Summary: Mutations are a change in DNA. DNA is what gives the living thing its looks and characteristics. Mutations can be beneficial ,harmful or neutral towards the animal or living thing. They are quite random which makes it pretty difficult to handle or notice. Somatic mutations are types of mutations that affect the living thing but it will not pass on to offspring. Mutations that make the organism die are called - Lethals. Not all mutations matter to evolution, Somatic mutations don’t help with evolution because the mutation the living thing has will not be passed down to the offspring. The only mutations that will matter and possibly help towards evolution will be those mutations that have the ability to be passed down to offspring which could impact the next generation and possibly cause evolution.
SP1: Asking questions and defining problems
We asked questions like "Do mutations have anything to do with evolution." and our answer to that was yes and no. That is because not ALL mutations are inheritable to their offspring. ONLY somatic mutations can be passed on to the offspring of the affected organism which could lead to evolution in the long run.
