Earth's endemic life exists on an active planet, and its physical characteristics shape its development by affecting it in many ways. The planet's magnetic field plays its part in that scenario. In this new book, the author concentrates on this little-understood aspect of terrestrial life's existence. In an all-pervasive way, Earth's natural magnetism imparts a pulse to the life forms that exist on the planet. From the very simplest to the most complex, organisms cannot ignore their natural magnetic environment. A lot of recent research into this phenomenon has been collated and reviewed by the author. In this book, he appraises the evidence from that research in a scientific yet interesting manner.
