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 ...

Patterns that guide the development of feathers and other features can be set by mechanical forces in the embryo, not just by gradients of chemicals. One of the longest-standing questions in biology ...
