It's Leveling.
The impulse to level hill and mountain, to equalize.
Also, I've noticed that a lot of animal lovers tend to be misanthropic, due to bad personal experiences with other humans.
They flee to the animal kingdom, because there they won't be judged by the creatures, like they are by other humans.
So, this nonsense about humans not being smarter than other animals could just be a subliminal resentment.
