According to the Movie
2001: A Space Odyssey I think it happened this way.
When the ape smacked on the bone and it flew up into the air, and you hear the music of Richard Strauss's
(Also Thus Spake Zaruthustra), and the ape realized that he could use that bone to clobber the other apes over the head, BINGO, he crossed the evolutionary line and became a MAN (like Adam supposedly in the Bible).
But I think you have to give some credit to the monolith that he touched in a previous scene.
