4. Homo Sapiens as the species to which all modern human beings belong and is the only one from genus Homo that is not extinct.

Not all primates developed into apes. Even apes belongs to primates, they are very differ from all of the other primates. It took million years, strong natural selection, certain environmental factors to evolve few species of primates into apes, and even less species of apes were evolved into Hominids.
A major physical characteristic that separates apes from Homo considered to be the volume of the brain. Volume of the brain in about 500 cm3 matches to the volume of the brain of child when they start to speak.
