The beginnings of this story go back to September 1991. Two tourists found the body of a person, now named Ãâtzi the Iceman, frozen at 10,000 feet on the Alps near the Austria-Italy border. A variety of medical tests showed that he died around 3300 BC. This is the oldest known natural human mummy in Europe that has provided much information on Chalcolithic (Copper and Bronze Age) Europeans.
DNA tests have shown that the Iceman has living relatives in Austria. Microevolution, as in the mutations of the mitochondrial DNA (inherited from the mother) and the Y chromosome (inherited from the father), makes it possible to trace and connect populations across time and region. When the random mutations are calibrated one has a genetic clock.
Other studies can complement the DNA evidence. Thus, even without historical evidence related to the spread of the potato plant, a scientist can deduce the Andean origin of the plant from the fact that there exist many varieties of it in Peru and just a few lines in Asia, Europe, and Africa.
Pathogens with distinct phylogeographic pattern can also be used to reconstruct recent and ancient human migrations. Researchers at the European Academy of Bolzano (EURAC) thought of doing so and they picked on the stomach bacterium ââ¬ËHelicobacter pyloriââ¬â¢, which is found in all human populations, with two major strains that are Asian and African. The modern Europeans have ââ¬ËH. pyloriââ¬â¢ that is a hybrid between Asian and African bacteria.
In research published in the 8 January, 2016 issue of the Science Magazine, the EURAC authors announced that the Icemanââ¬â¢s stomach has ââ¬ËH. pyloriââ¬â¢ that is of Indian origin (but now extinct) and not related to the hybrid variety of the modern European ââ¬Åadmixture.ââ¬Â This means that Indians as migrants were present in Europe in 3300 BC.
This is the earliest example of a pattern that has been repeated in history many a time. We have Mitanni kings with Sanskrit names who ruled in Syria for centuries in the second millennium BC. The Gundestrup cauldron found in a peat bog in Denmark and estimated to have been made about 2000 years ago has images of Indian deities on it (including, most strikingly, that of a goddess worshiped by two elephants, Gajalakshmi), and thus may have been done by craftsmen of Indian origin, perhaps in Thrace. Trade between India and the West has been traced back to the third millennium BC. Such continuing interaction must have led to diffusion of art and culture.
Now letââ¬â¢s go back to DNA evidence harnessed to reconstruct ancient migrations. An extensive genetic study of todayââ¬â¢s Europeans, which was published in June 2015 by the journal Nature, shows that they descend from three groups. First of these are the hunter-gatherers who arrived about 45,000 years ago and then came farmers from the Near East about 8,000 years ago. Finally, nomadic sheepherders from western Russia, called the Yamnaya, arrived about 4,500 years ago. The authors of the study suggest that the Yamnaya language most likely gave rise to many of the languages spoken in Europe today. Apparently, Yamnaya were speakers of a Sanskritic (Indo-European) language, and the wave that came in 8,000 years ago might also have been Indo-European.
The Iceman findings appear to corroborate this study as well as the work of Stephen Oppenheimer, who in his book The Real Eve, synthesized the available genetic evidence together with climatology and archeology with conclusions which have bearing on the debate about the post-migration population of India.
Much of Oppenheimerââ¬â¢s theory is based on mitochondrial DNA, [...]
