The loss of tusks is a result of natural selection. Elephants with smaller tusks or no tusks at all are less likely to be targeted by poachers, as the ivory obtained from them is less valuable. Over time, this selective pressure has led to an increase in the proportion of elephants with smaller tusks or tusklessness in these populations.
Tusks are important for elephants as they serve various purposes, such as digging for food, stripping bark from trees, and defending themselves against predators. However, the loss of tusks does not seem to have a significant negative impact on the overall survival of elephants. Tus tuskless individuals have adapted to their environment and can still thrive in their natural habitats.
The evolving loss of tusks in elephants is a direct consequence of human activities, particularly the illegal ivory trade. Conservation efforts aimed at combating poaching and protecting elephant populations are crucial to ensure the long-term survival of these majestic creatures in their natural ecosystems.
