Evolution is change, and not always for the better. Evolution, in fact, is at the core of many of the diseases that are hardest to treat. Pathogens such as bacteria and parasites evade their host’s defenses or antimicrobial drugs through evolution. Cancer itself in an evolutionary process, whereby “rogue” cells evolve to grow beyond their normal barriers, migrate to distant locations in the body, and ultimately evade chemotherapy.
