The stuff in this book that was actually about the animals was wonderful and very informative. If it had ONLY been about the animals (as expected) this book would be 5 stars, but it really felt like the authors were saying Well, animals do it so obviously it's fine. They said at the very end this was not their intention, but that's how it comes across. I really was just interested in the animal behaviors and studies, not the constant comparisons to human behavior.
