Two species of African elephant

This debate has been going on for a long time, but maybe this will settle it. A new paper in PLoS Biology argues the savanna and forest elephants of Africa are different species. Indeed, they diverged millions of years ago. They do still interbreed, though. And although researcher David Reich said, "We'll need to rewrite some basic biology textbooks," I don't think the more controversial pygmy elephant has ever really gotten a fair hearing despite pretty good evidence.
