The answer is cell division
Answer:
High Temperature, X-rays, Radiation, Some Chemicals
Explanation:
In general, mutations happen due to some error in the DNA duplication process, however, there are certain factors in the environment that can increase the incidence rate of these genetic errors. Excessive exposure to x-rays, substances present in smoke, ultraviolet light, excessive temperature, nitrous acid and some dyes present in food, for example, can favor the appearance of mutations. In general, we can say that mutations can be caused by high temperature, X-rays, radiation, some chemicals.
If a scientist makes the argument that she has found DNA evidence that shows that evolution does not exist, the evidence would be the weak physical similarities among closely related organism and also among distantly related.
