Phylogeny and beyond: Scientific, historical, and conceptual significance of the first tree of life

The way in which this monumental discovery was made, its context within the historical development of evolutionary thought, and how it has impacted the authors' understanding of the emergence of life and the characterization of the evolutionary process in its most general form are described.

The Origin and Nature of Life on Earth: The Emergence of the Fourth Geosphere

Uniting the conceptual foundations of the physical sciences and biology, this groundbreaking multidisciplinary book explores the origin of life as a planetary process. Combining geology,

La evolución molecuLar y los primeros seres vivos

El reconocimiento de que los genomas son documentos histori- cos de los cuales se puede extraer informacion evolutiva ha incrementado el margen de los estudios filogeneticos a muy alto nivel. El

Looking in the right direction

This essay discusses Carl Woese's vision of evolution, one which transcends population genetics, and which has ramifications not only for the understanding of the origin of life on Earth and elsewhere, but also for the authors' understanding of biology as a novel class of complex dynamical systems.

The Singular Quest for a Universal Tree of Life

Carl Woese developed a unique research program, based on rRNA, for discerning bacterial relationships and constructing a universal tree of life and brought together diverse evidence to support the rRNA evidence for the fundamentally tripartite nature of life.

Ernst Mayr, the tree of life, and philosophy of biology

It is shown how Mayrian evolutionary biology excludes numerous forms of life and many important evolutionary processes, and an alternative to this dichotomy is a multidimensional continuum in which different strategies of genetic exchange bestow greater adaptiveness and evolvability on prokaryotes and eukaryotes.

Construction and deconstruction: The influence of lateral gene transfer on the evolution of the Tree of Life

This chapter sets out these shifts of construction, deconstruction and reconstruction, with an eye towards understanding the future of the tree of life.



On the Broad Classification of Organisms

A system of broad classification which recognized a plant kingdom of four divisions and an animal kingdom of ten to fifteen phyla was for many years stable and standardized. Significant changes have

Towards a natural system of organisms: proposal for the domains Archaea, Bacteria, and Eucarya.

It is proposed that a formal system of organisms be established in which above the level of kingdom there exists a new taxon called a "domain." Life on this planet would be seen as comprising three domains, the Bacteria, the Archaea, and the Eucarya, each containing two or more kingdoms.
