Why Europe Is Quietly Bringing Back an Animal That Went Extinct in 1627
The last aurochs, an ancestor of modern cattle, vanished in Poland in 1627. However, a groundbreaking scientific effort is bringing these magnificent creatures back. Through selective breeding, a new breed called the tauros is being reintroduced t...

Giants of the Ancient World
Aurochs, also known scientifically by the scientific name of Bos primigenius are not your typical cattle. They were enormous, strong and powerful creatures, with huge horns, sweeping wings and an unbeatable speed. Ancient stories paint a vivid depiction of their strength. Julius Caesar once described them as being nearly the size of elephants and possessing amazing power. They didn't spare the animals or humans as they were determined to attack them.
They were the first basis for the contemporary cattle. Research suggests that the current worldwide cattle population is derived from a mere 80 female aurochs domesticated within the Near East around 10,500 years in the past, just after the Agricultural Revolution. Through the course of time, selective breeding changed this wild beast into a better-managed livestock that we see now.

The Long Road to Extinction
Aurochs first appeared in fossil records about 700,000 years ago. They then began developing into different lineages over continents. Over thousands of years, they flourished. But, in the Middle Ages, their numbers started to decrease sharply.
The loss of habitat and hunting activities were major factors, since the increasing human population have pushed into their territories. A further factor could be a disease caused by domestic cattle. With the decline of their herds the last remaining herd of cattle in Central Europe came under the guardianship of Polish royals.
At first, efforts to protect the environment were fairly robust. In the beginning, the Polish Crown controlled the forests and supervised the wildlife. Over time, however changes in the political climate affected these protections. The reigns of Zygmunt I and Zygmunt August, the dedication to the preservation of the species diminished. At the time of 1604, just the aurochs had a few.
A royal decree was released calling for immediate measures in order to save the aurochs, but it was too late. As per a report in 1630 the aurochs that died, which was female, been killed three years before through natural cause. In her absence an animal species that lived for a number of years was wiped out from Earth.
A Legacy Hidden in Plain Sight
Although they died out, aurochs never really went extinct. The aurochs' genetic heritage lives in the modern cattle industry, providing researchers with a unique chance that rare species extinct provide. In contrast to animals like the woolly mammoth and the dodo Aurochs left an active genetic footprint.
The realization of this has led to an expanding field of study that focuses in "de-extinction" through selective breeding. An example of this is presented in a paper entitled "Back-Breeding the Aurochs: Genomic Reconstruction of an Extinct Species," done by researchers from the University of California, Davis in the United States. This study examines the ways that ancient genetic material and the latest breeding methods are able to create species that closely resemble ancient aurochs, both in the appearance as well as their ecological roles.
The Rise of the Tauros
Based on the findings of this study Conservationists and scientists have developed a specific breed that is known as the tauros. The tauros aren't identical to the aurochs but are breeds derived from the oldest cattle lines with many characteristics of the original breed, including large bodies, strong constructions, and distinctive the horns.
A few hundred tauros are already being introduced to Rewilding programs throughout Europe which includes regions like Scotland and the Netherlands as well as in the Iberian Peninsula. The purpose of these animals goes far beyond creating a new species. The animals are utilized to help restore ecosystems that are natural, for grazing areas to promote diversity and balance in the ecosystem.
A Comeback Within Reach
The notion of bringing species that have gone extinct back to existence often seems like a piece of science fiction. But, in the instance of the aurochs it is now a real possibility. A combination of DNA that is preserved and modern genetic tools and the selective breeding process has created one of the most feasible strategies to fight extinction.
The thing that makes the story of aurochs so compelling is the relatability. They were not remote fictional creature. They were a part of the human history and were involved in interacting with ancient civilizations as well as influencing the development of agriculture. The disappearance of these people was gradual and driven by humans, but now their return could be influenced by the hands of humans.
Looking Forward
The loss of last Aurochs 1627 signaled the end of a time, however this may not be the last chapter. While science is pushing boundaries, the boundary between revival and extinction gets more and more unclear.
If the tauros or similar initiatives continue to be successful and continue to be successful, the next generation will see herds of similar aurochs wild animals roaming the open countryside. These animals are not merely relics of the past but instead as active players in the restoration of nature.
So, the solitary loss that occurred in an Polish forest that was lost centuries ago could turn into one of the most amazing comebacks recorded in the history of nature.
