Phylogenetics

In biology, phylogenetics ( /faɪlɵdʒɪˈnɛtɪks/) is the study of evolutionary relationships among groups of organisms (e.g. species, populations), which are discovered through molecular sequencing data and morphological data matrices. The term phylogenetics derives from the Greek terms phylé (φυλή) and phylon (φῦλον), denoting "tribe","clan", "race" and the adjectival form, genetikós (γενετικός), of the word genesis (γένεσις) "origin," "source," "birth". The result of phylogenetic studies is a hypothesis about the evolutionary history of taxonomic groups: their phylogeny.
