    Domestication refers to a process where you selectively breed animals for certain traits and then over the course of a number of generations, they become genetically different enough from their original parent species that they're now considered a different species.

    The traits that were selected for aurochs when breeding them to turn them into cows were traits such as docility, size, feed efficiency, and so on. After aurochs with these traits were bred over the course of many generations, then cattle were born. The process of selectively breeding them continues to this day.

    The logic is that if they can reverse the process of domestication by selectively breeding for wild traits (i.e. aggression, size, color, horn size, etc.) then they can bring back the aurochs in its original shape and character to live in the wild alongside predators.

    Cow = domesticated aurochs
    Dog = domesticated wolf (or some extinct sister species to the wolf)
    Goat = domesticated wild goat
    Horse = domesticated tarpan
    Cat = domesticated African wild cat
    Pig = domesticated boar
    Sheep = domesticated mouflon/urial/argali
    Llama = domesticated guanaco
    Alpaca = domesticated vicuna

    And so on.

    For most of these animals that I listed, the wild form and the domesticated form exist. For the cow and horse though, their wild ancestors are extinct and that's why there are these experiments to bring them back.

    Many of these animals that were domesticated more recently return to their wild forms after being left out in the wold for a while. Britain's wild boar population consists mainly of pigs that ended up running away.

    See this: https://www.mlive.com/flintjournal/o..._revert_t.html

    Same applies to cats, they aren't even a 100% domesticated species yet.
    Why do these semi-Aurochs look different from each other? I was under the impression that the Aurochs was a single, distinct type.

    Well, there are different Auroch species that gave rise to different domesticated cattles. Western cattle came from the ancient Aurochs of Anatolia(EEF people) while the South Asian cattle came from ancient Indian Aurochs. Simple, we humans have been breeding cattle with different physical characteristics for our different uses through selective breeding. Some cows are breed for meat only, some for milk like the Frisian cows while others are bred multipurpose breeds. Zebu thrives in arid climates like in India, Arabia and even certain Latin American countries like Brazil. Zebu cattle don't yield as much milk as their European Frisian counterparts which is why they were exported from the Netherlands and Northern Germany to here which they need to have shades and cooling systems for them to say happy:


    For meat however, we eat beef from Zebu cattle from Pakistan and India.

    Different methods of breeding. They don't all "breed back" using the same breeds of cattle. Also, breeding them to turn into aurochs takes multiple generations. Many of the heck cattle (semi-aurochsen) look like they're only 2nd or 3rd generation. So it makes sense that they'd look different to the "final product".

    Most of the differences between the aurochs models seems to be horn size, horn angle/curvature, hump size, overall body size, facial features (modern cows look more neotenous), dewlap size, etc. And its hard to breed those features to perfection like how they're supposed to look on the original aurochs.

    There also seems to be a bit of disagreement on what the final look of an aurochs should be. Some include the forelocks on the aurochs' forehead, while others don't. But most of the differences in appearance between the heck cattle seem to be because they're in different stages of completion. Most of the aurochs I've seen that look complete are pretty similar. They mainly tend to get the color and horns right, but mess up in some other areas. And they look quite docile compared how they should look.

    Top is what the aurochs is supposed to look like and bottom is what many of them end up looking like:

    The projects that are trying to breed back aurochs are only focusing on Western cattle AFAIK.
