Summary Introduction
To review:
The necessity of mutation for the evolutionary processes.
Introduction:
The mutation can be defined as the changes in the sequence of the genome of an organism. These are permanent alterations, which lead to the change in the sequence of genomic DNA (deoxyribonucleic acid). It can be caused by the radiations or chemicals. The mutation is basically alteration in the

Why are regulatory genes important to the evolutionary process? What is a mutation as defined in this course and readings. Are the end results of a mutation always "good" or always "bad"? Or is a mutation perhaps neither always good or always bad and could be "neutral or no effect" or "adaptive" in some situations? Does it depend on the gene, amino acid, protein, and case-by-case scenario? What genetic evidence suggests that humans are a part of a biological continuum with all life forms.
