While I've heard that asserted, I am not certain it is true. When they were pups, each of my (two) dogs would "play" with his own reflection, indicating that each thought it was another dog. Now, as adults, my dogs are mostly indoor, big city apartment dwellers, they do not get to interact with other dogs as often as they'd like and they will in fact bark and howl at other dogs they see out the window or on TV (because they want to play with them). But they no longer react to their own reflections. They can clearly see their reflections, but they recognize that the reflection is not "some other dog". They certainly are not introspective about what it means to see their own reflection, and not vain in the way that humans can be when we see our reflection. As for Penrose and quantum mechanical structures in the brain, he asserted it as an hypothesis, but it's never been demonstrated that he is correct (and there are some who maintain outright that his particular theory of microtubules is wrong, and I'm sure you're aware in the case of people like Max Tegmark). Penrose/Hameroff's conjecture is interesting, but until there is evidence for it, the most one can say is that the conjecture is as of yet unproven and some calculations suggest it is wrong.
