I'm not sure consciousness and self-awareness are the same thing. First is we can be conscious when we sleep/during REM sleep, where it's arguable we are not self-aware. And if not that, we can even do it when awake, for example when we think about a movie, or a philosophical problem, we can have conscious thoughts that are not related to the self. This leads me to believe consciousness is separate from self-awareness. Self-awareness is _one thing_, among many, that the brain can think about and be conscious of.

Sure, but capacity for self-awareness? I'd guess that hamsters dream, and that their subconscious processes (eg, desires for food and sleep and sex), and maybe even emotions, run much like ours. It's just that humans, with more complex neural networks, have more layers added on top. It's similar to how the brain-stems of everything from lizards on "up" function similarly, but humans have more-developed pre-frontal cortexes and so forth. (Don't hold me to those details, please, I'm not a neuro-anatomist! You can see where I'm going with that, though, right?)

Well in that case I'm not sure where you're going. I agree that hamsters probably have a similar consciousness to ours, which is kind of the point I was trying to make.

I think that consciousness comes before self-awareness, even though self-awareness is kind of a vague term. Self-awareness can either be an abstract knowledge that you are an organism and a discrete entity in the world (world knowledge/self knowledge), or it can be more basic and be a form of conscious experience, but as my point was, I think conscious experience is broader and does not necessarily need to be about self-awareness.

I think we agree on all of those points. I'd posit, however, that whatever "it" is, and however you define it, humans are further up the scale than other animals. That's partly why I mentioned language use; it could be the step function that allows further development. Like, sophisticated-enough communication with other conscious entities is the factor that unleashes recursive improvement. This is all highly speculative.
