The lush past of the world's largest desert

The vast desert of the Arabian Peninsula was not always an arid landscape. A recent study reveals that this region was once home to a vast lake and river system. These favorable conditions fostered grasslands and savannahs, enabling human migration -- until drought returned, forcing populations to move. This research highlights the impact of climate cycles on landscapes and human societies.
