Evolution and systematics

Antilopinae evolved from its family Bovidae, which is recognized to have a geological range of early Miocene (24 million to 5 million years ago [mya]) to Recent in Europe and Africa, middle Miocene to Recent in Asia, and Pleistocene to Recent in North America. A rapid diversification of the family into genus and species occurred possibly due to the formation of savannah habitat in Africa. The Antilopinae lineage was present by about 16-17 mya based on molecular genetic evidence. They were forced from the northern parts of Europe and Asia in the Pleistocene (which started about 1.6 mya) to their present locations in Africa and Asia, but did not cross over to North America except for the saiga antelope (Saiga tatarica), which did not survive in North America.
