Two out of the three domains of life were shown to be microbial, and the amount of microbial diversity was much larger than for macroscopic groups like plants and animals. The New Foundations of Evolution takes us into a world that classical evolutionists could never have imagined: a deep phylogeny based on three domains of life and multiple kingdoms, and created by mechanisms very unlike those considered by Darwin and his followers. This is where Jan Sapp's book The New Foundations of Evolution: On the Tree of Life fits in, as it contains a look at the history of microbial evolutionary biology. Lamarckian Leaps in the Microbial World, In Snait Gissis and Eva Jablonka eds.

That Sapp makes his story so sparkling is an achivement all the more impressive when one remembers he must include a fair amount of taconomy, both antiquated and modern. It is amusing, but also worrying, how the same issues return over and over again. This is the story of a profound revolution in the way biologists explore life's history, understand its evolutionary processes, and reveal its diversity. How many species and genera of prokaryotes exist? The late 1970s results were met with scepticism, and this part of the book contains a very detailed discussion. Populations that we might want to label species do not have isolated gene pools, and mutations within these populations are probably not the primary source of evolutionary novelty.

This is the story of a profound revolution in the way biologists explore life's history, understand its evolutionary processes, and reveal its diversity. Professor Sapp held the Canada Research Chair Tier 1 in the History of the Biological Sciences at the University of Québec at Montréal from 2001 to 2003 of which he remains an Associate; he returned to the Biology Department at York University. Jan Sapp is Professor of Biology and History at York University, Toronto, where he teaches processes of evolution and the history of biology. It is about life's smallest entities, deepest diversity, and greatest cellular biomass: the microbiosphere. About half of the book is devoted to this three decade long process. However, science has gone further, Woese's work remains very important, subsequent work has brought up questions, particularly the problem of lateral gene transfer and the discovery of several eukaryote-like properties of planctomycetes, a phylum of the domain Bacteria. Revisiting the history of microbiology for the first time from the perspective of evolutionary biology, Sapp shows why classical Darwinian conceptions centering on questions of the origin of species were forged without a microbial foundation, why classical microbiologists considered it impossible to know the course of evolution, and classical molecular biologists considered the evolution of the molecular genetic system to be beyond understanding.

In so doing, he examines-from Lamarck to the present-the means of pursuing the evolution of complexity, and of depicting the greatest differences among organisms. The general conclusion at the time was that the study of bacterial evolution simply was unapproachable and therefore that microbial taxonomy could not be based on evolutionary relationships. The data that arrived with the genome sequencing projects did not fit traditional evolutionary thinking. They argued that we had to reconsider how we think about microbial evolution. It is about life's smallest entities, deepest diversity, and greatest cellular biomass: the microbiosphere. In telling this stirring story of scientific iconoclasm, this book elucidates how the new evolutionary biology arose, what methods and assumptions underpin it, and the fiery controversies that continue to shape biologists' understanding of the foundations of evolution today. However, by the 1990s, the approach was widely accepted and had produced large phylogenetic trees including all forms of life.

Jan Sapp introduces us to a new field of evolutionary biology and a new brand of molecular evolutionists who descend to the foundations of evolution on Earth to explore the origins of the genetic system and the primary life forms from which all others have emerged. Yet, scientists relate to this new knowledge radically differently. Revisiting the history of microbiology for the first time from the perspective of evolutionary biology, Sapp shows why classical Darwinian conceptions centering on questions of the origin of species were forged without a microbial foundation, why classical microbiologists considered it impossible to know the course of evolution, and classical molecular biologists considered the evolution of the molecular genetic system to be beyond understanding. Evolution by leaps seems to occur regularly in the microbial world where molecular evolutionists have shown the inheritance of acquired genes and genomes are major modes of evolutionary innovation. Revisiting the history of microbiology for the first time from the perspective of evolutionary biology, Sapp shows why classical Darwinian conceptions centering on questions of the origin of species were forged without a microbial foundation, why classical microbiologists considered it impossible to know the course of evolution, and classical molecular biologists considered the evolution of the molecular genetic system to be beyond understanding. With such awareness, we can avoid conclusions based on pregenomic views of microbial evolution as well as jumping to trendy, but evolutionary unsound, interpretations.

Jan Sapp's book will increase the consciousness of the intellectual baggage of evolutionary thinking that we all are carrying around. Evolution by leaps seems to occur regularly in the microbial world where molecular evolutionists have shown the inheritance of acquired genes and genomes are major modes of evolutionary innovation. The last part of the book brings us to the present day. The success of molecular phylogeny did not solve the problem of a natural classification of microbes once and for all. Evolution by leaps seems to occur regularly in the microbial world where molecular evolutionists have shown the inheritance of acquired genes and genomes are major modes of evolutionary innovation. If questions of the relationships between planctomycetes and eukaryotes can be experimentally resolved, I could see Woese and the group that resolves this problem sharing a Nobel Prize, if that comes during Woese's lifetime. It is a must-read for anyone with the slightest interest in the historical background to the current controversies regarding the role of horizontal gene transfer and how this affects the notion of a tree of life for prokaryotes.

Saltational Symbiosis, Theory in Bioscience 129 2010 : 125-133. Sapp starts off with Antony van Leeuwenhoek's observations in the 17th century and quickly leads to the germ theory in the second half of the 19th century as expected from a book covering the history of microbes. This book should be required reading for every biologist, biology major, and biology teacher. The New Foundations of Evolution takes us into a world that classical evolutionists could never have imagined: a deep phylogeny based on three domains of life and multiple kingdoms, and created by mechanisms very unlike those considered by Darwin and his followers.

That may be due to problems in culturing many of the simple life forms.

Transcending Darwinism: Thinking Laterally on the Tree of Life, History and Philosophy of the Life Sciences 31 2009 : 161-182. The real new foundations in evolution will appear only if we pay close attention to which evolutionary ideas are informing our scientific activities. In addition, insights into the seemingly endless discussions about the relationship between taxonomy and phylogenetics throughout the 20th century are offered as well as developments of ideas for the origin of life. I have read much of the secondary literature on microbial taxonomy and identification but for the first time it was fully accessible, coming to life as I turned the pages of the book. Sapp takes us back to the very beginnings of our empirical exploration of the microbiaL world, and follows every observational milestone with the deductive reasoning and often heated debates within the scientific community.

All existing eukaryotes have double membrane structures that can reasonably be considered mitochondria or reduced forms. Jan Sapp introduces us to a new field of evolutionary biology and a new brand of molecular evolutionists who descend to the foundations of evolution on Earth to explore the origins of the genetic system and the primary life forms from which all others have emerged. With an appreciation of the influences of our different standpoints, we can approach the current and future data with open eyes. Nevertheless, transfer of genetic material between bacteria was shown to be possible in the laboratory, which could explain apparently adaptive changes in nature, such as the appearance of antibiotic resistance. The use of Escherichia coli as a model system in the developing field of molecular biology in the 1950s and 1960s excluded Lamarckian mechanisms of evolution for bacteria.
