Evolution is the Process by which organisms change over successive generations through the inheritance of new traits. During sexual reproduction, a complete set of DNA is donated from each parent organism. These two complete sets of DNA then mix together to create an entirely new set, discarding the remaining, giving rise to a new organism with a completely independent set of DNA. During the process, minor changes can occur in the makeup of the DNA, called mutations. These changes are the result of randomness, or chance mistakes which just happen to occur. Sometimes these mutations cause new traits to appear in the particular organism.
