• A new study provides a clearer timeline for one of the most significant prehistoric sites worldwide for the study of human evolution. • By integrating three advanced dating techniques, researchers have determined that the site of ‘Ubeidiya in the Jordan Valley likely dates back to at least 1.9 million years ago. • This revised age suggests that ‘Ubeidiya is among the oldest known sites of early humans outside of Africa.

  • A recent study has revised the age of the ‘Ubeidiya site in the Jordan Valley, pushing it back to at least 1.9 million years ago. Researchers combined three advanced dating techniques-likely including optically stimulated luminescence, electron spin resonance, and thermoluminescence-to achieve the new estimate. The older date places ‘Ubeidiya among the earliest known human occupation sites outside Africa, offering fresh insights into early hominin dispersal. The finding underscores the importance of precise chronometric methods in reconstructing the timeline of human evolution.
