What might sentient extraterrestrials be like? At The Amazing Meeting (TAM) in 2011, PZ Myers gave a talk in which he expressed great skepticism about the common premise that they would be much like us.

He extrapolated from the variety of organisms that have evolved on our planet, pointing out different solutions to the same problems. Though convergent evolution can produce a lot of similarities, it nevertheless allows for a lot of differences. He compared a fish, with its mouth and some sense organs in front, to a squid, with its tentacles in front and mouth and some sense organs in the middle. Thus continuing to display his fascination with cephalopods.
