If we did evolve from apes, why haven't ALL apes evolved to human beings?

We can't do that , we already are apes. Advanced apes to be sure. What would be our evolutionary advantage to losing the ability to speak , losing the use of our thumbs and growing back a rogain promised mass of hair?

None , some can go that way ( Creationists) but not all . We evolve in all directions at once and going back to a primal ape does not look viable , unless we nuke ourselves back to that point.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
