Adaptation in Action: Elephants Evolve to Lose Tusks Amidst Poaching Pressures

A remarkable phenomenon has been observed in elephants as a response to the relentless threat of poaching. These majestic creatures are now evolving not to grow tusks, a unique adaptation scientists have uncovered.

Mozambique’s Gorongosa National Park experienced a devastating toll on its African elephant population, with nearly 90 percent of these magnificent animals slaughtered for their valuable ivory during the country’s civil war. The ivory trade fueled the purchase of weapons, perpetuating the vicious cycle of destruction.

However, a glimmer of hope emerged among the elephants born after the war’s end in 1992. Around one-third of the females from this generation have not developed tusks, offering a glimpse into the power of evolution in response to adversity.


The shift isn’t limited to Gorongosa National Park. Other regions have also witnessed changes in tusk growth among elephants.

For instance, in South Africa’s Addo Elephant National Park, a surprising 98 percent of the 174 female elephants in the early 2000s did not grow tusks.

As poaching focused increasingly on female elephants due to their smaller tusks, a higher proportion of tuskless females emerged among the older population, according to Joyce Poole, scientific director of ElephantVoices, a nonprofit organization dedicated to elephant conservation.


The absence of tusks may change elephants’ behavior, as these appendages play vital roles in their daily activities.

Tusks are used for digging water sources and extracting bark from trees to obtain food. As a result, elephants with no tusks may need to venture further in search of sustenance.

However, researchers caution that these behavioral shifts could have far-reaching implications for the ecosystems they inhabit.


Ryan Long, a behavioral ecologist from the University of Idaho, suggests that such changes may alter the distribution of elephants across landscapes, potentially impacting the broader ecosystem.

This extraordinary adaptation is a testament to humans’ enduring impact on the animal kingdom.

The poaching crisis has driven elephants to evolve in an attempt to survive in an increasingly challenging world.
