TEN PULSES OF EVOLUTION:The Logarithmic Nature of Evolutionary Time — Second Expanded EditionWhat if evolution doesn't move at a steady pace—but unfolds in pulses that arrive faster over time?In Ten Pulses of Evolution, the four-billion-year history of life is viewed through a simple, consistent lens: a series of accelerating thresholds where major forms of life appear in clustered bursts. The pattern emerges by following "e;halving nodes,"e; moving from 4 billion years ago to 2 billion, 1 billion, 500 million… and so on. This means major evolutionary change keeps occurring in roughly half the time. From the origin of life to the first hominins, each pulse marks a leap in sensation and processing, mobility, and social connectivity.This expanded edition shows that these turning points are not isolated events. Around each one, entire ecosystems expand—flowering plants, birds, and other life forms rising in parallel, forming broader waves 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 broad change amid a myriad of details becomes clearly visible. As this pattern becomes more understandable, we not only gain a greater awareness of the interconnectivity between all living forms, but a sense of our own deep origins.
