What causes mutations?

Question

If a group of humans lived underground in a cave for an extended period of time (and producing offspring), would a situation like this cause mutations?

Can you give me other examples of mutation in evolution of animals and plants.

Thank-you!

A situation like this would not cause mutations, because the factors which cause mutations, are two:
- Certain chemical substances (such as caffeine, formaldehyde, aromatic hydrocarbons).
- Radiation (such as X rays, Gamma rays, sun's UltraViolet light).

However, mutations don't always cause disease. As a matter of fact, most mutations happen automatically and are actually beneficial for evolution.
