I've been researching a lot on the subject, and it really seems plausible to me that Kouprey is a hybrid. when we talk about hybrids we usually think that they are exactly 50% of both species, but there can be different blood degrees, and there are also hybrids that involve more than two species, which I think is the case with koupreys! from what i understand, java bantengs have 56 chromosomes, gaurs also have 56 chromosomes and zebu cattle 60 chromosomes, and these 3 species had overlapping territories, so my hypothesis is that zebu cattle (or even their wild ancestor) have crossed with the gaur and with the banteng separately, generating two different types of hybrids with the same number of chromosomes (58) and these two types of hybrids in turn, have crossed with each other generating the koupreys. observation 1: this hypothesis of mine takes into account that koupreys may have had 58 chromosomes observation 2: in relation to the koupreys fossils that predate the zebu domestication, I am not particularly convinced, I think there needs to be a more careful study of them, to really confirm their identity... but in any case this is not is a problem, as the kouprey may be a wild zebu hybrid, appearing long before they were domesticated. Note 3: The frayed horns of koupreys may have been inherited from zebu cattle! I have seen many pictures of Guzerá (Kankrej), Kangayan and Nellore bulls with worn horns. I believe that all cattle have the habit of rubbing their horns on the ground and trees, but the only ones that tend to get that peculiar shape are the koupreys and some breeds of zebu cattle observation 4: if my theory is correct it doesn't mean that koupreys are necessarily 50% zebu, 25% gauro and 25% banteng, the only rule would be the 50% zebu (which would keep the amount of chromosomes stable) the other 50% could vary to be more gauro or more banteng. For example, if a 50% gauro 50% zebu bull crosses with a 50% banteng 50% zebu cow, he will produce a 25% gauro 25% banteng 50% zebu calf, and if that calf as an adult crosses with a 50% cow banteng 50% zebu, it will produce offspring 12.5% gauro 37.5% banteng 50% zebu (it's kind of confusing, but I hope you understand) observation 5: I'm Brazilian, and here we do a lot of crosses with zebu (usually nelore), and the idea that the kouprey is 50% zebu seems quite reasonable to me, I saw an image of a kouprey calf that went to a zoo, and he looked a lot like a zebu crossbred calf, not to mention that the darker coloration characteristic of koupreys bulls also occurs in zebu, especially in the Guzera breed (kankrej) by the way, congratulations for the video, and for the description in Portuguese BR🇧🇷, I understand practically nothing of English, I even translated this text through Google translator (which explains some possible translation errors... 😅)
All that is plausible... However scientists & geologists allegedly discovered a kouprey skull from before Aurochs or Bantengs were on the scene. So if that is indeed true , it would 100% kill the Hybrid Theory. But I tend to agree with you that it's most likely a very rare case of prolonged Hybridization.
So you haven’t read ‘Resolving a zoological mystery: the kouprey is a real species’, published by the Proceedings of the Royal Society journal in 2007?
Até entendo seu ponto, tanto que no passado foi proposto isso, porém tem um estudo que já mostrou que o Kouprey de fato é uma espécie separada. ‘Resolving a zoological mystery: the kouprey is a real species’. Vale a pena dar uma olhada
@@animalpic8695 ja havia dado umas olhadas, mas o que me deixa com "um pe atrás" é que diferentes metodos de pesquisas, as vezes podem gerar diferentes resultados... como no vídeo do Pirula, onde ele explica um pouco sobre o gavial (que é uma espécie viva, e na teoria, seria mais "facil" de analizar os genes) pelo que me recordo, no vídeo ele mostra que dependendo das análises filo genéticas, o gavial muda bastante de posição... e tenho minhas dúvidas se talves isso não poderia acontecer com os koupreys, acho que teríamos que ter outras pesquisas e análises, baseadas em outros métodos, para ai sim termos certeza. Mas o que eu acho que realmente deveria ser feito, era uma mobilização nas redes sociais, juntando pessoas do mundo inteiro, com uma proposta de arrecadar dinheiro, para algumas tentativas de clonagem, ja que existe material genético relativamente "fresco"... sei que não seria nada facil, pois tudo teria que ser baseado na transparência, provando que não haveria desvios, e a equipe escolhida para colocar em prática a clonagem, deveria ser uma das mais especializadas no ramo, pois o materia genético ja tem algumas decadas, e não existem femeas de kouprey para serem receptoras do embrião clonado, portanto teria que ser feito em uma vaca zebu ou banteng (ou quem sabe ate uma vaca hibrida...)
@Kahanu Ermeyas-Tulu I've read about this study, but I'm not completely convinced. In my opinion, new studies should be carried out, with different and more modern methods! because depending on the method, it can happen that the species changes its position within the family tree (as is the case of Gavial, a species that is still alive, and changes its position a lot depending on the phylogenetic analysis) so I don't think it's right for us to base ourselves on a single study, which was carried out in 1950...
Are there any recent videos of these animals ? Wikipedia says there are around 250 left. Why haven't any been put into a Cambodian Zoo for a breeding program ?
Wikipedia didn’t say there are 250 left. It said there MIGHT BE 250 left they are still extant (still alive). Sadly, they are most likely extinct at this point.
IIRC, the last confidently recorded sighting was in 1968/9, some say 1988, but I think that's a corruption of a 1982 potential sighting mentioned in a 1983 paper. Beyond the individuals in this video, photographs of only two others can be reasonably found on the internet.
2:15 And that right there is why the Kouprey disappeared from the face of the earth. It's that simple. Poaching and unrelenting hunting ( No matter the reason why ) is why conservation laws exist and why hunters go through so much bs. Bad , Greedy and Unethical people ruin things for all people who are not.
@Alfianto Pramono, actually, the scientific names of the gaur, banteng, and kouprey are all wrong, they now belong to the genus Bibos with their scientific names now being Bibos gaurus, Bibos javanicus, and Bibos sauveli, the Kouprey (Bibos sauveli) is the most basal living member of this genus.
@@indyreno2933 gaur and gayal are as far as I know the only members of the bos genus to breed fertile male hybrids with Bos Taurus. I don’t see any reason to label them as a differen genus.

@@raihothexiv15th37 Great, more extinct shit.
@Rusty Man That is unsettling.
250 is a very optimistic number. According to IUCN, if they are still alive, the number of mature adults is certainly not higher than 50

We lost a magnificent animal
If we were nicer to them, then they could pull a plow in front of us and we could share all the good food that comes from the crops of our garden.
Shut up cringe. These were WILD ANIMALS. NOT DOMESTICS. WE ALREADY HAVE DOMESTIC YAK, CATTLE, AND BUFFALO TO PLOW FIELDS FOR US.

Is extint?
Possibly extinct, last sighting in 1988
Boss Gaurus crossbreed with Boss javanicus will resul Boss saouvaly ( perhaps)
This hypothesis is no longer valid. It was proposed in the 1950s, but genetic analysis showed that Kouprey is actually a separate species
