And here's an intriguing passage that tickled my "tiny green" fancy:
In my musings about animal emotions I also can't help wondering, What about the insects? Do even mosquitos have emotional lives? Of course, mosquitos have tiny brains and lack the neural apparatus necessary for the evolution of emotions, so it's doubtful they do. But in truth, we just don't know. One day, perhaps we'll figure out a way to determine this. More important, however, would it make a difference to us if they did? It should, just as it should make a difference to us that other animals have emotions. Knowing that animals feel - and being able to understand them when they express joy, grief, jealousy, and anger - allows us to connect with them and also to consider their points of view when we interact with them. Knowledge about animal passions should make a difference in how we view, represent, and treat our fellow beings.
