In today's society we have democratic laws. But they are not applicable to big part of the world. For example, try enforcing democracy rules for, lets say, monkeys. Monkeys are able to vote, they can express their opinions, but democracy would not work here.
Same applies to other animals.
Everybody knows that humans are evolved from animals, but are they evolved far enough ?
I think we are still evolving further, and sometimes backwards. I am only sure about one thing here - there's definitely some movement.
