We know what makes us laugh, but why?

Even Aristotle was interested in the things that make us laugh. Jonathan Silvertown, Professor of Evolutionary Ecology in the Institute of Evolutionary Biology at the University of Edinburgh, joins guest host Courtney Collins to discuss the science behind why we giggle, laughter’s evolutionary advantages, and why you might want to tickle your houseplants. His book is “The Comedy of Error: Why Evolution Made Us Laugh.”
