The circular grass creations, that look like something out of a different planet scattered throughout the Namib Desert have long been one of the mysteries of science.
The grass seems to grow in circles and in center there's only bare desert soil. But scientist now believe they have found the cause of this phenomenon.
The "guilty-party" is suppose to be species of sand termites that eats the water-sucking grass in the circles' center and cause the water to conserve in soil and help protecting the insect from the hostile desert environment.
Norbert Juergens, a biologist at the University of Hamburg, said that the grassy circles are like an oasis in the desert, and that without the termites the desert would often be, well only a bare desert. Not all of the colleges agree completely with mr. Juergens theory, but they are all sharing the thought, that sand termites play a valuable role at preserving the moist in desert.
