...Why did'nt it evolve alot more?.....

Darwinian evolutionary success depends on natural selection of beneficial change. If there have been changes that were not really beneficial, the species will stay as it has been.

Also, A seperate species can evolve in a different location as a result of changes there but the original can still exist elsewhere.

You mean like the fact the most evolved species is the weakest on the planet?? What happened to survival of the fittest. Should we not resemble the other creatures on the top of the food chain, such as big teeth, big claws,immense size, fur to keep us warm (or cold blood for that matter. What happened to survival of the fittest, a kitten could last longer than a human when exposed to the elements.
