First there was the genetic revolution—the discovery that physical structures in the cell, including DNA and RNA, shape every organism. Now, says evolutionary biologist Richard Sternberg, we are overdue for another and more profound revolution. Recent findings reveal that genetic and even epigenetic sources alone cannot account for the rich dynamism of life—not even close. Some other informational source is required.
The idea was anticipated 2,400 years ago in Plato’s Timaeus, and periodically revisited in the ensuing centuries. Sidelined by scientific materialism, it is now reasserting itself on the strength of cutting-edge molecular biology, higher mathematics, and commonsense reasoning. In Plato’s Revenge, science writer David Klinghoffer takes Sternberg’s profound explorations and weaves them into a lively and accessible account of a most remarkable realization: At every moment, we owe our lives to a genome that is more than matter, and to an informational source that is immaterial, transcomputational, and beyond space and time.

Exploring Whale Evolution: A Platonic Perspective
This chapter delves into the fascinating origin of whales, examining the process through the lens of Platonic forms and intelligent design. This approach contrasts sharply with traditional Darwinian evolution, highlighting the complexity and rapidity of whale evolution.
Introduction
The chapter begins by questioning the implications of combining Platonic forms with Darwinian evolution. It suggests that a marriage between these two concepts would require numerous intermediate forms, contrary to Plato’s original idea.
Platonic Forms and Evolution
Platonic Realm: The concept of Platonic forms implies a pre-existing template or design for each species. This perspective suggests that the transition from land mammals to whales involves a directed, purposeful process rather than random mutations.
Immaterial Genome: Sternberg’s theory of an immaterial genome involves an inference to an immaterial designing agency, competing with the materialistic and reductionistic evolutionary paradigm.
Challenges to Darwinian Evolution
Transitional Forms: The transition from Pakicetus (a land mammal) to modern whales would require thousands of genetic and morphological changes. The fossil record provides only a few transitional forms, which is insufficient to explain the complexity of this transition.
Time Frame: The time frame for these changes (around 11 million years) is considered too short for the required genetic mutations to occur through natural selection alone.
Intelligent Design Perspective
Planned Features: Proponents argue that an intelligent agency could have planned and designed the features necessary for aquatic mammals. This is supported by the concept of an immaterial genome and an extrinsic source of information guiding evolution.
Purposeful Evolution: The speed and directionality of the transition from land animal to marine animal suggest a source of purpose, a movement striving towards a vision from outside nature itself.
Specific Changes Required for Whale Evolution
Modifications: Significant modifications are needed in various aspects such as eyes, hearing, reproductive systems, body shape, musculature, vertebral column, tail fluke, breathing mechanisms, and sleep patterns.
Complexity: The number of changes is estimated to be in the thousands, far exceeding what could be achieved through random mutations in the given time frame.
Waiting-Time Problem
Genetic Mutations: Research indicates that the time required for multiple genetic mutations to coalesce and produce adaptive traits is far longer than the available time for whale evolution. For example, two mutations in hominids would require 216 million years, while whales would need 43 million years for just two changes.
Alternative Evolutionary Models
Critique: The document critiques models like neutral evolution and genetic drift, arguing they cannot account for the directionality and rapidity of whale evolution. It suggests that the information guiding evolution must come from an extrinsic source, aligning with a Platonic-Aristotelian understanding of nature.
Conclusion
The article concludes that the origin of whales poses significant challenges to neo-Darwinian theory and supports the idea of intelligent design. It emphasizes the intrinsic value and beauty of each species, reflecting a rational structure of the universe.
