About the Laas geel Rock art in Somaliland. I have changed the date attributed at this rock art. At first the date in wikipedia was between 10,000-9,000 and 3,000 BCE. The real date do not be so old, because the cows of Las Geel are domestics cattle ( with two-tone coats cows). In other view, archaelogical researches in the cave 7, gave radiocarbons dates between 3500 -2500 cal Bc (or BCE). These dates (charcols) are connected with a level containing rock rich in iron, used to apply red color on the walls (this rock is exogene of the site). Theses layers are rich in lithics but without ceramic; in fact, potery are very rare on the site of Laas Geel. (i added it in the article)?.
