This is a misconception that human beings evolved from apes. Human beings and other modern primates, including apes, shared a common ancestor a few million years ago. From that common point, the species diversified into a number of different directions. This speciation resulted in slightly different species (in the very beginning), which ultimately evolved into totally different species over time. Different environmental conditions, predators, etc. caused some species to evolve in a particular way, while...
