Submission + - Dogs poop in line with Earth's magnetic field 4
Any anecdotal evidence, or speculation on how this would be an advantageous evolutionary adaptation?
From the article summary: "for the first time that (a) magnetic sensitivity was proved in dogs, (b) a measurable, predictable behavioral reaction upon natural MF fluctuations could be unambiguously proven in a mammal, and (c) high sensitivity to small changes in polarity, rather than in intensity, of MF was identified as biologically meaningful."
