Ivory poaching over decades has led to the evolution of tuskless elephants, researchers have found, proving that humans are “literally changing the anatomy” of wild animals. A previously rare genetic mutation causing tusklessness has become very common in some groups of African elephants after a period in which many were killed for their tusks, according to a study published in the journal Science.
Robert Pringle, of the department of ecology and evolutionary biology at Princeton University, which led the study, said it showed the impact of human interference in nature.He said: “What I think this study shows is that it’s more than just numbers. The impacts that people have, we’re literally changing the anatomy of animals.”
