It’s called magnetoreception, and it refers to the ability to perceive magnetic fields. Several animals use it to find their way over long distances by aligning themselves with the Earth’s magnetic field. Sea turtles. honeybees, spiny lobsters, dolphins, migratory birds, and more all have a magnetic compass which allows them to use the information that’s coded into magnetic fields. We know little beyond that, however. How they use them, how they sense them, and what information they are getting from them remains up for speculation. For all we know, these magnetic fields could be used for much more than navigation for certain species.
According to Joe Kirschvink, the geophysicist at the California Institute of Technology who is currently testing humans for a magnetic sense, “it’s part of our evolutionary history. Magnetoreception may be the primal sense.” .... http://wakingtimesmedia.com
