Only those mutations that are harmful will be passed-on.

Mutations do not relate to survival of the fittest.

Detailed explanation-1: -Mutations that allow organisms to survive are more likely to be passed-on. Only those mutations that are harmful will be passed-on. Mutations do not relate to survival of the fittest.
Detailed explanation-2: -A mutation occurs. If the mutation is beneficial, the animal will survive longer and reproduce more. Some of its offspring will inherit the mutation. These offspring will also have better chance of survival, meaning they live longer and reproduce more.
Detailed explanation-3: -Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
Detailed explanation-4: -(myoo-TAY-shun) Any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment. Mutations can be harmful, beneficial, or have no effect.
Detailed explanation-5: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
