From the New York Times….

From an analysis of the skeletons and pottery, scientists identified the two successive cultures that occupied the settlement. The Kiffians, some of whom stood up to six feet tall, both men and women, lived there during the Sahara’s wettest period, between 10,000 and 8,000 years ago. They were primarily hunter-gatherers who speared huge lake perch with harpoons.

I don’t don’t that Sahara was wet at one time. But I do doubt that a culture where people where often in the 6 foot tall primarily ate fish that they speared with harpoons.
