Definition noun 1 The study of phylogeny 2 The study of evolutionary relatedness among various groups of organism s through molecular sequencing data and morphological data matrices Supplement Phylogenetics is the scientific study of phylogeny. Phylogeny pertains to the evolutionary history of a taxonomic group of what is the definition of a covenant in the bible. Thus, phylogenetics is mainly concerned with the relationships of an organism to other organisms according to evolutionary similarities and differences.

Phylogenetics, therefore, is a part of the biological systematics, which has a wider scope. The latter involves not only the phylogenetics of organisms but also the identification and classification of organisms. It is also related to taxonomywhich is a branch of science concerned also in finding, describing, classifying, and naming organisms, including the studying of the relationships between taxa and the principles underlying such a classification.

Phylogenetics provides information to taxonomy when it comes to classification and identification of organisms. In phylogenetics, DNA sequencing methods are used to analyze the observable heritable traits. It also makes use of a phylogenetic tree which is a diagram to show the hypothetical evolutionary histories and relationships of groups of organisms based on the phylogenies of different biological species. The phylogenetic tree has been used to understand biodiversity, genetics, evolutions, and ecology of organisms.

While much progress has been made to find practical algorithms for reconstructing a phylogenetic network from a set of sequences, all attempts to endorse a pnylogenetic of phylogenetic networks strictly extending the class of phylogenetic trees with a well-founded distance measure have, to the best of our knowledge and with the only exception of the bipartition distance on regular networks, failed so far. Dispersal from other continents has also been important in the assembly of the Amazonian rainforest flora and the Australian flora.

These studies are urgent because understanding the history of biomes can both inform conservation decisions, and help predict the effects of future environmental changes at a time when biodiversity is being impacted on an unprecedented scale. Ideal study systems will phylogenteic based upon DNA sequence data from multiple loci and multiple fossil calibrations. Because of the critical role of fossils and morphological characters in assigning ages to nodes in phylogenetic trees, future studies must include careful morphological consideration of fossils and their extant relatives in a phylogenetic context.

To achieve their objectives, phylogenomics heavily depends on the accuracy of different methods to generate precise phylogenetic trees. Dated plant phylogenies for angiosperm families such as Leguminoaceae FabaceaeMelastomataceae sensu stricto, Annonaceae and Rhamnaceae indicate that long-distance, transoceanic dispersal has played an important role in shaping their distributions, and that this can obscure any effect of tectonic history, previously assumed to have been the major cause of their biogeographic patterns.
