Role of life's timekeeper—a novel theory of animal evolution

This article presents a new theory of animal (metazoan) evolution, suggesting that it was partly mediated through a biochemical oscillator (cycler), named Life’s Timekeeper, present in all animal cells. The cycler controls cell maintenance and repair, thereby determining how long cells survive (longevity). It originated in the single-celled ancestor of all animals, which had very short cell longevity. Animal evolution progressed by extending cell longevity, and this was mediated by extended cycle time of the oscillator. Multi-celled animals and cell-cell communication systems evolved later. The cycler controls the overall rate of development and aging, these time periods being proportionate to
