American scientists finally figured out the secret of the mysterious crop circles! Who is not only attributed creating perfectly smooth circles. Some said that they made people (but how then to explain the absence of traces?), someone attributed to these circles of divine origin, and most were inclined to think that the circles draw the alien ships. But last week shrouded mystery was solved! There were more than ordinary explanation of unusual shapes. Strange circles draw... Hedgehogs! Yes, these little spiky creatures, as it turned out, curled in a ball and roll around on the field in a circle!

Now zoologists studied this strange phenomenon. They have two versions of the behaviour of these mammals. Scientists have divided into two camps. First argue that the strange movements of hedgehogs and overrunning of crop circles is just an ancient instinct, which they retained from the time of the dinosaurs. The fact that allosaur attacked a colony of sand dollars and was trampled them. That though somehow to protect yourself, hedgehogs began to ride in a circle, putting the plant into a perfect circles. Thus, small animals fall into a trance high dinosaurs and remained intact.

Another group of zoologists have found a more simple explanation: the overrunning of crop circles is a trap for mice, birds and rats! Scientists managed to find out that long before hibernation Jerzy begin to roll out the circles to mice and small birds build its nest in a tightly interwoven stems of plants. When the victim appears brood, Jerzy attack the nest and eat their prey. Thus, hedgehogs provide a necessary for wintering stock of trace elements and minerals.

Already this year, cameramen and photographers of the National Geographic channel will start to shoot a film about the hedgehogs and finally razvenchayut myth about the origin of the mysterious crop circles.
