👉 In the context of biology, an "extinction" refers to a situation where a species' population has reached such a low level that it is no longer able to survive on its own. The extinction of an organism can be caused by various factors including changes in their environment, diseases, competition with other species, or natural disasters. Extinction often occurs because the population reaches a point where reproduction becomes impossible due to lack of resources or competition from other species. This leads to a decrease in genetic diversity
