7. Why Do We Laugh?
Now we know that crying is still a mystery to scientists, but did you know that so is laughing? Yep, researchers are baffled as to why exactly do we laugh, and what evolutionary purpose does it serve. Some argue that it goes way beyond just finding something funny, it is actually a tool to communicate with.
In fact, a study that analyzed the pattern of laughter amongst participants revealed that merely 20% of the laughs were actually caused by something funny. So they suspect that laughing evolved as a way to socially bond with each other, but the exact reason is still elusive.
