I'd agree with the more exotic idea. Only real requirements for the evolution of intelligence would seem to be digits that can do fine manipulation for making tools, coupled with social/language skills to pass complex ideas to the next generation. Humanoid shape is not required for either of those. Of course that's technological intelligence, complex social groups can get a species pretty far, look at some birds, dolphins, etc... Considering how long it took for a technological species to develop here, you would have to assume there's a considerable amount of chance involved. Need just the right conditions, the right group of animals pushed into the right conditions, forced to use complex tools for survival and able to do so. | |
