The patterns of nature are everywhere without us realizing it, the similarity between some forms becomes astonishing when we decide to pay attention. Tree leaves and human eyes, for example, have the same vesica piscis shape and in both cases are associated with the reception of light. Like this example, we find many others in ways that are repeated over and over again in the places where we pay the least attention. And here also comes the case of walnuts that, if we observe them closely, we can come to the conclusion that small brains perish. Then the question arises as to why these similarities arise and apparently there are.
The cultivation of walnuts dates back to ancient times. According to historical records, since 2000 BC, signs of walnut cultivation have already appeared in ancient Babylon, a territory that currently belongs to Iraq. Since then, humans have been consuming this food, which, contrary to popular belief, is not a seed, but a fruit because it contains seeds. But among all the species of nuts, there is one that has a pattern very similar to that of our brains; the castile nut.
A very similar composition
Many have wondered why walnuts look like brains and the answer shows us the great connection we have with nature. First of all, walnuts are mostly composed of fatty acids, mainly Omega-3, which is likely to give them their characteristic shape. But it must be said that the brain also has a significant presence of fat in its composition. For this reason, it is believed that there is a great similarity, since in both cases fats make up 60% of their structure.
But this is not all, there is another factor that influences the formation of both brain tissues and the texture of the walnut and it makes so much sense that it surprised us. First it must be said that to increase the area of a flat surface within a reduced shell, the solution is simple, incorporate wrinkles to maximize the surface area. Therefore, another similarity that we find in both cases is that both the nut and the brain are safe within an oval and consistent structure that presses against the interior.
The shell and skull give shape to a tissue that has found a way to maximize its volume by incorporating wrinkles, without having to expand as much. Furthermore, in both cases this is done in a bilaterally symmetrical manner, although it is still not clear why. In summary, both species, although diametrically different, found similar solutions to the same problem. And that’s why walnuts look like brains.
