About this episode
Many animals, humans included, are natural-born criers. It’s the most basic form of communication from right when we come into the world. But us humans are unique: we keep on crying until the day we die. What was born as a survival mechanism, develops a deeper fundamental need as we grow older. In this episode, we discover the hard-wiring in our brains that reach across species, and how our tears into adulthood make us distinctively human. Featuring Dr. Susan Lingle, Behavioral Ecologist at the University of Winnipeg, and Dr. Ad Vingerhoets, Research Psychologist at the University of Tilburg.
