A question for evolustionists

[Zen Badger]

So I made a thread on morality, and a reply concerning evolution really got me thinking...If evolution got us humans where we are today, why didn't all animals keep evolving until they're humans?

For starters, humans are not the ultimate product of evolution, because evolution is not a directed process towards some ulimate end. It is merely the summed result of all of the tiny little incremental changes that allow living creatures to make the most of their environment and the available resorces.

Also, why are humans the last stop on the evolutionary train?

Why do you think they are? TOE makes no such claim.

Why haven't humans evolved into 10 armed 3 headed super-humans? I just think that with so much body-enhancing things around today, that nature would have thought of it first, instead of its product (humans). Again, no twisting of answers or preaching is gonna come from me, promise

Because nature doesn't think. Evolution is blind and cannot plan ahead. It can only deal with the present and only by overproducing babies which are winnowed out til the most suitable for a given enviroment survive to breed.
For example, a pair of breeding starlings will produce 12-16 chicks each year, if ALL of them survived to breed we would end up with a solid sphere of starlings the size of the solar system in very short order( instead of pigeons which appears to be the case).
No, most die before they get to breeding age, eaten by cats, taken by illness, whatever.
And THAT is how how evolution works, by massive overproduction of babies who's ultimate destiny is to be someones lunch.
