A new study further strengthens ties with our chimpanzee relatives. Because it seems that, according to researchers at the University of Portsmouth, they also laugh (and smile) like us.
Like humans, chimpanzees are aware that they know certain things, they reflect on what they are thinking and act accordingly, a skill known as metaknowledge.
