.Researchers have uncovered a novel mechanism underlying the skeletal reduction and asymmetry of emu wings. Their research reveals that the absence of distal muscle formation results in a lack of mechanostress during development, leading to the observed bone abnormalities. .Researchers have uncovered a novel mechanism underlying the skeletal reduction and asymmetry of emu wings.
