The plains zebra is the most widespread of the three zebra species, but is under pressure due to habitat fragmentation which severs migration routes. A population genetic study places the plains zebra origin in southern Africa and details the historical migration routes between populations, revealing that the subspecies classification does not match the genetic structure.
