New Research Traces Origins of Human Laughter

Variation in laughter tempo across five great ape species (orangutans, gorillas, bonobos, chimpanzees, and humans): each dot represents an individual observation; color indicates phylogenetic distance (in million years ago); each square contains an image of the corresponding species, with a matching dot color for intuitive reference.
