The word evolve means “to change or grow.” explain why genetics are a evolving discipline.

The field of molecular biology provides the most detailed and convincing evidence available for biological evolution. In its unveiling of the nature of DNA and the workings of organisms at the level of enzymes and other protein molecules, it has shown that these molecules hold information about an organism's ancestry.

Like all scientific disciplines, genetics changes and grows with new information. While research shows that human DNA has changed over history, we don’t fully understand the significance of these findings. Geneticists need to conduct more research to understand the genetic history of humans.

the denominator has a very specific role.
