Research Methods
Toward this goal, this research project implements the comprehensive investigation of pre- and proto-historic nomadic cultures in the Arabian Peninsula, focusing on the five millennia spanning from the early Neolithic when sheep and goats were first domesticated to the Early Bronze Age when full-scale nomadic society based on tribalism is supposed to have been established (Fig. 1). The target research fields include the al-Jafr Basin (southern Jordan), the Hijaz Highlands (NW Saudi Arabia), the Majma/Thumamah Plain (central Saudi Arabia), Bahrain Island, and the eastern desert of Egypt.
