Electro-sensitivity, a 6th sense lost during evolution

You are probably wondering what makes the Mississippi paddlefish or polydon and the axolotl (amphibian), a salamander from Mexico interesting to us? What do they have in common and what deserves our attention?

In fact, they share with many other animals a particular neurosensory faculty, that of detecting the electric (electromagnetic) fields released by all living beings with their "Lorenzini bulbs" placed in the protruding part of the head. These sensory organs allow them to perceive the electric fields and currents emitted by an object or by a living body in motion, such as those of a prey or a predator moving in the water within the earth's magnetic field. A real asset for hunting but also for defense and protection.

Scientists wondered whether this common ability of some aquatic and terrestrial vertebrates was the result of an identical adaptation to certain environmental conditions or whether it was a characteristic inherited from a common ancestor?

To answer this question two researchers, Willy Bemis, professor of ecology and evolutionary biology at Cornell University (USA) and Melinda Modrell, a neurobiologist at the University of Cambridge (UK), joined forces and compiled and reviewed the results of 25 years of studies on these two species.

The first species represents the lineage of origin of some 30,000 terrestrial vertebrates, the second represents the lineage of the so-called "ray-finned" fishes, which are also the origin of some 30,000 species. These two lineages are thus descended from a common lineage that split several hundred million years ago.

The results of their work, published in October 2011, show that the electroreceptors of all species develop on the same model and from the same embryonic tissue of the skin. This confirms that it is indeed a common ancestral system of perception.

One of the two species mentioned above is the common ancestor of all vertebrates, reptiles, birds and mammals (including man), but it seems that in the course of their evolutionary history, they have lost this ability to detect weak electric fields, as well as the sense organs related to it.

What if certain faculties that are commonly called the 6th sense, electrosensitivity, aura vision, etc. were simply a vestige of this supposedly disappeared sensory faculty?

What if this electrosensitivity, currently qualified as pathological and which causes so many problems in our universe oversaturated with electromagnetic pollution, was simply natural and that it was our insensitive fellow creatures who were "out of the ordinary"?
