Plants and animals time themselves by rhythms of light and darkness.  We often think of the sun and how it transforms the seasons, but illumination from the moon governs the night and presents equally important influences.  Prehistoric people understood these relationships and used their movements to mark time and plan for important events, such as when to hunt, fish and gather wild fruits and roots.  Farmers utilized this same formula to forecast the success of crops and animals.  Great civilizations were built and religions formed based on this methodology, which is still practiced by some indigenous peoples. Biological Time presents an extraordinary hypothesis, supported with archaeological evidence and a wide range of examples ranging from salmon, deer, and geese to grapes 

Biological Time is for the naturalist, scientist, outdoors person, gardener and all those who wonder what clocks Nature follows.
