How did the zebra get its stripes? It sounds like the theme for a “Just So” story that Rudyard Kipling never got around to writing. You would think that someone would have come up with the definitive answer by now, but, in fact, the reason zebras have stripes remains a biological mystery. The laws of evolution suggest that the random emergence of stripes on the ancestors of modern zebras must have had some sort of advantage that allowed them to reproduce more prolifically than their unstriped brethren. The striped animals would have become more common with each generation, ultimately outlasting the ones without stripes.
