The history of Somaliland, a country in the eastern Horn of Africa bordered by the Gulf of Aden, and the East African land mass, begins with human habitation tens of thousands of years ago. It includes the civilizations of Punt, the Ottomans, and colonial influences from Europe and the Middle East. Prehistory Somaliland has been inhabited since at least the Paleolithic. During the Stone Age, the Doian and Hargeisan cultures flourished. The oldest evidence of burial customs in the Horn of Africa comes from cemeteries in Somalia dating back to the 4th millennium BC. The stone implements from the Jalelo site in the north were also characterized in 1909 as important artefacts demonstrating the archaeological universality during the Paleolithic between the East and the West. According to linguists, the first Afro-Asiatic-speaking populations arrived in the region during the ensuing Neolithic period from the family's proposed urheimat ("original homeland") in the Nile Valley, or the Near East. Other scholars propose that the Afro-Asiatic family developed in situ in the Horn, with its speakers subsequently dispersing from there. The Laas Geel complex on the outskirts of Hargeisa in northwestern Somaliland dates back around 5,000 years, and has rock art depicting both wild animals and decorated cows. Other cave paintings are found in the northern Dhambalin region, which feature one of the earliest known depictions of a hunter on horseback. The rock art is in the distinctive Ethiopian-Arabian style, dated to 1000 to 3000 BCE. Additionally, between the towns of Las Khorey and El Ayo in eastern Somaliland lies Karinhegane, the site of numerous cave paintings of real and mythical animals. Each painting has an inscription below it, which collectively have been estimated to be around 2,500 years old. Antiquity Land of Punt Most scholars locate the ancient Land of Punt in the Horn of Africa between present-day Opone in Somaliland, Somalia, Djibouti, and Eritrea. This is based in part on the fact that the products of Punt, as depicted on the Queen Hatshepsut murals at Deir el-Bahri, were abundantly found in the region but were less common or sometimes absent in the Arabian peninsula. These products included gold and aromatic resins such as myrrh, and ebony; the wild animals depicted in Punt include giraffes, baboons, hippopotami, and leopards. Says Richard Pankhurst : "[Punt] has been identified with territory on both the Arabian and the Horn of Africa coasts. Consideration of the articles
