Still it's kind of absurd that we are humans, and not, say, mosquitos, for the a-priori probability of finding yourself in the body of a mosquito is quite a bit higher.
If you developed as a mosquito you wouldn't have your mind, you would have the mosquito's mind - you would be the mosquito, not a human as a mosquito. You can't be and cannot have been anything other than what you are, which is a liberating thought. Alternatively, you are everything because if you had developed from the exact same initial conditions as something else you would have developed into that thing as it is exactly.
