Sometimes, evolution is not mandatory. Take the horseshoe crab, Komodo dragon, or even a cockroach as examples. Each individual creature has remained relatively unchanged for hundreds of thousands of years, yet each species continues to successfully survive in this ever-changing world of ours. We often take for granted, or simply forget that more primitive life forms thrive to this very day as a consequence of their underlying simple forms.
So what is it about these base species that keeps them alive and well in the 21st century? Obviously, nature got it right the first time. The primal instincts and physical adaptations that Mother Nature endowed upon each species are still relevant to this day, regardless of the changing environment around them. Well, that's not exactly true; oftentimes, the evolving surroundings play both the part of the blade and the bandage, and sometimes it's the combination of the two that creates the ideal circumstance for life.
