 Well, I think that's the right way to frame it. For me, what drives me is the fact that we've spent so much time with these animals. They clearly live rich and complicated lives beyond what we can kind of explain with science right now. And so it seems like one of the simplest answers is that they're able to share information via the sounds that they use in order to mediate recognizing who's who and who they spend time with, or perhaps organizing babysitting or making group movement choices.
