Aurochs were immortalised in prehistoric cave paintings and admired for their brute strength and "elephantine" size by Julius Caesar. The huge cattle with sweeping horns which once roamed the forests of Europe have not been seen for nearly 400 years. Now Italian scientists are hoping to use genetic expertise and selective breeding of modern-day wild cattle to recreate the fearsome beasts which weighed around 2,200lb and stood 6.5 feet at the shoulder.
Breeds of large cattle which most closely resemble Bos primigenius, such as Highland cattle and the white Maremma breed from Italy, are being bred with each other in a technique known as "back-breeding".
At the same time, scientists say they have for the first time created a map of the auroch's genome, so that they know precisely what type of animal they are trying to replicate. If the Italian-led project is successful, it will raise questions of what to do with an animal which boasts a size and temper akin to a tetchy rhinoceros. It also raises questions as to what else scientists are planning to try to bring back into existence.
