WebIntroduction. A central goal of modern biological research is to determine the genetic and molecular basis of adaptation and evolutionary change in organisms. Understanding the specific mutations underlying large evolutionary changes is important to address a number of fundamental questions in biology. WebA mutation is what occurs when a change alters the DNA sequence and gets passed on to future generations. Mutations are necessary for evolution to occur and to produce a new species.
