Genetics and the spread of agriculture – Domestication of animals

Posted by Fredsvenn on November 9, 2014

Genetic studies show that Neolithic farming defused from Armenian population into Europe. Haplogroup G for example has it’s highest diversity within Armenians, which indicates that it originated with Armenians and spread to Caucasus and Europe.

Haplogroup G, together with J2 clades, has been associated with the spread of agriculture, especially in the European context. The homeland of this haplogroup has been estimated to be somewhere nearby eastern Anatolia, Armenia or western Iran, the only areas characterized by the co-presence of deep basal branches as well as the occurrence of high sub-haplogroup diversity.

Haplogroup diversity spanned from a low of 0.21 in Adyghes, to highs of 0.88 in Azeris (Iran) and 0.89 in eastern Anatolia and 0.90 in Armenia. We estimate that the geographic origin of hg G plausibly locates somewhere nearby eastern Anatolia, Armenia or western Iran.

Concerning the presence of hg G in the Caucasus, one of its distinguishing features is lower haplogroup diversity in numerous populations compared with Anatolia and Armenia, implying that hg G is intrusive in the Caucasus rather than autochthonous.

The invention of agriculture was a pivotal event in human history. The first animal tamed by people was the dog. Its domestication probably occurred in the Early Stone Age, in the period of hunting development. Centuries later, people managed to tame sheep, pigs, goats, and cows. The Armenian Highlands are crucial in this regard. The oldest center of stock farming can be traced to the Armenian plateau.

The population of the Armenian plateau was among the first to domesticate animals. One of the most significant reforms in the history of mankind made comprehensive changes in the economic life of the society and exerted immediate influence on the formation of new mythology and systems of chronology.

In a paper: “Domestication and early agriculture in the Mediterranean Basin: Origins, diffusion, and impact” Dr. Melinda A. Zeder (2008) argues that the early spread of agriculture known as the Neolithic revolution spread from the Armenian plateau through a mix of colonization and cultural diffusion, into Europe and elsewhere.

On the slopes of volcanic massifs of Armenia, 3000 meters above sea level, one can find whole galleries of rock drawings of agricultural motives. Some of these petroglyphs are dated as far as the 12th -11th millennium BC.

Baverley Davis (2007) in his chronology describes: “Petroglyphs found in Armenia (one of the possible sites for the Indo-European homeland) show the oldest pictures of men driving chariots, wagons, and plows, with horses doing the pulling.”

The first farmers depicted the great history of agronomics in petroglyphic drawings. The symmetric arrangement of predominantly zoomorphic heroes was an indispensable attribute of the new times. The harnessed bulls, for instance, represented not only the process of tillage, but also the mystery of fertilization. This explains the presence of the most important element in the drawing, which is the central cruciform axis bearing a certain religious meaning.

Grapes were first grown for wine approximately 8,000 years ago, in the Armenian Highland, and by 3000 BC had spread to the Fertile Crescent, the Jordan Valley and Egypt. Near the village of Areni (in Southern Armenia), in the same cave where the oldest leather shoe was found, archaeologists (in 2011) have also unearthed a 6,100 year old wine production press for stomping grapes, fermentation and storage vessels, drinking cups, and withered grape vines, skins, and seeds.

Ancient-wine expert Patrick E. McGovern, a biomolecular archaeologist at the University of Pennsylvania Museum in Philadelphia, called the discovery “important and unique, because it indicates large-scale wine production, which would imply, that the grape had already been domesticated.”

The discovery is important because wine-making is seen as a significant social and technological innovation among prehistoric societies. Vine growing, for instance, heralded the emergence of new, sophisticated forms of agriculture. As domesticated vines yield much more fruit than wild varieties, larger facilities would have been needed to process the grapes.

Archaeologist Gregory Areshian of the University of California, Los Angeles (UCLA) said: “They had to learn and understand the cycles of growth of the plant. They had to understand how much water was needed, how to prevent fungi from damaging the harvest, and how to deal with flies that live on the grapes.” “The site gives us a new insight into the earliest phase of horticulture—how they grew the first orchards and vineyards”, he added.

The discovery that wine-making using domesticated grapevines emerged in Armenia corroborates with previous DNA studies of cultivated grape varieties, McGovern said. Those studies had pointed to the mountains of Armenia, and neighboring countries as the birthplace of viticulture. From a social perspective, alcoholic beverages change the way we interact with each other in society, often facilitating supernatural believes and religious practices.

Agriculture allowed for the support of an increased population, leading to larger societies and eventually the development of cities. It also created the need for greater organization of political power (and the creation of social stratification), as decisions had to be made regarding labor and harvest allocation and access rights to water and land.

Agriculture bred immobility, as populations settled down for long periods of time, which led to the accumulation of material goods and creation of a common culture, that was able to spread with advances of technology.
