>Of course the same argument applies for tentacles! And pincers... and suction cups... and single hook-claws... and most animals do their primary manipoulation with their mouths... ! There may be a few convergent constants here, independently evolved in many animals - but I suspect there may also be hosts of 'solutions' which have not evolved here on Earth at all, all equally convergent. Question is not whether something like hands exists on another world, it's whether the ETI on that other world happens to be one of them, or uses a different manipulation system. I wonder how a creature with two mouths - one for eating, one for manipulating would choose to count - in binary, or according to the number of teeth! Richard
