Satellite images have revealed that a network of ancient rivers once coursed their way through the sand of the Arabian Desert, leading scientists to believe that the region experienced wetter periods in the past.

The images are the starting point for a major potentially ground-breaking research project led by the University of Oxford into human evolutionary heritage. The research team will look at how long-term climate change affected early humans and animals who settled or passed through and what responses determined whether they were able to survive or died out.

Until now this part of the world has been largely ignored by scholars despite its critical location as a bridge between Africa and Eurasia. In a project funded by €2.34 million from the ERC (European Research Council), a multidisciplinary team of researchers will study the effects of environmental change in the Arabian Peninsula over the last two million years. The systematic study of the Pleistocene to Holocene periods will be unique in its length and level of detail.

It wouldn't surpirse me at all...  Just like Northern Africa (to include the Sahara) was once rather lush, until whatever factors changed to bring it to where it is now (Africa closing in on Europe by tectonic drift, changing ocean and air currents, end of Ice age, etc)...

I do wonder if someplace that is 'lush' now, was at that time desert...
