- Henri Kerkdijk-Otten has a lifetime of experience in understanding the mega-fauna of our prehistoric world. His interest and research today focuses on the reconstruction and rebirth of Europe's original mega-fauna such as the Aurochs, Wild Horse and Water Buffalo.
Growing up in an eastern Netherlands farming family that raised cattle, he has grown accustomed to breeding and handling of large animals. He studied History at the University of Nijmegen, with a specialization in the Middle Ages and Archaeology. He currently holds a Master degree in History and is Chairman of the Megafauna Foundation.

He was really nervous but the content of this presentation was awesome.
Fun factn in Belarusian auroch is called " Тур". The second city founded in whole Belarus in 980 a.d. that still exists today was named " Тураў " which can be translated as the " auroch's city " since they were plentiful in the area.
Thats sick. Did aurochs survive long there?
If the habitat is ready, turn out the most desirable animals and let natural selection take over.
It's an odd thing splitting human activity from nature.
@@meneither3834 Yes. But there are two different types of human interaction with animals.
There is simply hunting, and there is domestication.
What to me would be sensible would be to use historical hunting grounds and try to connect them into a bigger hunting ground. These are usually the remaining forests in Europe.
So we're not aiming to exclude ourselves here, just aiming to create space without domestication.
The wild, primeval Aurochs was an amazingly cool creature: powerful, untamed and fierce. With current DNA sequencing and geonome work, it should be possible to fully bring it back. This video is going on my "Reviving Extinct & Endangered Life" RUclips Playlist.
A very good project! It would be awesome if we could get back the aurochs!
Texas Longhorns show what happens when you leave cattle alone to go feral long enough. They were recreating Aurochs on their own. Given more time they would have even become closer to it.
Good talk. Thanks.
You'll need to bring back European big cats too to balance things out.
Basically Aurochs are just Dire Cows.
I'm a bit dubious about back breeding. It seems to me that you just end up with a new domestic cow breed.
I'd love some well-thought responses to my opinion.
+Riley B No, not really. You should pay attention to this video.
In the short term, I think you are right. The cattle will essentially be domestic cattle of a new breed or type. But the last step in the rewilding process, turning them loose to survive independently of human intervention, is the key to long-term success. Surviving on their own in nature will result in natural selection for survival traits that over a number of generations will differentiate them from domestic cattle breeds. Something very similar happened in North America when Spanish cattle escaped and became feral. By the mid 1800's, there were probably millions of feral cattle roaming what is now northern Mexico and southwestern USA. They were very wild and extremely well adapted to their environment.
Genes are just data. They descend from a native source and can be reassembled exactly given the right circumstances (largely dependent on nature). So logically it is easy to look at a few cows and run their genetics and compare to an "ancient" sample. Breed cows with the most matching DNA rinse and repeat until the whole genome becomes more and more similar to the ancient sample. Short of gene editing it is the best approach and absolutely given time can be successful.
@@r6343 True. And ultimately no population will ever have the same exact circumstances and will have to adapt to the circumstances they face.
Just like we bred wild animals to be tame, we can use the same selection process to breed tame animals to be wild.
However, I wonder if it wouldn't be faster to simply put the animals into a hunting ground, they will be hunted by us and other animals. That way they will be selected to be smarter, faster, bigger and stronger. That may be the end goal I think, but for now they're trying to breed to a point that they think these animals will stand a chance against predation.
Form to function is possible, we have the tools and can guide the rebirth of large bovines like the Aurochs. With two or more common breeds, Combine Highland with Bazadaise. Then breed for color and horn shape. Source Blue Ox Farms 1996.
+Michael McDermott That doesn´t make sense.
love how he got dressed up for his presentation
I wonder if the could bring back the cave lions, cave bears, wooly rhino, wooly mammoth, giant elk, wild horse, and Cretan dwarf hippo
A lot of this will happen on its own if you let it. But you'll need the support of the farmers i.e. paying for and installing the needed fencing that keeps predators out of lifestock fields AND it needs to be done BEFORE the predators return! Lifestock is easy food and has more bodyfat than wild prey, making it a very attractive food source. Making hunting lifestock too difficult and having enough wild prey species available enables farmers and predators to inhabit the same area without conflict. This is the part that the rewilders tend to ignore/forget/not understand.
