Given that smiling/laughing is a primal instinct that we do not do on purpose (babies laugh when they are happy) to express happiness and joy, are there any other species that do the same?
In: Biology
Wolves smile and laugh as well as joking. I lived and worked with a six generation pack of wolves for over thirty years. They have quite a bit of language, a sensor humor, count, do basic math and are gossips.
