	Molecular systematics - Wikipedia, the free encyclopedia
		Molecular systematics is a phrase used to indicate a branch of the traditional field of systematics that utilizes molecular biology techniques.
		In a molecular systematic analysis, the haplotypes are determined for a defined area of genetic material; ideally a substantial sample of individuals of the target species or other taxon are used however many current studies are based on single individuals.
		Molecular systematics often uses the molecular clock assumption that quantitative similarity of genotype is a sufficient measure of the recency of genetic divergence.

	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.
		Molecular Clock Hypothesis: states that nucleotide substitutions, or amino acid substitutions if proteins are being compared, occur at a constant rate, that is, the degree of difference between two sequences can be used to assign a date to the time at which their ancestral sequence diverged.
		Furthermore, molecular clocks require calibration with fossils to determine timing of origin of clades, and thus their accuracy is crucially dependent on the fossil record, or lack thereof, for the groups under study.

	Molecular Systematics
		The rapidity of this radiation is reaffirmed by the lack of well-supported subfamilial associations in molecular studies.
		Second, if previous molecular studies are any indication, the molecular phylogeny will differ from morphological phylogenies in several respects, and this will inspire careful examination of molecular and morphological evidence.
		If no potential source of bias in the molecular data can be found, this should inspire morphologists to carefully reevaluate the characters underlying that part of their phylogeny.

		The focus of the projects varies from systematics and biogeography, e.g., clarification of relationships of certain Amazonian parakeets and South American tyrant-flycatchers and their biogeographic history, to other studies that use molecular phylogenetic techniques to understand the origin of interesting ecological diversity in birds such as that shown by brood parasites.

		Molecular sequencing illuminates the evolutionary history of the molecules themselves and, consequently, that of their host organisms.
		Molecular dating, while not always in agreement with fossil evidence, offers an opportunity for timing events that are otherwise unobservable.
		For example, it was by the molecular clock method that the branching point between chimpanzee and man was shown to be as recent as 5-8 million years ago, rather than 14-16 million years, as had been previously generally accepted (Mayr 2001, p.

	Molecular evolution - Wikipedia, the free encyclopedia
		Molecular evolution emerged as a scientific field in the 1960's as researchers from molecular biology, evolutionary biology and population genetics sought to understand recent discoveries on the structure and function of nucleic acids and protein.
		Molecular systematics has been made possible by the availability of techniques for DNA sequencing, which allow the determination of the exact sequence of nucleotides or bases in either DNA or RNA.
		An important area within the study of molecular evolution is the use of molecular data to determine the correct scientific classification of organisms.

	Molecular systematics, University of Bergen
		Systematic biology is concerned with taxonomy, the classification and identification of living organisms, phylogeny, the evolutionary history of life, and biogeography, the analysis of distributional patterns in a historical and ecological perspective.
		Systematics provides a basis for most other biological work and is essential in applied forms of biology, such as biological control and nature conservation.
		The main objective of the research programme is to broaden the horizon of systematics at the University of Bergen by developing additional competence within molecular techniques and the utilization of molecular data in systematics.

	Molecular phylogeny - Wikipedia, the free encyclopedia
		Molecular phylogeny is the use of the structure of molecules to gain information on an organism's evolutionary relationships.
		The result of a molecular phylogenetic analysis is expressed in a so-called phylogenetic tree.
		Molecular phylogeny uses such data to build a "relationship tree" that shows the probable evolution of various organisms.
