The core of civilization hinges on the domestication of animals, above all, the cow. According to geneticists, the source of all domestic cattle boils down to one prehistoric herd of 80 head of cattle in what is now Iran. In March 2012, DNA research from scientists from the CNRS and National Museum of Natural History in France, the University of Mainz in Germany, and UCL in the UK traced the domestication of this herd back to a period 10,500 years ago (Hat tip: i09). That herd engendered the total number of cows in the world today, approximately 1.3 billion, or roughly one bovine for every seven humans on earth.

These cows were not the cows we know, but an ancestor of modern cows (Bos taurus and Bos indicus - the Zebu), called the Auroch (Bos primigenius, also known as "urus" and "wisent"). Evolving some 2 million years ago in India, they were much bigger, more aggressive and generally tougher animals than our modern cows; we would find their stature similar to that of the American Bison. There are some die hard nostalgics who believe that Aurochs still survive, tucked away in secluded Eastern European valleys (a Romanian video purportedly of modern Aurochs, also known as the Zimbru, here, admittedly shows massive animals on dainty legs, which look an awful lot like the cave paintings). The author of that video refers to yet another Millennial popular study which peculiarly brings prehistory right into the 21st century and states:
Despite these popular musings, researchers insist that Aurochs are extinct. They claim that the last Auroch, a cow, died in Poland in 1627. These animals lived especially in northern climes, but generally covered Europe, Russia, North Africa, the Near and Middle East, Central Asia, India and Asia.You’ll find a lot of things very different than what you’ve been taught. Two animals of the bovine family are claimed to be in existence in Romania; one is called BOUR and the other is ZIMBRU (alias AUROCH). The BOUR is the ancestor of cattle, not the AUROCH. The bour is a smaller animal, but has big horns and that’s where the confusion is. Etymologically, the word BOUR fits with BOS—meaning oxen in Greek and Latin. In addition, AUROCH does fit with TAURUS (meaning bull in Greek and Latin) but that word came about because bour (wild cattle) bulls were much bigger than the cow. Hence, TAUROS. The literal translation from Latin is “like a TAURO”, TAURO being the name of the Auroch. The confusion comes from the fact that Western scientists talk about only one animal, when in fact there are two.

Palaeontologists view cave paintings as contemporary Stone Age historical records of Aurochs and hence know how they appeared. The DNA sequence of the Auroch was determined in 2010. Perhaps the current boom in genetic research explains why Ice Age creatures have lately enjoyed a vogue in Millennial culture.
Given the tremendous importance of the Auroch, it is not surprising that early writing systems incorporated bovinely-inspired letters and pictograms. In northern Europe's Proto-Germanic and Old Norse languages, the rune which depicted an Auroch was Ūruz or Ur. In Old English, it was indicated by Ur or Yr. This letter became a predecessor of U or Y. The rune also means 'water' or 'rain.'
