I'm only going to refer to this last reply since we're going way off topic

proto-European humans survived an ice age before we even knew how to tame horses or use anything better than stone for tools, right?
Homo Habilis, a homo sapiens predecessor, was already capable of creating stone tools, manipulating fire, and probably other technological advancements. And it is estimated they disappeared around 1.4 million years ago. Way before any hominids ever set foot in Europe. Homo Ergaster/Erectus eventually reached Europe and led to Homo Sapiens Neanderthalensis, but by then they already had elaborate clothing. Not to mention Homo Ergaster already had many cognitive mechanisms for language. Homo Sapiens Neanderthalensis, who adapted successfully to an ice age, had a larger brain than we do and were extremely capable. They had tool workshops which imply, of course, shared mental models of the world and of others. It is no small feat to simply "survive an ice age".

Nah, I have to disagree with that. I think that as individuals homo sapiens will score as the most intelligent species no matter what definition you use.
If any professor of cognitive science, neuroscience, artificial intelligence, or anything in between heard you say that, they would have you committed. That is, to begin with, a logical fallacy. There is necessarily at least one definition of intelligence in which humans are not the best. For example, if you define intelligence as the mental capacity to compute and generate visual representations of heat waves. Or listen to anything above 22 KHz.
Frank Wilson in his book "The Hand" (1998) refers to intelligence as (paraphrasing) the ability to discover, weigh and relate facts, in order to solve problems. A good definition of intelligence *has* to be applicable to other species as well, not just humans. This has been the labour of many scientists for almost a couple of decades.

Again, I don’t think that’s true. There are pretty clear difference between the minds of humans and animals. For instance, animals are generally vastly inferior to humans in the social cognition department. You observed that animals don’t seem to give each other names. Whether that’s true or not I don’t know but it would fit what else we can say for certain.
For one thing, animals seem incapable of grasping that their fellow animals have minds.
You're playing with fire there. Have you read about any primatology experiments within the last 10 years? Chimpanzees, for example, not only have models of other's minds but they know how to effectively use their proto-theory of mind. There is a documented case in which a female chimpanzee is reclining against a rock, facing her male which happened to be a high ranking chimp. Behind the rock, was her lover. And she was caressing her lover with her own hands, right in front of her male, with the knowledge that he could not see that she was cheating on him because, from his perspective, he couldn't see her lover, being covered by a rock. Likewise, it has been found chimpanzees have a food gathering radius in which all findings must be shared. It happened that this one chimp was barely out of the circle when he/she found some food (let's say bananas). So he did what every ape does when pondering: he scratched his head, and finally decided that would not share his food and ate it all by himself. He knew he was out of the circle and they would not see him.
Primates are on an entirely different category. Maybe your average fish never questions what other fish do. But especially apes are way, way more intelligent than you give them credit for. In fact, chimpanzees have faster cognitive development than humans in the early years. Bluntly said, a 4 year old chimp is smarter than a 4 year old human, even using OUR own rules and tests.
Chimpanzees also have a remarkable ability to learn by imitation. They however cannot teach other chimps how to do things. If they did, maybe they would develop even more impressive skills.

Eh, not really. We can counterbalance these “deficiencies” with the fruits of our intelligence. We didn’t come to be the global apex predator from the 3rd degree trophic level for no reason.
The fruits of our intelligence being technology? If so, yes, we create technology to help ourselves adapt to the environment, since we don't have claws or fangs or wings. But we only "dominated" the Earth in this ridiculously small time frame because we found ourselves without major predators outside of Africa. Had we stayed there, no technology would have saved us from extinction.
Look at this from a historical perspective. Homo Sapiens Sapiens is no more than 200,000 years old. The Earth is approximately 4,500 Million years old. That is about 0.004% of the Earth's age. We are insignificant. There were others before us and others will come after us. We are animals with the ability to step beyond our animal nature and treat others with respect, love and compassion. But the truth is most of the time we choose not to use that which separates us from *other* animals. So what is the point of artificial tests of intelligence if we simply take things because we feel entitled to them?
And as a tie-in, it makes me angry that people think life on Earth exists for us to take advantage of it, without realizing we are but an insignificant sigh for nature.
