Surf these sites: A Theory on the Origin of Life -- Posted by David Bell, a retired engineer, suggesting the mechanism of a single dynamic event by which DNA might have been instigated by alpha radiation. Amos'' WWW links page -- Part of the ExPASy Molecular Biology Server, this extensive list contains almost exclusively pointers to information sources for life scientists with an interest in biological macromolecules. Bioinformatics: Phylogenetic Analysis -- Phylogenetic analysis discussed as the reconstruction of evolutionary genealogies of species based on morphological similarities, generating a a `cladogram'' or `phylogenetic tree'', a hierarchical branching diagram of species relationships. Contains a good discussion, links to software, and references. CMSMBR Molecular Evolution - Phylogeny -- Small list of links to tools and resources for phylogenetic analyses of evolution. Farside Research Institute -- The evolution group of the Institute of Molecular BioSciences at Massey University, Palmerston North, New Zealand. International Society of Molecular Evolution -- A non-profit organization founded in 1993, and incorporated in 1997, to facilitate the communication and publishing of information in the field of Molecular Evolution. Membership benefits include a personal subscription to the Journal of Molecular Evolution (JME), the official Journal of the Society, and discounts for the international meetings organized by the Society. Introduction to Phylogeny -- UCMP Exhibit Halls: PHYLOGENY. The ancestor/descendant relationships which connect all organisms that have ever lived. Models of Molecular Evolution and Phylogeny -- Produced by Nikos Drakos of the Computer Based Learning Unit at the University of Leeds, this is a review of some of the DNA base substitution and amino acid replacement models most widely used, along with some of their most important current developments. Maximum likelihood inference using these models is briefly introduced as one statistical method used to draw evolutionary inferences, and as a fundamental part of the procedure for comparing the models. The site concludes with speculations on the future course of molecular evolutionary analyses. Molecular Evolution at Dalhousie University Department of Biochemistry -- This laboratories research focuses on the early evolution of genes and genomes, using standard methods of molecular genetics and sophisticated computer algorithms to reconstruct phylogenies from gene sequences and to understand genome evolution as a process. Topics considered include the following: introns, eukaryotic genome origins, gene duplications in eukaryotic nuclear genome evolution, role of lateral gene transfer in evolution, and neutral models for the evolution of molecular complexity. Contains explanation of work and bibliographies. Molecular Phylogenetics and Evolution -- This journal is dedicated to bringing Darwin''s dream–to "have fairly true genealogical trees of each great kingdom of Nature"–within grasp, and provides a forum for molecular studies that advance our understanding of phylogeny and evolution. Stuart A. Kauffman Home Page -- Abstracts and investigations on origins of life, beginning with autocatalytic sets through the mechanism of spontaneous organization. Symmetry-breaking and Molecular Evolution -- This excellent site explores the structural relationship between cosmological symmetry-breaking and the form of molecular evolution leading to biological systems on Earth. It thus forms an alternative to historical hypotheses in which the form of biogenesis is believed to be the product of a linked sequence of specific conditions, bridged by stochastic selection processes. Well-constructed, good graphics. Szostak Laboratory -- Details work exploring the evolution of novel ribozymes (deoxyribo and ribonucleic acid catalysts) from populations of random sequences, attempting to shed light on the origins of biological catalysis. The Thermosynthesis Home Page -- Thermosynthesis theory shows how organisms can use or may have used thermal cycling as an energy source-thermal cycling occurring especially in volcanic hot springs. Thermosynthesis could stepwise evolve towards photosynthesis. It may still occur in convecting aquifers on Earth, but also on the many other bodies in the Solar System where water has been found. The Tree of Life -- The Tree of Life is a project containing information about the diversity of organisms on Earth, their history, and characteristics. The information is linked together in the form of the evolutionary tree that connects all organisms to each other. William R. Atchley Group: Molecular Evolution Research -- A list of links from this research group at North Carolina State University.
