Answer: It is important that cells have a "control system" because without it cells would either divide too fast or cause tumors to grow (cancer), or divide too slow and not be able to perform their cellular functions which is why the cells are controlled.
<span>Investigations of the legacy of natural selection in the human genome have proved particularly informative, pinpointing functionally important regions that have participated in our genetic adaptation to the environment. Furthermore, genetic dissection of the intensity and type of selection acting on human genes can be used to predict involvement in different forms and severities of human diseases.</span>
Everything grows we adapt and we are all made up of cells
