Clarity of communication is not the goal here, perspective is.

When Darwin realized that we were in fact just an extension of the animals he found a new perspective that was very helpful to understand the world around us. It wasn't that evolution is true, it's just the best model we to explain biology.

That perspective is immensely useful for all sorts of applications and thats what Mensvoort is trying to do.

You are indirecting repeating the same argument the people who opposed his theories did. Making humans part of the animal kingdom hurt communication. Of course the question is whats the point of that communication?
