Why Zebras have Stripes
Where the Zebra got it's stripes from has been a puzzle for decades. Why would such an animal have black and white stripes, and what purpose do they serve if any?
I had to research on this topic for a class. It intrigued me at first, since I never thought that there was a reason behind it. I thought they had stripes just like how a leopard has prints.
But the more I read the more I found that it's not just for aesthetics, and that it actually has a function.
Initially I thoight it was about protection. Like camouflage from it's prey. That idea quickly got diminished because a predator can still smell the zebras and see their outline even if they are camouflaged. It wasnt a social indicator either, like denoting which species or group they belong to.
It's actually to stop flies from bitting them. Certain flies carry diseases that are harmful for zebras. Their stripes stop the flies from Landing on them so that they dont get bitten.
One study was conducted to test this theory. A few researchers visited a farm where they tool 2 groups of horses. One group was normal, brown coloured horses but the other group had a black and white striped coat on them. It was observed that the Zebra coated horses did not get bitten whereas the normal horses got bites.
This study was so interesting to me. I could only picture horses that look like zebras, in a black and white coat, standing and looking at their friends who were getting swarmed by flies.
This got me thinking. If zebras could evolve to avoid getting bites, could humans too? If there was a pattern or colour that mosquitos avoid so we cpuld prevent the spread of diseases.
A quick search tells me that mosquitos do avoid certain colours like whites, green and blues. While they do detect things like the carbon dioxide in our breath and body heat, they tend to avoid these colours.
Now I shall only be clad in blues and whites!
If there is anything that i've learnt from this research, it's that patterns in nature aren't just patterns. They provide a function to the organism, no matter how small. Whether it be in plants or animals, patterns make up a lot of the natural world around us.
We humans see the patterns in an aesthetic way, but for nature it could be the difference between life or death.
When it comes to preventing disease, should humans try to mimic nature's patterns and wear colors
Your vote is final.
This is really interesting, I also used to think zebra stripes were just like leopard prints, just natural pattern with no reason. But you are right, the more you read the more you realize it's not just aesthetics, it actually has a function. I have heard a few theories about it, like temperature control and flies. What was the most convincing reason you found in your research for class?
I love how a simple research topic turned into such a fascinating discovery! Nature never ceases to amaze us, and zebra stripes are a perfect example of how something that looks beautiful can also serve a practical purpose. Your comparison between nature’s patterns and human perception is especially thoughtful. Science makes the world even more interesting when it teaches us to look beyond appearances. 🦓💙
