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.
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
In modern biology, "unnatural selection" describes how human activity—rather than natural environmental pressures—forces species to evolve. Key areas include: The use of CRISPR-Cas9 allows researchers to manipulate
The title is widely used across documentaries, fiction, and gaming: Unnatural Selection
