That's a pretty bold statement considering what kind of fucked up shit is going on in the animal kingdom. Animals raping each other, or eating their children, for example. There are numerous examples of nature making animals do things that we humans would consider inherently immoral.

Just because we humans are social animals and are very dependent on each other and therefore don't hurt each other, doesn't mean everyone is. Immoral acts are only immoral from our perspective. From the perspective of evolution, it's not about not getting hurt, it's about insuring the survival of the species. By any means.

And I would argue the same for beauty.
