Do you really think bears were white? Here is the dilemma that science presents to us.
Nature is wise and thanks to it animals and plants have been able to adapt for thousands and thousands of years to their corresponding environments. Only those species that knew how to survive in the ecosystems are still present in them today. Each of them depends on some differential quality to be able to Get an advantage over predators and, of course, victims. In the case of polar bears, can it be said that their differential sign is their white colour?
Contrary to what he had always thought, The skin of this type of mammal is not white. In fact, it is an animal whose skin color is rather dark. So how is there such a big difference with coat color? The key is the sense of light that gives us when we see this animal. Taking into account the analysis of each hair, it can be seen that even these are not white. It is the appreciation of their servants, throughout history, to be a standard in camouflage.
Let’s see, then, what are the clues behind the color this animal has, why there is so much scientific confusion in this regard about the true color that each specimen gives, and of course how much we are facing One of the coolest sides of the polar bear. Who was to say there would be so much contrast between the inside and the outside, and besides, how could they even experience shades of green?
Why the polar bear isn’t really as white as you think
The skin of a polar bear is transparent and hollow. When light hits the outer fur, some of it is absorbed while the rest is scattered. This causes a very scattering effect, allowing us to see This animal with a whole series of different shades. In fact, it is possible to distinguish, depending on a series of variants, shades of yellow, gray, orange and even green. The light, when bouncing off the body, bifurcates, and is capable of giving multiple results.
The best example is to see What happens on a sunny day and on a cloudy day. If the sun’s rays do not hit the body, the polar bear’s coloration is likely to be more gray than usual. It is an estimate, according to information from Business interested It has been the subject of study on multiple occasions. Now, in what cases can there be a place for green tones? Algal development occurs in those specimens that were born and raised in captivity.
No icy temperatures means no icy surfaces, therefore The growth of this type of plant is common in ecosystems. Sometimes this development can occur in the tissues of polar bears, resulting in these strange shades present in the skin. Finally, what is the reason for black skin? Yes, there is also an explanation that would allow this species to be among the list of rare mythical animals on Earth. Apparently, dark colors are able to attract more heat than light colors. Have you tried to check the temperature in summer between a white car and a dark car? The differences are notable and this effect also occurs in the animal kingdom.
And so, everything seems to indicate that evolution is what allowed these species To be a benchmark in different ecosystems in which he lives. Who would have said that we would encounter a species that has evolved such a strange way of adapting to the environment?
