Some aboriginal people never developed the concept of left and right, instead using cardinal directions. I've heard that a few can even tell such directions in total darkness, but am having a hard time finding a source for that. I suspect that humans once had similar EM sensitivity to birds in the same way we once had senses of smell that rivaled dogs, and that these traits may randomly resurface in a handful of people.

First: we don't have it anymore, and it's extremely unlikely that a pretty advanced extra sense just pops up in random people. Second: the Earth's magnetic field is quite static, while radio waves (the supposed contamination source) with some strength ranges from 100kHz to 5GHz. Third: the Earth's magnetic field has always been here, and there always has been EM background noise, so any recent effects must be attributed to intensity.
