Was rock throwing in our evolutionary path?

What makes the upright humanoid?  Stand up and throw a rock.  Hunting from a distance, defense from a distance.  Humanoid can throw rock into fruit trees, into streams.  Then they hoard rocks. Want a pile ready to take on the hunt.  But a rock hoard yields cutting rocks, different rocks; and hand eye coordination, the same rock throwing motion becomes the pounding motion. Tool age explosion.  Hand eye coordination still remains a fundamental thrill to humans, the same motion appears in all our sports.  It would be born at the thrill of blasting your first edible fruit without climbing the tree. Then take the same rock and cut it up.  What an evolutionary advantage.
