Many researchers have gone into the Sahara looking for clues as to how long ago humans began inhabiting the desert. According to archeologists, the Sahara was much more densely populated thousands of years ago when the desert's climate was not as harsh as it is today. Fossils, rock art, stone artifacts, bone harpoons, shells and many other items have been found in areas which today are considered too hot and dry to inhabit. This suggests that these areas were quite habitable thousands of years ago, but that the climate of the Sahara has since changed drastically. The artifacts found were located near remains of giraffe, elephant, buffalo, antelopes, rhinoceros, and warthog, as well as the remains of fish, crocodiles, hippopotamuses and other aquatic animals which suggests that thousands of years ago water was quite abundant in the Sahara. The majority of the people living in the Sahara Desert are nomads, which means that these people continuously move from region to region in search of better living conditions. It is believed that the first nomadic peoples came to this region after domestic animals were introduced to the Sahara 7,000 years ago. Researchers believe that sheep and goats were introduced to the Sahara region by the Caspain culture of northern Africa. Over 25 percent of the Sahara's surface is covered by sand sheets and dunes. The most common types of dunes include tied dunes, blowout dunes, barchan and transverse dunes, longitudinal seirfs, and complex sand seas. Within the Sahara are several pyramidal dunes that reach over 500 feet in height while the draa, a mountainous sand ridge, reaches over 1,000 feet. Researchers have for many years tried to figure out how these dunes were formed, but the case remains unsolved.
