In the 1960s, the archeologist Gabriel Camps investigated the remains of a hunting and fishing community dating from about 6700 BCE in southern Algeria. These pottery-making people (the "wavy line" motif again) were black African rather than Mediterranean in origin and (according to Camps) evidenced definite signs of deliberate cultivation of grain crops as opposed to simply the gathering of wild grains. Later studies at the site have shown the culture to be hunter-gatherers and not agriculturalists, as all the grains were morphologically wild, and the society was not sedentary.
