How incredibly unlikely is your birth?

A mathematician has come up with a model for assessing the probability of the evolution of intelligent extraterrestrial life...

Professor Andrew Watson postulates that 4 critical developments are required for this to occur: single-celled bacteria, complex cells, specialized cells allowing complex life forms and intelligent life with an established language. He assesses this probability as 0.01 per cent over four billion years which is pretty darn unlikely, I guess... but I'd still like to believe that someone was out there:-) And after all, you know what they say about assumptions...
