Hunting and fishing often remove individuals with "desirable" traits (like large size or tusks), leading to populations with smaller bodies or tuskless offspring, as seen in Zambian elephants. Unnatural Selection

Pollution and habitat fragmentation force rapid adaptation. For example, North American songbirds have modified wing shapes to survive deforested areas, and sea snakes in polluted waters have developed darker skin to shed toxins more efficiently.
