the theory of evolution doesnt state wether the original and bi product of evolution can live side by side. but think about it with evolution you have the original then you have the transformation and then you have the current species. Now lets think about us, if we did evolve from tarzans buddies then we started as apes..... ok, well then we started to evolve at which there was human and chimpman existing at the same time and there was blunt evidence of evolution happening everywhere, not just speculation. And then there is the current species.... the human. So there is no obvious acts of evolution going on with the humans, there are no missing links walking around sportin gucci, so that means all apes would of evolved into the human already... but there damn things are still around. And if we did evolve from a species of ape that doesnt exist anymore because they turned human... where are the artifacts? where are the fossils?

"Some conditions of evolution have come from some of a species breaking off and moving to another part of the world, then evolving to suit that location. Both species lived in the same time. Look at the different species of apes or man, thier times on this earth overlap according to science." - Dont get evolution and adaptation confused.
