In this case I happened to run smack into a pack of articles about the origins of domesticated cattle. In the map at right there is an example that the oldest domesticated strain's DNA occurs in North Africa and it does so in dominantly large numbers. It also seems that both the European type and the Indian type occur in Africa and that there are many intergrades between the two. Otherwise the cattle of the two areas are quite different and the genetic divergence between the domesticated cattle in Europe and in Inda are separated by a length of 20000 to 25000 years (that's twenty to twenty five thousand years, possibly more so counting in the Oriental breeds)

Texan (Spanish) Longhorns
There is also clear evidence that the African breeds diffused into Europe by way of Spain. And the Canary Islands also, incidentally.
This is a chart of actually distinct species of cattle. Several authorities also include bison on the list, which they classify under the same genus name Bos as opposed to Bison.
The two strains of Domesticated cattle in India and in Europe are very difference in appearance and even physiology. The Indian cattle often have prominent humps and more prominent dewlaps, and they perspire more profusely since they are better adapted for heat than the European breeds.
The European cattle have that distinctive "Rectangular" body build and they are more often shorthorned breeds, although there are also hornless and shorthorned Indian cattle.
This is a back-crossing to create a "Throwback" Aurochs bull. The early domesticated cattle of Greece, Turkey and Italy were all scarcely-modified Aurochsen. In the Aurochs species, the bull is more usually black while the cows were red or red-and-white.
Although credit is usually given for the first domesticated cattle as being in Greece or Turkey at about 6000 BC (that's 8000 years ago), it now turns out from fossil evidence that African cattle are definitely domesticated two thousand years before that (let alone the part about 20000 to 25000 years ago, which also was a separation that must've occurred in Africa)
North Africans of the Ibero-Maurusian period from 20000 to 10000 years ago were said to have been "Experimenting" with cattle and goats, but also more importantly the Barbary Shhep (Aoudads) of the Atlas mountain region which the Moullian (CroMagnon) Ibero-Marusains
were said to have been "Managing" since the idea was they could not have actually TAMED the creatures.
It also seems that these CroMagnons also "Managed" other likely types of Antelopes such as the Hartebeests. And evidently this included the tamed ibexes (Wild goats) as well, partially to go along with the notion that goats HAD to have been domesticated in the Near East, in Postglacial times.
These are Indigenous African Cattle of the type that early Saharan herdsmen would have been herding since 11000 to 12000 years ago at the very least.
And finally the skull of an Aurochs for comparison.
It seems that Atlanteans might well have had domesticated cattle, sheep and goats as part of the cultural kit Out of Africa, but in fact apart from the supposition there is no direct evidence that such a thing was so. From other evidence I feel strongly that the sacrificial cattle of Poseidon were Bison (American buffalo) which means the Atlanteans probably had domesticated dogs, and horses and elephants that were regularly captured out of half-wild, half-tamed herds; but anything else that they made use of was by way of "Experimentation." The theory needs require no more than that.
