Unnatural Selection -

In modern biology, "unnatural selection" describes how human activity—rather than natural environmental pressures—forces species to evolve. Key areas include:

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. Unnatural Selection

Some experts argue we are in an "uncontrolled evolutionary experiment" where synthetic chemicals and toxins reprogram our genomes, leading to rises in autoimmune and neurodegenerative conditions. 📺 Media & Cultural Works In modern biology, "unnatural selection" describes how human

The use of CRISPR-Cas9 allows researchers to manipulate DNA by changing RNA guides to insert specific sequences. In 2018, this led to the controversial birth of the first CRISPR-edited babies in China.

The title is widely used across documentaries, fiction, and gaming:

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.
