Sort of interesting but unnecessary
Senses for magnetic and static fields are common among all sorts of animals, and are still poorly understood.
Here's a study from Univ of Central Florida that seems to be heading AWAY from proper understanding. The authors are looking into the possibility that animals simply use the magnetic sense of symbiotic bacteria, instead of owning a built-in sense.
First, there's no real need for this extra ENTITY.
We already know that some magnetic senses use internally-created magnetic particles in a mechanism similar to the otoliths in the balance sense or the electroliths in radio fish. There's no reason to presume that the other versions would outsource the job to bacteria.
Second, an obvious counterexample:
If the sense comes from bacteria, animals kept and raised in "clean" captivity for a long time should lose their magnetic sense. Pigeons have been bred and raised in captivity for thousands of years. Some varieties have been purely domestic, with known and registered pedigrees, for hundreds of years. They haven't lost their ability to navigate. This also applies to dogs and cows, though their navigation ability isn't as purely magnetic as pigeons.
This study sounds more like a reason to use AI and Big Data because the people doing the study enjoy AI and Big Data.
Our symbiotic relation with computers helps to destroy our natural sense of reason and logic. The more we outsource our intelligence, the less we use our own.
Natural law. We were given an infinite variety of internal abilities and resources. God expects us to USE THEM FOR GOOD, not to let them atrophy.
