Pako - quite serious. Though I'm not familiar with the case for parrots, it's certainly true that dolphins, pigs and chimpanzees are self-aware. They are amongst very few species that, when confronted with their own reflection, will identify that reflection as their own and not another member of their species.
If you fancy a laugh, put a cat in a room with a mirror on the wall at cat-height.
Oddly enough, I have a cat that does not react to his own reflection like its another cat. It would seem he is aware that it is himself. Of course, he is an unusually smart cat, but still...
And don't forget orangutans and elephants.
I never knew pigs were self-aware. Smart as a whip, but not self-aware.
Elephants? That's one huge mirror.
Depends how far away it is. I can see all of myself in a mirror that's shorter than me, if it's at the right height and distance.
The simple answer is that humans are not further evolved than every other species at all. Our brains are bigger and better developed (hence we are more intelligent) than other species, but that's really where our advantage ends. On another level, we are no more evolved than prokaryotic bacteria. The basic processes of life - respiration, metabolism, protein synthesis, energy storage/use etc. - are largely unchanged across all species from the point when they became effective (in the prokaryotic world), so from a biochemical point of view, humans are not any further evolved than anything else, even prokaryotic bacteria. On a biomolecular level, a bacterium such as E. coli contains and produces biomolecular machinery as complex as anything seen in a human being. On a chromosomal level, there seems to be no correlation whatsoever between chromosome number or genome size and intelligence (rats have about the same number of genes as humans, cows have more chromosomes than we do, the human genome is nowhere near the largest etc.). Anatomically too, there are plenty of examples in the natural world of organs/sensory apparatus that do a better job than their human counterparts - e.g. the eyesight of an Eagle. So why are we the dominant species? Doubtless it is because 'intelligence' is a trump card in the evolutionary arms-race, and because our brains have adapted in such a way that we have become 'super-intelligent', we have become the dominant species on the planet (killing off our closest competitors/relatives in the process). But remember that even this trump card that we hold is not a human innovation, but an adaptation - loads of creatures (past and present) possess brains, and many have developed intelligence independently too. Therefore, to claim that we are so much 'further evolved' on the strength of a single advantageous adaptation would be (in my view anyway) inaccurate... it would, however, be fair to say that we are so 'dominant' as a result of our intelligence, but we shouldn't confuse domination with evolution.Why are humans so further evolved than every other living creature on the planet when we all evolved from the same single celled organism?
Absolutely serious. There is a network of African Greys who regularly communicate with each other via a simplified email system much like we do here. One, in particular (coincidentally named Alex) has quite a large vocabulary. He can tell his handlers what he wants for dinner, and whether or not he's thirsty.Are you guys being serious?

It does beg the rather obvious question: is self-awareness or even intelligence a hallmark of (evolutionary) success? There are innumerable species that are arguably as successful at living on this planet as we are, without the need for self-awareness or intelligence (as we define it) at all. Time will tell whether it's a long-term advantage or not. In the space of 1/3000th of the time dinosaurs lived on this planet, we've come from obscurity to developing nuclear weapons capable of destroying every human being on Earth, thanks to our 'intelligence'...
Regarding evolutionary success, one word: cockroach.
The most likely to outlive, outlast and outsmart all other current beings on our planet, including mankind. Could probably survive nuclear fallout.

Depends on what you consider success. I'd say our complete and utter domination of the planet should be considered hugely successful compared to other long lasting animals. And I seriously doubt that mankind will kill itself off. We've managed not only to have nuclear weapons capable of destroying every human being on Earth, we've also managed to be smart enough NOT to kill every human being no the planet.

WikipediaCro-Magnons lived from about 40,000 to 10,000 years ago in the Upper Paleolithic period of the Pleistocene epoch. Cro-Magnon were anatomically modern, only differing from their modern day descendants in Europe by their more robust physiology and slightly larger cranial capacity.[3] They had a diet of meat, grain, wild carrots, beets, onion, turnip and other foods. All together they had a very balanced diet.
Surviving Cro-Magnon artifacts include huts, cave paintings, carvings and antler-tipped spears. The remains of tools suggest that they knew how to make woven clothing. They had huts, constructed of rocks, clay, bones, branches, and animal hide/fur. These early humans used manganese and iron oxides to paint pictures and may have created the first calendar around 15,000 years ago[4].
The Cro-Magnons must have come into contact with the Neanderthals, and are often credited with causing the latter's extinction, although morphologically modern humans seem to have coexisted with Neanderthals for some 60,000 years in the Levant[5] and for more than 10,000 years in France[6].
From the movie, Matrix: as spoken by Agent Smith -
"I'd like to share a revelation I've had during my time here. It came to me when I
tried to classify your species. I realized that you're not actually
mammals. Every mammal on this planet instinctively develops a natural
equilibrium with their surrounding environment, but you humans do not. You
move to an area, and you multiply, and you multiply, until every natural
resource is consumed. The only way you can survive is to spread to another
area. There is another organism on this planet that follows the same pattern.
Do you know what it is? A virus. Human beings are a disease, a cancer of
this planet. You are a plague, and we are the cure."
I find this disturbing if only because it does ring true. However, we have not always lived like this - consuming our planet in such excess - we used to live "within" its capacity about 1,000 years ago. But we may never again want to be so disciplined and cooperative with nature once we have tasted the fruit of excess.
