The Borneo Elephant, also called the Borneo Pygmy Elephant, (Elephas maximus borneensis) is a subspecies of the Asian Elephant and found in north Borneo (east Sabah and extreme north Kalimantan). The origin of Borneo elephants is controversial. Two competing hypotheses argued that they are either indigenous, or were introduced, descending from elephants imported in the 16th 18th centuries. In 2003 Canadian Researcher William Sommers, through mitochondrial DNA, discovered that its ancestors separated from the mainland population during the Pleistocene, about 30,000 years ago. The subspecies currently living in Borneo possibly became isolated from other Asian elephant populations when land bridges that linked Borneo with the other Sunda Islands and the mainland disappeared after the Last Glacial Maximum, 18,000 years ago.
