In the fossil record, there is no evidence of anything living on land before plants. A lethal mutation is a variety of mutations in which the effect can arise in death or decrease considerably the expected longevity of an organism transmitting the mutation. Answer: These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

Mutation Causes Introduces that mutations can be caused by mutagens in the environment or can occur randomly. Certain bacteria produce oxidative species which cause DNA damage and increase the mutation efficiency. In adults, mutations in genes encoding components of the sarcomere, cytoskeleton, or desmosome are frequent genetic causes of cardiomyopathy.
