Can Scientists Resurrect the Aurochs?

Return of the Aurochs | Discover Magazine

Europe’s domestic cattle are descended from the aurochs, a wild animal that died out in 1627, in a Polish forest. For some decades now, scientists have been trying to bring the aurochs back to life via back-breeding. An particularly notorious attempt was made by zoologists in the the Third Reich, resulting in sort-of/kind-of pseudo-aurochs called “Heck Cattle.”

Well, at least we know what the aurochs looked like, because our ancestors painted its picture on the walls of caves. Julius Caesar and other ancient writers described the aurochs’ size, strength, and speed. But by 1627 there were only a few of them left. The local people tried to save them, but at last a winter came that took away the last of the mighty aurochs.

We also have aurochs skeletons.

So… We have skeletons, we have pictures drawn from life, written descriptions, and many domestic breeds of cattle with aurochs DNA in them. And there are still projects ongoing to breed cattle back to the aurochs.

Can this ever succeed? Will it usher in an age of restoring colossal prehistoric animals?

And just how badly do we want that?

Cow Runs Away from Home… to Live with Bison

No, this is not a supermarket tabloid story. A domestic cow has run away from home to live with a herd of European bison in Poland’s Bialowieza Forest (https://www.modernghana.com/news/830952/domesticated-cow-runs-off-to-live-with-bison-in-the-wild.html). She seems to be having a nice time of it, so far, but they want to get her back in the barn before she’s old enough to breed.

Funny things happen in this forest. The European bison, very much like our own bison, lives there now, but it used to be the last habitat of the gigantic aurochs–the wild cattle ancestral to our own, whose pictures adorn the walls of Ice Age caves. Back in the 18th century the farmers and woodsmen tried hard to save the aurochs, but it couldn’t be done.

So nobody wants this cow to get into the bisons’ gene pool, because there are not that many of them left.

But she seems in no hurry to go home!
