A new study from the Department of Archaeology at Tel Aviv University found that the extinction of large prey, upon which human nutrition had been based, compelled prehistoric humans to develop improved weapons for hunting small prey, thereby driving evolutionary adaptations. The study reviews the evolution of hunting weapons from wooden-tipped and stone-tipped spears, all the way to the sophisticated bow and arrow of a later era, correlating it with changes in prey size and human culture and physiology.
