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.

Job 🚨 Please share!!

We have a teaching track faculty opening in our undergraduate behavioral biology program @JohnsHopkins

Teaching animal behavior plus self-developed courses

@JHUArtsSciences

Work with @acgallup & me & excellent undergrads!

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

No experimental evidence for yawn contagion in galahs

[Andrew Gallup @acgallup]

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.

@Evolving_Moloch Studies comparing snake stimuli with modern threats are interesting, but have little to no relevance to the innateness of snake detection mechanisms or the overall support of SDT

@Evolving_Moloch Pulvinar neurons reveal neurobiological evidence of past selection for rapid detection of snakes

[Andrew Gallup @acgallup]

@Evolving_Moloch The evidence for Snake Detection Theory is robust. There is great work on infants, children, and non-human primates raised in captivity all suggesting innateness. You are conflating SDT, which proposes narrowly specific cognitive mechanisms for snake detection, with snake fear.

I am hiring a PhD student to study the relation between disgust and moral cognition. Master's degree required. A background in evolutionary psychology is a big plus. Please circulate!

Notes on draft

[Andrew Gallup @acgallup]

Sports, team games, and physical skill competitions appear to be a human universal and may have been prevalent throughout the hominin lineage.

🚨 Paper(s) Alert 🚨

The commentaries and reply for my BBS piece are online now.

Read my reply to find out what Mithen got wrong about Elephant-hunting; who ate the chocolates; and why we should revise our null model of Hominin Cognition!

Check out the latest issue of @IFLScience, featuring articles on why we enjoy watching fire, how connecting with plants improves our health, and why yawning is contagious

@glenngeher @AdrianaDiaz @tonydokoupil @CBSMornings Thanks Glenn!

[Andrew Gallup @acgallup]

Had a lot of fun talking with @AdrianaDiaz and @tonydokoupil about why we yawn on @CBSMornings
