This book presents a hypothesis and evidence that organisms promote and ecosystems maximize biodiversity. All species have a net positive effect on their environment, other species, and diversity. The sun is 30% hotter than when life began, but the temperature has been kept moderate by life. Life created high oxygen, the ozone layer, and fertile soil, a diverse, living system. No species evolves in isolation, and most evolution is coevolution. The nature and number of links between species are as important as species number. Eukaryotes coevolve with complex ecosystems of microbes with which they exchange genes. Genomes and intraspecific interactions both act to promote evolution and diversification. Viruses increase diversity of their hosts and cause macroevolutionary transitions.
Key Features
- Life alters the Earth in ways that increase biodiversity
- All species make their environment better for other species and promote diversity
- Life created the life-friendly atmosphere, temperature, and soil of today

Chapter
1. Introduction
Chapter
2. Life Regulates the Atmospheres Greenhouse Gas Levels and the
Earths Temperature
Chapter
3. Organisms Created High Oxygen Levels, which Allowed Complex Life
to Evolve and Diversify
Chapter
4. Species Profoundly Affect the Evolution of Other Species;
Coevolution is Fundamentally Important and Was Involved in the Vast Majority
of Major Evolutionary Transitions
Chapter
5. In Ecological Succession, Earlier Communities Create Favorable
Environmental Conditions for Succeeding, Usually More Complex and Diverse,
Communities
Chapter
6. Life Creates Soil, a Diverse Ecosystem that Benefits Life in the
Soil and Above It
Chapter
7. Eukaryotes are Complex Ecosystems with Diverse Microbiomes,
Showing the Importance of Symbiosis and Commensalism, and Challenging the
Concept of the Individual
Chapter
8. Viruses Are by Far the Most Genetically Variable and Biodiverse
Group of Organisms, Generate High Diversity in Cellular Organisms, and Are
Key Drivers of Major Adaptive Macroevolutionary Breakthroughs in Cellular
Organisms
Chapter
9. Genomes and Their Behaviors Promote Genetic Variability,
Evolution, Large Adaptive Evolutionary Innovations, and Diversification; the
Amount and Nature of Genetic Variability is Subject to Natural Selection
Chapter
10. Altruism and Cooperation within Populations Are Often Adaptive,
and Maintain Populations and Diversity
Chapter
11. Network Theory Models and Empirical Evidence Support the Thesis
that Coevolved Diversity and Connectance Correlate with Ecosystem Stability,
Productivity, Resilience, and Persistence
Chapter
12. Scientific Laws Indicate the Essential Inevitability of the
Chemical Evolution of Life Under Favorable Conditions; a Hypothesis that
Incorporates the Autocatalytic Biodiversity Hypothesis Postulates a Tendency
for Increase in Information in Systems with Favorable Conditions
Chapter
13. The Solar System, Sun, Jupiter, Earths Moon, and Nonbiological
Earth All Aid Life, Suggesting the Autocatalytic Biodiversity Hypothesis Does
Not Account for All of Earths Biodiversity, and is a Subset of a More
General Hypothesis
Chapter
14. Counter Examples to and Arguments against the Autocatalytic
Biodiversity Hypothesis and Answers to Them
Chapter
15. Implications
Glossary

David Seaborg is a renowned evolutionary biologist. He originated the concept that organisms act as feedback systems with respect to their evolution, and that they thus play an important role in guiding their evolution. This concept is a mechanism for punctuated equilibrium. He showed that the standard genetic code is on an adaptive peak, and how populations cross over maladaptive valleys from one adaptive peak to another. He published a hypothesis to explain how homosexuality evolved even though it theoretically reduces the number of offspring produced. He wrote an article on the serious non-climatic effects of excess carbon in the atmosphere. He wrote two books on his influential Autocatalytic Biodiversity Hypothesis, which proposes that all species help their ecosystem and other species, and increase biodiversity, in natural ecosystems.
He has taught biology from kindergarten to the university level.
He founded and is President of the World Rainforest Fund, a nonprofit, tax exempt foundation dedicated to saving the Earths tropical rainforests and biodiversity by empowering the indigenous people who live in rainforests.
David conceived the idea for and organized a press conference of Nobel Prize winners on global environmental issues held at the 100th Nobel Prize ceremonies in Stockholm in 2001.
