Abstract
In biology, phylogenetics is the study of evolutionary relatedness among various groups of organisms (for example, species or populations), which is discovered through molecular sequencing data and morphological data matrices. The term phylogenetics is of Greek origin from the terms phyle/phylon (quan/pukov), meaning "tribe, race" and genetikos (yEVETIKóc), meaning "relative to birth" from genesis (yéveaç, "birth"). Taxonomy, the classification, identification and naming of organisms, has been richly informed by phylogenetics but remains methodologically and logically distinct. The fields overlap however in the science of phylogenetic systematics-often called "cladism" or "cladistics"-where only phylogenetic trees are used to delimit taxa, which represent groups of lineage-connected individuals. In biological systematics as a whole, phylogenetic analyzes have become essential in researching the evolutionary tree of life. Evolution is regarded as a branching process, whereby populations are altered over time and may speciate into separate branches, hybridize together, or terminate by extinction. This may be visualized in a phylogenetic tree. The problem posed by phylogenetics is that genetic data are only available for living taxa and the fossil records (osteometric data) contain less data and more-ambiguous morphological characters.
