We would suggest that as leg stripes but not body stripes are found in non-zebra species such as E. africanus that are under heavy tabanid pressure, body stripes might stem from genetic correlation with leg stripes since more species have leg stripes than body stripes. The focus of this second type of question is the adaptive significance of features. Most people think that the zebra’s pyjama-like pelage has evolved to confuse predators such as lions and hyenas. Tim Birkhead is professor of behaviour and ecology, University of Sheffield. They can be answered in one of two ways. With their students, they observed and filmed horse flies trying to bite zebras. Why do zebras have stripes? Caro’s Zebra Stripes is one long argument also—for this is in essence a 300-page scientific paper—and as such makes a fine academic behavioral ecology monograph. Zebra Stripes His book brings together a wealth of historical and scientific information, coupled with previously unpublished data, to suggest that an answer is at hand: deterring biting flies. Caro's team found evidence that zebra stripes help to reduce biting by tabanid flies, but no reliable support for traditionally held hypotheses about the function of zebra stripes including camouflage, predator avoidance, heat management, or social interaction.

The flies didn’t seem to like the zebra coats on horses, either, but their bare heads were fair game. It's interesting to find out about why flies do or do not bite zebras..but maybe the best thing about this book is the narrative of developing the hypotheses and the experiments to test them.

The only thing they can say for certain is that the high contrast between black and white most likely tricks the fly’s low-resolution vision, which relies on sensing movement.
