In modern biology, "unnatural selection" describes how human activity—rather than natural environmental pressures—forces species to evolve. Key areas include: 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 Human-induced evolution caused by 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. 📺 Media & Cultural Works Pollution and habitat

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.
