. This breakthrough sheds light on ...

ONLY very recently was I able to read Nickerson's paper1 on barred pattern formation in chicken feathers. Nickerson's experimental analysis by means of melanophore transplantation according to H. B.

Placement, construction, shape and material are essential nest considerations. Each species meets its own needs with its own style, developed over eons. Many bird species employ feathers in their ...

It was the absence of feathers that got conservation biologist Thor Hanson thinking about the significance of them. Hanson was in Kenya studying the feeding habits of vultures, and he noticed the ...

Feathers evolved in dinosaurs and are a key characteristic of birds today. They are arranged in a precise hexagonal pattern in a bird's skin, but it has been unclear how this happens. According to a ...
