Animal Planet shows animal faces. Anything with a recognizable mouth and set of eyes is still pretty engaging to our wetware.

(In fact, I just tried "Animal Planet" on Google images, and got mostly face shots -- human and otherwise.)

Good point, but I was responding to this quote: "You wouldn't watch that show unless it had a lot of humans in it, preferably attractive ones, showing their faces." Not sure why I deserved a downvote.
