In other words, could there be any kind of other body structure that could have helped even more the intelligent brain we have. Of course taking into the Aesthetics too.
The brain is our most expensive organ, requiring massive calories and qualities protein/fat sources. In addition, it takes decade(s) to fully mature. In nature, that is a ridiculous reproduction disadvantage.<p>The only way that can evolve is through tools and social cohesion. For a small mammal to evolve to tackle on bigger game and thus more efficient protein sources, it either needs these things or adapt its body. Unfortunately, adapting your body is expensive as well. The only positive feedback loop is through tools and social behavior.<p>Wolves are intelligent animals as well. Probably as smart as toddlers. They are very social creatures that take on much bigger game. But they don't have hands.<p>From using tools, primates were able to streamline their body mass and reduce apparatus needed to digest vegetation. Thus, from the point of view of efficiency, I think the human body is very optimized for an intelligent brain.<p>It's not the only way it can happen, but it's very probable (at least to evolve from existing animals).
The human body is suited to the human brain to some degree. The human brain has human intelligence. While the discussion of intelligence in general and not just the human type is an exercise in anthropomorphism, there is no deductive basis for any claim that the human brain is intelligent in an absolute sense.<p>We can turn the ontological argument on its head. I can conceive of an omniscient and omnipotent intelligence, therefore human intelligence is very low on the absolute scale of intelligence and calling it intelligent may be misleading.<p>Going further, the question "How is a human with a different sort of body still a human?" hints at an assumption of mind-body dualism. Radical Skepticism aside, is a disembodied brain still a human?<p>I guess Aesthetics with a capital \#a were thrown into the mix to make the question less trivial?
Our hands are the most important part, it gives us alot of ability to build tools.Its highly complex and only humans posses this, its one of natures marvels. So i dont know about other parts but the the hand and the fingurs have to be the same.
