	Molecular systematics - Wikipedia, the free encyclopedia
		Molecular systematics is a phrase that might be used to indicate that branch of the traditional field of systematics that utilizes data obtained by "molecular techniques".
		Molecular systematics is an essentially cladistic approach: it assumes that classification must correspond to phylogenetic descent, and that all valid taxa must be at least paraphyletic and preferably monophyletic.
		Molecular systematics often uses the molecular clock assumption that quantitative similarity of genotype is a sufficient measure of the recency of genetic divergence.

	Systematics
		Systematics is the study of the historical relationships of groups of biological organisms -- the recognition and understanding of biodiversity.
		Systematics differs from ecology in that the latter is concerned with the interactions of taxa and individuals in a particular time, while the former is concerned only with the relationships of hierarchic lineages through time.
		Systematics includes the processes of identifying the basic systematic unit (the species), discovering the patterns of relationships of species at successively higher levels, building classifications based on these patterns and naming appropriate taxa (taxonomy), and the application of this pattern knowledge to studying changes in organismal features through time.

	Phylogenetic Systematics
		Systematics is an attempt to understand the evolutionary interrelationships of living things, trying to interpret the way in which life has diversified and changed over time.
		While classification is primarily the creation of names for groups, systematics goes beyond this to elucidate new theories of the mechanisms of evolution.
		Systematics, then, is the study of the pattern of relationships among taxa; it is no less than understanding the history of all life.

		Systematics is the scientific study of organismic diversity, principally the history of species and the factors responsible for the origin and subsequent evolution of that diversity.
		Systematics includes the study of both natural patterns and processes, and as might be expected it is rich in concepts and methodology, perhaps more so than any other science.
		Phylogenetic systematics, or cladistics as it is usually labelled, involves the discovery of the species genealogy and the formulation of a consistent hierarchy of proper names, a monophyletic taxonomy.

	Systematics and Biological Characteristics
		Taxonomy, that component of systematics specifically focusing on the theory and practice of classification, is not clearly separable and both are frequently used interchangeably by biologists.
		Systematics plays a central role in biology by providing the means for characterizing the organisms that we study.

	Systematics - Wikipedia, the free encyclopedia
		In biology, systematics is the study of the diversity of organism characteristics, and especially how they relate evolutionarily.
		The term "systematics" may or may not overlap with "taxonomy" which concerns itself with scientific classification of species and other taxa.

	What is Systematics?
		Systematics is central to all of biological science, as it provides the fundamental framework that allows scientists to compare their results amongst all living things.
		Systematics provides the knowledge and skills needed to discover and utilise new natural resources, as knowledge of the variety and inter-relationships of organisms has important applications in medicine, agriculture and industry.
		Systematics provides the knowledge and skills needed to catalogue and conserve the Earth's biodiversity, in particular the recognition of threatened species, the identification of areas of high diversity, and an understanding of ecosystem functions (such as the regulation of atmospheric gases, climatic effects, or the generation and maintenance of soil).

	Nearctica - Evolution - Systematics - A Simple Introduction to Systematics
		Systematics is the underlying cornerstone of all biology.
		Systematics deals with the description of biological species, the development of classifications of these species so that information about them may be readily retrieved, and the study of the evolutionary relationships between them.
		Evolutionary systematics is just a fancy name for the way classifications were constructed before the days of modern phylogenetic systematics.

	Systematics
		Given the central role of systematics, there is hardly an area of paleontology on which it does not impact.
		The shift in museums away from systematic toward theme-based interactive exhibits means that many such institutions no longer regard their collections as a resource for ìfront-of-houseî displays.
		This is fuelled by some recognition of the importance of systematic paleontology by the wider scientific community, and predicated by awareness of the current global biodiversity crisis and the vulnerability of the planet to extinction events.

	Untitled Document
		The discipline that has been called Systematics serves as a bridge between our limited and only implicit grasp of structure and the concrete experience, by introducing certain simplifications which enable us to proceed by way of an integrative progression.
		Systematics is the mental tool whereby we study organized complexities and this paper will give a short account of the present state of its development.
		The discipline of Systematics is offered as a contribution towards the development of that integrative understanding which is sorely needed for the meeting of the problems and tasks of our time.

	Phylogenetics Factsheet
		Systematics reaches beyond taxonomy to elucidate new methods and theories that can be used to classify species based on similarity of traits and possible mechanisms of evolution, a change in the gene pool of a population over time.
		Phylogenetic systematics is that field of biology that does deal with identifying and understanding the evolutionary relationships among the many different kinds of life on earth, both living (extant) and dead (extinct).
		Systematics describes the pattern of relationships among taxa and is intended to help us understand the history of all life.

		Systematics deals with the recognition, relationships, classification, and organization of groups of any kind of things, which could include languages, organisms, or stamps.
		When doing systematics the problems are generally approached in the form of a question: when given three organisms, e.g.
		Two other commonly recognized schools of systematics other than cladistics, which groups organisms only by shared derived characters, are: evolutionary systematics, which groups by shared derived and shared primitive characters; and phenetics, which groups by convergent characters, shared derived characters, and shared primitive characters.

	The DuVersity; Gurdjieff, Bennett, Systematics and the Enneagram - Solioonensius Talk - NY 1995
		Systematics was developed by the mystic, research scientist and philosopher, John Bennett (1897-1974).
		The main properties of what is called a 'system' in systematics are said to arise entirely from the NUMBER of elements of which it is composed.
		Other streams of thought have concerned themselves with much the same issues as systematics: Jung, and his successor Marie von Franz in particular, in psychology, religion and divination (synchronicity); René Guenon in occult studies; Eliot Jacques in management and organizations; Arthur Young and David Foster in cosmology; Joseph Rael in the Amerindian tradition.

		The course is designed to promote the themes common among taxonomic disciplines, as is currently emphasized by interdisciplinary systematic societies such as the Society for Systematic Biology, the Willi Hennig Society, and the Systematics Association.
		Weeks 6-9 investigate several contemporary problems in systematic theory: ways of evaluating the quality of systematic results in morphological and molecular data, the Comparative Method, cladistic biogeography, coevolution, species concepts, classification and the nomenclatorial codes.
		The final week wraps up the course with a philosophical discussion of systematics as a science that is intended to tie together all the other pieces.

	John Alroy's research interests: Systematics (Site not responding. Last check: 2007-11-06)
		My work in systematics is both theoretical and empirical.
		It requires assuming either that the graphs are ahistorical (e.g., when analyzing gene flow patterns among populations); that the reticulations represent convergence, not similarity by descent; or that the objects in the graph (taxa in phylogenetics, areas in biogeography) are evolutionarily static except during lineage-splitting events (= punk eke).
		My empirical work in systematics focuses on the hipparionines, an extinct tribe of medium- to small-sized three-toed horses that was very diverse in the Late Miocene (about 11 - 5 Ma).
