11/22/2023 0 Comments Are zebras white black stripes blackSome scientists theorized zebra stripes heat and cool the air near the animal in a way that creates mini air currents. Hypothesis 5: Temperature regulation Black absorbs heat and white reflects it. However, other equids like horses can recognize individual horses without the stripes, so no evidence has suggested that individual recognition of zebras has to do with their unique striping. Charles Darwin thought the stripes help zebras choose a mate for reproduction. Some researchers suggest perhaps zebras can identify each other by their stripes. Hypothesis 4: Identification Life is about more than just not getting eaten! Every zebra’s pattern is unique. Lions are also statistically more likely to seek out and hunt zebras than other prey, so nothing about stripes seems to deter lions from targeting them. Similar to a skunk’s black and white coat, famous British naturalist Alfred Wallace proposed that the stripes say, “mess with me, and you’ll regret it.” When researchers simulated the eyesight of lions, they found they could only see stripes at close distances when the predators would already be committed to a hunt. They may dazzle you with their cute and cuddly looks but they kick, bite and kill. Hypothesis 3: Warning Do not mess with a zebra. Many animals use camouflage, however zebras travel in groups and defend themselves, two characteristics not associated with camouflaging animals. Another long-believed hypothesis is that zebras can camouflage and hide from predators amongst the trees because of their stripes. Hypothesis 2: Camouflage What else looks like stripes in a savannah? Tree branches and tall grass look somewhat similar. Can you see how that could be a bit bewildering? While confusing a predator is the most commonly repeated theory about why zebras have stripes, there’s a catch: lions do most of their hunting at night when the striping effect is less noticeable. Hard to focus, right? Now imagine you are a lion and your hand is fifty zebras running away from you. Hypothesis 1: Predator confusion Spread your fingers out in front of your face and move your hand left and right quickly. Here are just a few of the explanations scientists have proposed about those dazzling zebra stripes over the years, and how they are holding up to research. So just because there are flaws discovered with a hypothesis, it doesn’t mean the effort wasn’t hugely beneficial in advancing our scientific understanding. Our understanding of how the natural world works changes as we continue to ask questions, design good experiments and collect data. They are true until proven otherwise, a fundamental aspect of scientific exploration. These educated guesses are tentative, a building block from which to base other research and allow for others to test. Many scientists have proposed ideas on why zebras have stripes.
