During Mozambique‘s fifteen years of civil war, the elephant population of Gorongosa National Park was decimated by 90%. Demand for their precious ivory skyrocketed in order to finance the conflict.

However, a rare natural trait seems to have saved a small number: tusklessness. Female elephants stopped developing them. With a surprising consequence: 51% of the surviving female elephants in Gorongosa had no more tusks after the civil war, escaping the poacher’s target.

Put simply, it prevented them from being killed. Yet, this evolutionary development could come at a high cost: Whole ecosystems across Africa could be changed if the tuskless trend continues.
