Biologists have explained a left-hand orientation of ants
Graduate of Bristol Institute of Edmund hunt (Edmund Hunt) and his colleagues are studying how the ant Temnothorax albipennis moving mazes and other locations suitable for the construction of nests. It turns out that almost always insects prefer to curve to the left.
About the reasons of this behavior, according to a paper published in the journal Biology Letters in the press release of the Institute.
Biologists have observed, as ants manifest themselves in the natural environment (in the crevices of the rocks, where they usually build nests) and intentionally designed the maze of branching paths. In all cases, insects are often turned off on the left.
Taking into account the opinion of researchers, using the left eye ants look out for predators, and the right is defined in space. Besides all this, their normal habitat is extremely similar to the maze, and continuously collapse into one and the same direction - a great strategy for inspection and search of a way out of the maze. In the end, it employs the principle of collective security: when the main mass of ants turns left, following this line of conduct ensures that an individual will not be lost.
Approximately 10 percent of the planet's population are left-handed. Specialization of the cerebral hemispheres (lateralization) is extensively distributed to other vertebrates. In recent years, scientists regularly notice the asymmetry in the operation of a motor apparatus invertebrates. This phenomenon may shed light on the origin of lateralization in animals.
