Excited to share our new paper in @CommsBio on the evolution of yawning in vertebrates! In the largest study on yawning ever conducted (species N > 100), phylogenetic analyses provide further evidence that yawning is an adaptation for cooling the brain. rdcu.be/cj4U9

Across two experiments, we tested for yawn contagion in galahs by presenting videos of conspecifics yawning. We found no difference in response following exposure to yawn footage or non-yawn control footage.

These results contrast with studies on budgerigars, suggesting contagious yawning has evolved independently in restrictive avian lineages.

Does yawning mean our brains aren’t getting enough oxygen?

Yawning is a complex reflex that may be triggered by changes in state of being, but its purpose is still unknown.

Reminds me of a remarkable fossil that was on display in Guyot Hall at Princeton while I was a postdoc. A great example of a behavior that was fossilized
