Well the basis that forms that conclusion (not trying to be smart with you or anything) is that animals do not form governments, they do not go to church, they do not build civilizations, they do not execute their own for crimes, they do not need to have material possessions; you say that you can't infer what goes on in the mind by what's reflected owtwardly, but that's simply not true. If half the scientists (not that I necessarily agree with them) are correct, we are just animals, but WE do all of these things.
Animals don't do testing on US, we do it on THEM. We dominate all of them, not the other way around (with some exceptions, see thread 'Polar bear defends itself from raving fat woman').
Quite simply, if animals had the conciousness that we have, that would also mean that they had the intelligence. If they had this intelligence, there are plenty of animals that could very easily dominate the hairless/clawless/night-visionless/soft, pink-skinned bipedal being that currently dominates the earth(Once again, see thread 'Polar bear defends itself from raving fat woman').
This is actually turning into a fun discussion

Thanks Stein, or GS, or whatever you want to be called
