I think you need to have a better understanding of how evolution works.  It&#x27;s not the Victorian model where the human is more evolved much less more perfect than any other animal.  In fact animals that reproduce faster have more opportunity for evolutionary impact -- the cockroach is far &quot;more evolved&quot; than a human.  Consider it a big parallel hill-climbing problem with each animal being a local optimum <i>for its environment</i>.<p>A human, including its brain, is the best general-purpose device for transmitting genes, but the human brain lacks structures that would be useful to an elephant, and vice versa.  Brains are not general-purpose devices.<p>Consider my dog: the surface area of his nose is probably about the size of a football field and I would bet his olfactory cortex is about the size of his visual cortex (in some breeds, it&#x27;s probably even larger).  Of course our visual system is more dominant than our olfactory system.  So that&#x27;s a simple example...would you really call one of them &quot;inferior&quot; to the other?<p>[Edit: fixed the amusing typo &quot;hill-sliming&quot; -- we are not snails!]
