In order to establish that the traces of missile weapons, the researchers turned to modeling.  Scientists have reconstructed stone darts and spears, and then run them in the corpses of cows and sheep.  Or animal body buried in soil, or digested, followed by bone were examined under a microscope.  As a control, in addition to throwing the researchers used as a cutting and thrusting weapon – stone knives and axes.
