It’s Getting Worsenew study out of Europe has demonstrated for the first time magnetoreception abilities in dogs. We recently discussed these amazing abilities in a range of species including fish, turtles, butterflies and homing pigeons. Even though researchers have not yet figured how these species sense and process the Earth’s magnetic field data, it is clear that these species use much more than merely the compass direction given by the field. In some cases it appears the organism is using the field intensity and inclination (the angle which the magnetic field lines make with the Earth surface) data. This new study on dogs has found yet another measurement. The dogs appear to be sensitive to real-time changes in the field’s declination angle (the difference between the field lines and true north).
So it is not so much the magnetic field, but rather the rate of change of the field, that the dogs were observed to be sensitive to. This not only implies a precise measurement ability as these declination variations are subtle, but it also implies the ability to store past measurements, so the rate of change can be evaluated somehow. This ability to compute the declination rate of change, akin to taking the derivative of a function in calculus class, is yet another monumental problem for evolution. This new magnetoreception finding reveals evolution to be even more foolish, and it’s just going to get worse.
