TEN PULSES OF EVOLUTION:
The Logarithmic Nature of Evolutionary Time ? Second Expanded Edition

What if evolution doesn't move at a steady pace?but unfolds in measured pulses that arrive faster over time?

In Ten Pulses of Evolution, the four-billion-year history of life is viewed through a consistent lens: a series of accelerating thresholds where major forms of life appear in clustered bursts. The pattern emerges by following "halving nodes," moving from 4 billion years ago to 2 billion, 1 billion, 500 million... and so on. This use of a scaling factor of two means that each major evolutionary threshold arrives in roughly half the time of the preceding one. These nodes not only mark times of origin, but also reveal that the evidence unfolds logarithmically around them, with precursor and explicit events appearing in predictable ways. From the origin of life to the first hominins, each pulse marks a leap in sensation and processing, mobility, and social connectivity.

This updated and expanded edition also shows that these turning points are not isolated events. Around many of these nodes, entire ecosystems expand?flowering plants, birds, and other life forms rising in parallel, forming a broader wave of change. Together, vertical breakthroughs and horizontal expansions reveal a structured rhythm in evolution?one that can be traced in the fossil record and explored as a testable framework.

You are invited to take an evolutionary journey, one in which significant change amid a myriad of details becomes clearly visible. As this pattern becomes more understandable, we gain a greater awareness of the interconnectedness between all living forms and a sense of our own deep origins.
