The Near East – a swath of land that encompasses the Arabian Peninsula, the Levant, and everywhere in between – has been populated by humans longer than anywhere else in the world save Africa. It is where agriculture was born and spread into Eurasia. It is where the ancient civilizations of Mesopotamia and Egypt evolved and flourished. And it is where a particular paternal haplogroup, J1e, arose about 10,000 years ago.Paternal haplogroups define a person’s all-male ancestry (i.e. the origins of your father’s father’s father, etc.), and are passed down from father to son via the Y chromosome. Haplogroup J1e has long interested experts because it seems to have expanded and flourished in the harsh deserts of Arabia. Today it is quite common among Bedouin nomads from Saudi Arabia, United Arab Emirates, and Oman, as well as in men from Turkey, Ethiopia, and the Levant.In 2008, scientists at Stanford University proposed that the presence of J1e throughout the Near East could be tied to the nomadic hunter-herders who have dotted the region for thousands of years. In the October 14 issue of the European Journal of Human Genetics, these same scientists – including 23andMe consultants Roy King and Peter Underhill and 23andMe scientist Brenna Henn – test this theory with a little help from the field of linguistics.The authors analyzed the DNA of more than 500 men from nearly 40 locations throughout the Near East. While many of these men belonged to haplogroup J1e, there were small genetic variations within J1e based on exactly where these men lived. For example, J1e samples from Turkey were slightly different from those in Oman.When the authors examined differences among the ancient peoples of the Near East, they discovered that the languages spoken in different parts of the region were quite distinct. Until the Arabic swept across the Near East more than 1,000 years ago, there were dozens of languages spoken in the region: Aramaic in Syria, Babylonian in Iraq, and Canaanite from Lebanon to Jordan. The majority of these tongues are now extinct, but all belong to the same Semitic language family, to which Hebrew and Arabic also belong.The authors reasoned that the history of these ancient languages may be tied to that of the people who spoke them. The history of these ancient people could be deciphered further by examining their genetic ancestry via paternal haplogroup J1e.The researchers’ combined analysis of the J1e types and the ancient Semitic languages revealed some startling results. The authors found that J1e arose in Anatolia (present-day Turkey), expanding southward toward Arabia 10,000 years ago.Limited archaeological evidence supports such an expansion, when hunter-gatherer groups, using bow-and-arrow technology and with the help of domesticated dogs, headed south into the heart of the Near East. Soon after they began expanding, the hunter-gatherers took up herding, domesticating animals like cattle and goats.The linguistic evidence lends additional support. The common ancestor of all Semitic languages, called proto-Semitic, originated about 7,500 years ago, just as J1e was expanding. More importantly, the spread of proto-Semitic coincides with the spread of hunter-herders across the Near East.So what does all this mean? The expansion of haplogroup J1e is closely tied to the expansion of the Semitic languages. And they are both linked to the expansion of hunter-herders, who journeyed from Anatolia southward into Arabia thousands of years ago. We now know just a little bit more about the ancient history of this fascinating region.
