The mystery of the "fairy circles" that have appeared in Africa and Australia

The mystery of the "fairy circles" that have appeared in Africa and Australia

Until a few days ago, these admirable circumferences emerged from the earth, called fairy circles, were thought to be found only in Southwest Africa.

However, the discovery of these phenomena has just come to light far from the African continent; secret, in vast Australia. The finding makes the hypothesis that these circles are the consequence of the competition for water scarcity.

Since the 1970s, scientists have been unable to agree on the cause of the circumference pattern, having to choose between one of the two predominant divergent hypotheses: one is the one already mentioned in the introduction, the other is one that focuses on the core of responsibility for the formation of the circumferences to the small termites.

The hypothesis that frames the cause of the formation of these patterns was not developed by a biologist, but by a mathematician, a great mathematician in fact, the distinguished Alan Turing. As we can imagine, the mathematical models for this hypothesis should not be precisely intuitive. However, what we can do is get a few words out of so many numbers.

Fairy circles, what does mathematics say?

Both the pattern analyzes and the mathematical models developed in recent years show us that these circumferences are formed independently of the termites. Focusing on the African circumferences, it seems that they have the mission of watering holes, that is, they are in charge of the water store during the few times a year it rains in these places, so that it can be faced from a considerably better outlook for the harder seasons. As you can guess, the grass that grows around the drain can directly access, via roots, the water.

According to the researchers, in the roughest environments where competition for water consumption is a sure factor, the least resistant vegetation ends up dying, while the best known speciesto adapt to the environment they end up organizing in these patterns, in these circles.

As you can imagine, if such an organization in circular patterns is so beneficial for the availability of water from plants, the formation of this phenomenon on our planet would not be so rare, it would not be restricted only to Africa. That is why it is also common in Australia.

Without pretending to overshadow this more than argued theory, I propose a new one here: unless the goddess Gaea is already preparing for the Fair?
