The throwing capacity of Middle Paleolithic points has been an important issue since the discovery of the Neanderthal’s toolbox. Homos (Neanderthals or H. sapiens) made thrusting points with limited or no throwing capability in the Middle Paleolithic. Projectile points as a long-range weapon replaced thrusting and guaranteed the survival of modern humans. Several attempts have been made to recognize the aerodynamic differences between Middle and Upper Paleolithic Points. However, up to now, far too little attention has been paid to the symmetry and projectile motion rules related to it. This paper measured symmetry and other morphological features, including length, width, weight, cross-sectional area, flatting, and elongation, on 280 points collected from five Iranian Middle Paleolithic sites. In addition, the Iranian Middle Paleolithic data is compared with several Middle, Upper, and Neolithic sites outside of Iran. The results indicate that the evolution of symmetry increased elongation and that proportionality in measurable characteristics was a critical factor in creating projectile points.
