Mutations are natural processes that occur when there are changes in the DNA sequence of an organism. They can arise spontaneously during DNA replication or be induced by environmental factors such as radiation or chemicals. While some may view certain mutations as unnatural due to their implications, particularly in the context of genetic engineering or artificial selection, the fundamental process of mutation is a key driver of evolution and biodiversity in nature.

An unnatural light source is any source of light that is not produced by natural occurrences like the sun or a fire. Examples include electric light bulbs, neon signs, and LED lights.
Natural radiation is primarily used for medical imaging and therapy, as in X-rays and radiation therapy for cancer treatment.
