Fairy circles are circular patches of perennial grasses with a barren center, that emerge by millions along the southwest coast, in the deserts of Africa.

These Fairy circles have baffled scientists for decades and from the aerial images, they discovered are distributed in surprisingly regular patterns.
Study researcher Stephan Getzin, of the Helmholtz Centre for Environmental Research (UFZ) in Leipzig, Germany, said:
“The occurrence of such patterning in nature is rather unusual. There must be particularly strong regulating forces at work.
There is, up to now, not one single piece of evidence demonstrating that social insects are capable of creating homogenously distributed structures on such a large scale.”
