New research finds that the syrinx, the vocal organ of birds, and larynx share the same developmental programming.
Humans have been long fascinated by bird song and the cacophony of other avian sounds -- from coos and honks to quacks and peeps. But little is known about how the unique vocal organ of birds -- the syrinx -- varies from species to species or its deeper evolutionary origins. A trio of recent studies is changing that. The studies include high-resolution anatomical scans of syrinxes from hummingbirds and ostriches -- the world's smallest and largest bird species -- and the discovery that the syrinx and larynx, the vocal organ of reptiles and mammals, including humans, share the same developmenta...
