What is a Mutation and why do they exist?
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light or Predator change. When the sequence changes the organism mutates and the mutation is either beneficial or detrimental. Mutations can either cause cancer and kill an organism or it can help the species that mutates raise their chance of survival. Usually, mutations happen for a reason or a birth defect. Mutations leads to evolution and that has lead to humanity. Mutations are the changes needed for evolution.
