The more we learn about animals (see the article on HN ~2 days ago that bees engage in play) the more it seems like they're a lot more like us than we'd like to think. We're smart, and we can try to explain every thing away (like you do in your comment), but there's a pattern that's emerging. It's an uncomfortable pattern and I get why we try to convince ourselves that animals are fundamentally different than we are, but I'm more and more believing that we're all actually a lot more similar than we'd like to think.
A lot of my current thinking is from the book How to be Animal by Melanie Challenger. I recommend it!
