I thought this had been discussed before somewhere in the forum, I might be wrong, though.

Anyways, a very neat discovery, it helps to explain why european bison reproduce with domestic livestock so readilly. It also is quite interesting since European bison seem to prefer a habitat that is mostly intermediate between the wet forests prefered by aurochs and the lightly forested steppes prefered by the steppe bison.

Wait was the Wisent a descendant of a hybrid of two bison species, or steppe bison and Aurochs?

It only mentions Aurochs once in the whole article, the rest of the article mostly refers to it as a "new species of bison" or just "hybrid".

Also,

"Finding that a hybridisation event led to a completely new species was a real surprise - as this isn't really meant to happen in mammals," says study leader Professor Alan Cooper, ACAD Director.


What about the Clymene dolphin? This is one of those species which later turned out to be the result of a hybridisation, the spinner dolphin and striped dolphin.

Hybrid speciation is very rare when it comes to mammals - not non-existent . Afaik there are only 2 confirmed mammal species that are descendent from hybrids : the Wisent (Bison priscus x Bos primigenius) and the Clymene dolphin (Stenella longirostris x Stenella coeruleoalba) .

Red and Eastern wolves could also be results of hybridisation between a grey wolf and a coyote , but that's yeah a controversial taxonomic status ...

Could hybrids of Polar bear and grizzly bear, be a possible contender for future Hybrid speciation, if the current affect on polar bears, caused by climate change continues or even worsens?

The difference being that "grolar bears" have not formed a distinct population and tend to represent abnormalities within their parent populations. The Clymeme dolphin and Wisent are special because they formed distinct populations and became functional species.

Eh, Eastern and Red Wolves represent the "New World Canis" group along with the Coyote, Dire Wolf, and things like Edward's Wolf, etc.


That being said, speciation through hyridization is happening as we speak within Canis in North America with the Coywolf.

Didn't know it is that rare though.

It's all very interesting, but can I just inquire as to the reasoning behind the word "abomination" in the title?

Everyone's mentioning mammals... is this kinda thing possible in other things? Reptiles, birds, and amphibians?

It's EXTREMELY common in birds and exists in other groups too.

@Fireplume : I'm only referring to some recent studies (not sure how trustworthy they are) :

''In contrast, a 2016 study of 28 sequenced canid genomes concluded that red and eastern wolves have sequences that can be explained as resulting from gray wolf-coyote hybridization.''

^it's been a theory for a while now that eastern coyotes are so much larger and aggressive than western individuals because they are actually hybrids of eastern wolves and coyotes. LAST I heard the same conclusion was arrived at with eastern wolves and red wolves.

IIRC the various species in the Carassius genus have produced fertile hybrids, same with marbled trout and brown trout (although it's still debatable whenever the marbled is a subspecies on its own or another morph of the brown). And in both cases, the hybrid populations seem to be replacing the original ones.
