Biological Time

Biological Time presents an extraordinary hypothesis about how plants and animals are timed and the knowledge of this phenomenon by prehistoric, ancient and indigenous people. The work is supported with archeological evidence and a wide range of examples from salmon, deer, and geese to grapes.

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

Highlights from the book are as follows:

- The works of art in the cave at Lascaux, France, dating back to 17,000 years ago, were solar-lunar calendars that aided Ice-Age men in knowing when and where to hunt large mammals.

- Ancient Mesopotamian calendars and religious rituals were used to time the opportune periods to harvest a wide range of plants and animals.

- The solar-lunar calendars and ceremonies of indigenous people on the Northwest Coast of North America and in the South Pacific Islands were primarily designed to gauge when fish are most easily harvested.
