Scientists find eternal Nile to be more ancient than previously thought

The Nile’s unchanging path, however, has been a geologic mystery because long-lived rivers usually move over time. Researchers at The University of Texas at Austin have cracked the case by linking the river’s flow to the movement of rock in the Earth’s deep mantle. In the course of their investigation, they found the eternal river to be much older than anyone realized, with the scientists estimating the age of the Nile to be 30 million years—about six times as long as previously thought.
The research, published on Nov. 11 in the journal Nature Geoscience, found that if it weren’t for the mantle movement keeping the river on course, the Nile would have turned west long ago, probably changing the course of history along with it.
