Poaching is artificially selecting for tuskless elephants who can better survive, mate, and pass on their genes to the next generation. In Gorongosa National Park, Poole found that among the older female elephants, who survived a period of heavy poaching in the park, over 50% are tuskless.

Poole, who is a co-author on the new paper, combed through old natural history films and amateur videos to estimate the prevalence of tusklessness prior to the war. Using those samples, they identified candidate regions in the genome that, when mutated, seemed to explain tusklessness and its apparent male lethality.
