The animal kingdom is full of exotic, strange, and remarkable creatures that aren’t so different from ourselves. They love, they laugh, they get angry, they get scared, but most of all they provide us with all the things that make us human. Although many species have been around for much longer than modern humans, we have a bit of an evolutionary advantage. Here are some of our favorite facts about today’s species that prove we’re all a lot more similar than we thought.
