  •  A brilliant possibility cskhendrick. I suspect (4+ / 0-)

    once they start growing different kinds of neuro-receptors such as the rattle snack ability to perceive infrared, and sharks and certain ells who are reported to perceive electro-magnetic fields, it will soon be anything goes, as far as these kinds of possibilities.

    Long, long ago, in my first year at Cornell as an electrical engineering student enrolled in a biology class, I proposed   a way that certain migratory birds might be able to detect electromagnetic waves with arrays of cells containing ions that would interact with electric fields.  It created quite a commotion and I was brought all the way up to the department head, who dismissed the idea saying the particular birds involved had no such known cells.

    I dropped out and moved to Boston, came back into Academia via a back door at MIT, and the Harvard night school, in a different field, so it turned out not to go anywhere, but I've always found these issues to be fascinating.

      and electrical sense organs. Downconverting radio frequencies may be an issue...but look at the simple crystal radio that puts out an audio frequency using a bit of natural rectifying crystal.

      Perhaps ... if there is even such an animal - a biochemical chain with piezoelectric properties.

      On the topic of migrations, insect migrations like with monarch butterflies seem to depend in part on very accurate timekeeping, perhaps tying in to location of the sun.

      After all, once Europeans had good timepieces (read: longitude) that plus shooting stars (and the sun at specific times of day) made navigation child's play.

      Maybe butterflies got a 100-million year drop on us. :)
