How Life Increases Biodiversity
An Autocatalytic Hypothesis
- Available for pre-order. Item will ship after January 15, 2021
Life maximizes biodiversity; this is the hypothesis of this book. An atmosphere favorable for life, including high oxygen and the ozone layer, and favorable nitrogen and carbon dioxide levels stimulated increases in biodiversity. Symbiosis drives diversification and macroevolution; e.g. bacteria makes nitrogen available to plants. Ecosystems interact symbiotically. Horizontal gene transfer, often mediated by viruses, is common, drives major evolutionary transitions, and is “symbiotic evolution." These observations and others suggest that life has created a positive feedback loop stimulating biodiversity.

David Seaborg is an evolutionary biologist and Director of Research for the Foundation for Biological Conservation and Research, an evolutionary biology research foundation located in Walnut Creek, California. His undergraduate degree is from the University of California at Davis in zoology, and his graduate degree is from the University of California at Berkeley, also in zoology. He founded and is President of the World Rainforest Fund, a nonprofit foundation dedicated to saving the earth’s tropical rainforests and biodiversity. He also founded and headed the Seaborg Open Space Fund, named in honor of his father, to raise money and awareness to save open space from development in central Contra Costa County.
