Secrets of the Sahara Uncovered
determined that the human remains originated from two
distinct populations. The first group of people is known
as the Kiffians. They colonized the region when the
Sahara was at its wettest. They survived by hunting wild
animals and spearing huge perch with harpoons.
Examining the skeletons, researchers determined that the
Kiffians were of great height—sometimes standing well
over six feet—and extremely brawny.
NIAMEY, Niger Researchers with National
Geographic Magazine were hunting for dinosaur fossils in
a remote region of the Sahara. They came across a
startling find, but not of the dinosaur variety. It was of a
human kind: an ancient cemetery containing some 200
graves. Unearthed by hot desert windstorms, the
remarkable graveyard is divulging clues to two distinct
civilizations. Both inhabited the area—a thousand years
apart from each other—when the region was moist and
green.
"The Kiffian appear to have been fairly
healthy—it would be difficult to grow a body that tall and
muscular without sufficient nutrition," concluded
researcher Chris Stojanowski. Stojanowski is a
bioarchaeologist at Arizona State University. He pointed
to ridges on the thighbone of one male Kiffian skeleton.
The deep ridges reveal that he had huge, well-developed
leg muscles, Stojanowski said, "which suggests he was
eating a lot of protein and had an active, strenuous
lifestyle."
Today, northern Africa's vast Sahara—the
world's largest tropical desert—is a barren expanse of dry,
blowing sand. Long ago, however, this dry region was
lush, sultry, and overflowing with life. Seasonal
monsoons used to fall much farther north than they do
The Kiffian bones were found in tight bundles.
They looked as if they had been wrapped or slipped
inside an encasement of some sort at the time of their
burial. These bundles had since rotted away, leaving only
a tidy pile of bones.
now. In those days, a thousand years before the pyramids
of Egypt were built, the Sahara had a wet climate.
Rainfall fed a major river and formed several lakes that
supported colonies of people, acres of vegetation, and
varied animal species.
"Everywhere you turned, there were bones
belonging to animals that don't live in the desert," said
paleontologist Paul Sereno, of the University of Chicago.
Sereno, who led the team of researchers, added, "I
realized we were in the green Sahara."
The second group of people, called the
Tenerians, lived in the region 1,000 years after the
Kiffians. They were much smaller—about five and a half
feet tall. These ancient people hunted, fished, and herded
cattle. Unlike the ridges on the Kiffian skeletons, the
ridges on the bones of Tenerian males were barely
visible.
"This man's life was less [harsh], perhaps
taking smaller fish and game with more advanced hunting
technologies," Stojanowski said as he inspected the bones

"When you come across something like that in
the middle of the desert it sends a tingle down your