What type of cattle did they release in Spain?
Spain fighting cattel
Sayaguesa variant
Heck cattle
Sad that he is such a bad speaker, when the topic is so interesting.
I think the major issue as to why he seems such a speaker is its not his native language and that makes it hard to pace naturally.
How good is your Dutch?
Shane Thomson yeah he just sounds really nervous poor guy I’d be even more of a mess than him if I was up there
@@pstubington his accent is horrible for a Dutch, dutch people like Scandinavians are good at speaking english.
Unfortunately these animals cannot be truly wild without large predators.
gonna need big predators to maintain those herds tigers,lions,leopards
I think these species could be nice for Rewilding:
-Subsaharian Cheetahs
-Asiatic Lion
-Siberian Tiger
-Spotted Hyena
@@DholeCC17 yea agreed
Physeter Prehistoric Express yeah don’t know how well they would do in the wilds of Europe but yeah
@@DholeCC17 What makes you think that those were all part of the Paleolithic Central European Ecological Philum?
VЄ Macrinnon I don’t think they were
Grazing Highland cattle can improve habitat ten times... more animals and more plants. a very simple tool to aid in the extension of our current mass extinction process.Why? This breed eats everything, while common breeds must eat only improved plants to maintain weight. The result bad or weed plants survive. The Highland cow is a model of sustainability and one of the most Natural bovine species. Combine Beavers, and wait, plants and animals invade and utilize every, water in the soils assures plant growth even in drought conditions, recharging the ground water.
I think this is great preserve Mather nature
What a shame it has had to come to this.
Let the 21st century be an end to greed, ignorance and stupidity.
We are supposed to be the top species aren't we?
Technically the aurochs back breeding has already happened, the nazi party breeded "hitler cows" which were almost identical in features and actions to the aurochs and 6 of the cows are happily living in England
+Guy Forrest, The British Dinosaur Man
I'm sorry but that's not true. The 'nazi cattle' which is a very stupid name by the way (the true name is Heck cattle) don't resemble the aurochs. They're too small, their horn curvature isn't good enough et cetera.
That's why they are going to breed a new aurochs like type of cattle.
As far as I know there are three different projects aiming to breed back the aurochs (Uruz Project, Tauros Project & Taurus Project.
Chris Nature I know the name is Heck Cattle, but considering what they had and how quickly they did it, they didnt do a bad job, AND NO IM NOT SUPPORTING THE NAZIS! Im just saying you got to give them credit considering what they had they wasnt all that far off when it came to outward appearances. Obviously i hate them and everything they stand for but I gotta say the Heck cattle really looks like what id picture and aurochs to look like
+Guy Forrest, The British Dinosaur Man In my opinion, Heck doesn´t substitut european primitive cattle landraces, that are adapted for centuries or millenia to local climate, type of soil, predators, diseases and so on.. It´s only suitable (and it still needs lots of changes to become close to the aurochs) for countries that don´t have primitive cattle at all. And I doubt that Heck is the best option for countries that don´t have suitable animals, with the exception of Germany and nearby countries (because it´s already found there, it can be found in semi-feral form there and consequently should be also cheaper there).
+Guy Forrest, The British Dinosaur Man If you think that Heck looks like the aurochs, then you should read this: www.amazon.com/Retracing-The-Aurochs-History-Morphology/dp/9546422355
arrrrgggghhh he is speaking to fast. combined with his accent, he is difficult to understand..
animures
Big animals died for a reason
Yes, hunted to extinction by bored aristocracy. And when the prey species where gone the wolves attacking lifestock and children (who would be out with the lifestock, they being way cheeper than fencing is now) was a good excuse to go after them too.
Eduard Gheorghiu yeah because medieval nobles slaughtered them like crazy for sport much like fox hunting
What was the reason?
