I was surprised to learn that during the 4000 years that elephants have been domesticated in Asia, there has been no selective breeding, and hence there are no identifiable domesticated breeds of elephant. It is still the case that companies and people that want a domesticated elephant go out and capture a young elephant and domesticate it.
I realise that female elephants don’t breed until they are at least 10, and this would slow down any selective breeding process but still … that’s 400 generations, I am surprised it has not just happened incidentally. Horses don’t normally breed til they are 3 or 4, for comparison.
The upside of this is that rewilding of elephants is easy. Captive elephants and even their offspring usually do fine when released directly into the wild.
There some 16000 captive elephants in Asia.

There are distinct separate subspecies of Asian Elephant.
I think I counted 67 different extinct species of elephant. That didn’t count extinct subspecies.
So let’s look into the subspecies of Asian Elephant. Elephas.
But first, the extinct North African elephant was domesticated. Was it the only domesticated subspecies of African elephant?
The Maltese elephant. Fossil remains of dwarf elephants have been found on the Mediterranean islands of Cyprus, Malta (at Ghar Dalam), Crete (in Chania at Vamos, Stylos and in a now under water cave on the coast), Sicily, Sardinia, the Cyclades Islands and the Dodecanese Islands. Dwarf elephants were around at the same time as people, at least as recently as 4,000 BC in one case, 11,000 BC in another. The most recent dwarf elephants are Elephas, more closely related to Asian than African elephants, but not subspecies of Asian Elephant.
The Ceylonese Elephant is a subspecies of Asian Elephant. So is the Sumatran Elephant. The Asian Elephants of Laos and Vietnam may or may not be separate subspecies.
Two extinct Elephants, the Chinese Elephant and the Syrian Elephant, are also subspecies of the Asian Elephant. The Chinese Elephant went extinct after the 14th Century BC and the Syrian Elephant went extinct about 100 BC.
OK, so far so good.
So far as I can tell, all of the subspecies of Asian Elephant were domesticated.
Doesn’t the problem of the extinction of Elephant subspecies hold more mystery than any question of changes due to selective breeding?
