Experimental evidence for yawn contagion in orangutans (*Pongo pygmaeus*)
E. V. Berlo, A. P. Díaz-loyo, et al.
This fascinating study by Evy van Berlo and colleagues explores contagious yawning in orangutans, revealing that these primates yawn in response to videos of their peers. Interestingly, they do not respond to avatars. These findings could hint at the presence of contagious yawning in the ancestors of humans and great apes, but more research is needed!
