Abstract:

Lightning activity on Earth generates extremely low frequency (ELF) radio waves that are global in nature and called the Schumann Resonances.  This electromagentic "noise" has existed in the atmosphere for billions of years.    In addition, most electrical activity in vertebrates and invertebrates occurs in the ELF range, with characteristic spectral maxima below 50 Hz. The origin of these frequencies in organisms is unknown and remains a mystery.  In some animals, the electrical spectrum is difficult to differentiate from the natural background atmospheric electric field produced by lightning.  We propose that over billions of years during the evolutionary history of living organisms on Earth, the natural electromagnetic resonant frequencies in the atmosphere provided the background electric fields for the development of cellular electrical activity. We present evidence for the link between the natural ELF fields and those found in many living organisms, including humans.
