In 2003, researchers published a paper in PLoS Biology that came to a conclusion often reached by biologists studying unique, island-bound species: Borneo's pygmy elephants - forest-dwelling pachyderms of diminutive stature and timid demeanor - are genetically distinct from other Asian elephant subspecies, and they've evolved for millennia separated from their cousins in Thailand, Burma, and elsewhere. But then the researchers changed their minds.
