Humans did evolve from "chimp", to be exact, ape. The first stage of the human evolution into ape was called the Australopithecus. It was around for about, roughly 6 million years ago to 3 million years ago. After the Australopithecus came the Homo Habilis, Homo Erectus, Gro Magnon, Neanderthal, whom all developed more human like traits that categorized themselves. The "Half Monkey" was the Homo Erectus. But no one is calling it the half monkey, it was the third stage of the five stages, all stages where equally important.
