A Serbian boy manifests magnetism strong enough to hold onto metal objects, http://www.dailymail.co.uk/news/article-1360081/Bogdan-The-seven-year-old-Serbian-boy-appears-magnetic.html
Animals of course migrate by way of earth's magnetic field and recently it's been discovered that humans carry a gene in their eye http://www.bionews.org.uk/page_97703.asp
that makes a protein, cryptochrome, which in insects senses the earth's magnetic field.
Consider that it would be logical that these capacities didn't stop evolving at that point, but continued to evolve into the behavioral modules of consciousness, or, looking at it another way, energy provided the template on which mental states and cognition evolved, which would then explain why human beings intuitively describe emotional experience in terms of energy; "wired," "chemistry between them," "animal magnetism," "drawn together as if by gravity," "electricity was in the air," etc., etc., etc..
