Most of what I wished to write when this topic was first put up was already done by Kuro or others, so I don't have that much more to add.
The way humans are organized now isn't even that different from how it used to be when we were still monkeys- but of course our intelligence has grown. People have spread over the whole planet as well AND are in contact with each other over the whole earth, so yes, that organization needed a little tweaking. But still, we are beings that want the 'basic' animalistic desires: food, water, shelter and space. We still live within groups, and often express disdain towards members of other groups. Just think about racism as an example. We are still evolving because it's necessary if we want to still be able to compete with other beings. This time we are not competing with other species, though- we are competing with members of our own species.
That's a problem I see with the title of this thread. Are humans animals? Yes. They definitely are. Zero doubt about it. Should humans still be considered animals? Now that's a more interesting question, one that is able to raise debate.
