I wonder if there could ever be another intelligent life form with a similar head to ours.
You see it in the movies all the time, in fact it’s rare that in a film or representation of any sort of alien creature that the alien does not have a face like our, or at least a head like ours, and when you think about it, this is really odd, because not all animals have faces like ours, or even faces at all.
Think of mollusks, like octopuses and snails, they don’t have faces. They have eyes, but on the former they are at either side of their mantle, and in the latter they stick out above their front end. The mouths for these creatures aren’t visible from the way we usually perceive them and you would probably have quite a bit of a job on your hands arguing that they have a face.
What we, and all tetrapods have (animals with four legs and their descendants) are essentially modified fish faces, and if you haven’t evolved from something like a fish, I’d love to see what sort of ancestry brought you one’s face.
I assume, I suppose, that not every inhabited planet has something like a fish, and I would probably be onto a winner there so I’m going to stick to my guns and say that in all likelihood, this is the case.
