It is not everyday that an obscure topic like the origins of the Indo-European languages gets mentioned in the news. A topic that requires the increasing cooperation of disparate fields such as ancient DNA, genetics, linguistics and archaeology does not make news headlines in our short-attention span commercial media culture. However, it was with great enthusiasm that I read a news article about advances in the debate regarding the origin of Indo-European languages.
As a person of Armenian background, I get asked about the language and where it comes from. Armenian is a branch of the Indo-European language family. About 40 percent of the world’s population speaks an Indo-European language. That family includes English, Russian Kurdish, Sanskrit, Latin – just to name a few.
Yes, another name for Indo-European is Aryan. No, it does not mean what you think it means. Aryans are not a race, let alone a blond-haired, blue-eyed ethnicity. No, the Nazis mangled archaeology and ancient history. The term Aryan refers to the Indo-Iranian subdivision of the Indo-European family. No, it was never used to identify the entire collection of languages and peoples designated under the term Indo-European.
The French racist theorist, Arthur Gobineau (1816 – 1882) created an Aryan racial category to provide a pseudoscientific basis for his contention that human races were unequal. We all know who picked up on that invention and took it to the extreme.
Since the mid-nineteenth century, there have been numerous attempts to identify the origins of Indo-European languages. Two major scenarios have been put forward to provide an explanation. The Steppe hypothesis suggests that peoples north of the Black Sea, the Pontic-Caspian steppe lands, spread out from their homeland, and were the originators of the proto-Indo-European language. Their culture is known as the Kurgan culture.
The other compelling hypothesis is called the Anatolian. First formulated by the English archaeologist the late Colin Renfrew, the latter suggested that farmers on the Anatolian peninsula – present day Turkey – spread agricultural practices as they moved, and brought their Proto-Indo-European language with them.
Renfrew identified Neolithic Anatolia as the birthplace of the original Indo-European speakers. Hittite, an extinct language, was spoken by the farmers on the Anatolian peninsula. The Hittites, mentioned in the Old Testament, were an Indo-European people, and one of the first major civilisations in West Asia.
Which scenario is correct? That debate has simmered, and intermittently erupted with volcanic force, since the first attempts to identify the similarities between, and common origins of, words from different languages. The Dutch, and then the English, while on their colonising adventures from the 16th century onwards, noticed similarities between geographically distant languages.
For instance, English philologist and judge William Jones (1746 – 1794) noticed similarities between Latin, Greek and Sanskrit. He theorised that these languages must have had a common ancestral tongue. Earlier, Russian scientist and polymath Mikhail Lomonosov (1711 – 1765) compared different language groups – Slavic, Baltic, Finnish, Latin, Greek, Russian, German – and suggested a common ancestor for the languages of his day.
Comparative linguistics can only take you so far. The advent of ancient DNA analysis opened up a whole new avenue of investigation into the deep human past.
The Yamnaya culture, which occupied the Pontic Caspian steppe, was identical from ancient DNA as being the people who initially spread the original Indo-European language. However, the Hittites, the Anatolian branch of Indo-European speakers, did not have any Yamnaya DNA. Archaeologists know from cuneiform tablets that the Hittites spoke an Indo-European language. Was there another ancestral people that unites these disparate groups of ethnicities?
Recent DNA studies, examined by Carl Zimmer. NY Times science writer, identifies the Caucasus Lower Volga (CLV) people as the ancestors of the original Indo-European language. Being nomadic, they spread their agricultural practices and culture throughout the territories now comprising southern Russia, Ukraine, and Turkey.
The migration of the CLV people was not singular nor linear, but occurred in uneven waves. Some branches of the CLV people settled into a sedentary lifestyle, encouraged by the development of agriculture. The CLV people lived in a territory stretching from the Volga river to the Caucasus mountains about 7000 years ago.
The Black Sea and its environs forms a kind of Southern Arc of migratory channels. Branches of ancient peoples travelled to Armenia, the Balkans, Greece and Anatolia.
Before we definitively claim that the mystery of the origins of Indo-European languages is solved, let’s sound a word of caution. Perhaps I am demonstrating my inherently cautious disposition, but let’s remember one crucial fact – language dispersal and ancient DNA are not directly linked. Language is transmitted culturally and socially; DNA is obviously genetic.
If we are tracing the origins of blood groups, ancient DNA indicating migratory patterns would provide a firm tracing tool – blood types are determined by your genes. Language is socially transmitted. Human language is a distinctive feature of human culture. Animals certainly communicate, in many sophisticated ways, but they do not have words or language.
Yes of course, people who share DNA are related, and more likely to speak a shared language. Ancient DNA can resolve questions about ancient peoples and their intermixing. But language is a cultural transmission, and a person’s DNA does not nearly equate with the culture in which they are raised. It is in the intersections of life that we will find ultimate answers for our questions about language.
