A major event in proboscidean evolution was the collision of Afro-Arabia with Eurasia, during the Early Miocene, around 18–19 million years ago, allowing proboscideans to disperse from their African homeland across Eurasia and later, around 16–15 million years ago into North America across the Bering Land Bridge.
The earliest members of the modern genera of Elephantidae appeared during the latest Miocene–early Pliocene around 5 million years ago. The elephantid genera Elephas (which includes the living Asian elephant) and Mammuthus (mammoths) migrated out of Africa during the late Pliocene, around 3.6 to 3.2 million years ago. [16]
The African forest elephant is considerably smaller. Fully grown African forest elephant males in optimal conditions where individuals are capable of reaching full growth potential are estimated to be on average 2.09–2.31 metres (6.9–7.6 ft) tall and 1,700–2,300 kilograms (3,700–5,100 lb) in weight.

The African forest elephant (Loxodonta cyclotis) is one of the two living species of African elephant, along with the African bush elephant. It is native to humid tropical forests in West Africa and the Congo Basin. It is the smallest of the three living elephant species, reaching a shoulder height of 2.4 m (7 ft 10 in). As with other African ...
The Asian elephant is smaller than its cousin, the African elephant, and is easily distinguished by its smaller ears. ©Sourabh Bharti/iStock via Getty Images African elephants and Asian elephants ...

Asian elephants share a closer common ancestry with mammoths (genus Mammuthus) than they do with African elephants (Loxodonta). [4] The oldest species attributed to the genus Elephas is E. nawataensis from the Late Miocene-Early Pliocene of Kenya, though the validity of this species and its relationship to Elephas has been doubted.
