The term monophyly, or monophyletic, derives from the two Ancient Greek words μόνος (mónos), meaning "alone, only, unique", and φῦλον (phûlon), meaning "genus, species", [4] [5] and refers to the fact that a monophyletic group includes organisms (e.g., genera, species) consisting of all the descendants of a unique common ancestor.
Computational phylogenetics can be used to investigate a language as an evolutionary system. The evolution of human language closely corresponds with human's biological evolution which allows phylogenetic methods to be applied. The concept of a "tree" serves as an efficient way to represent relationships between languages and language splits.

In linguistics, language classification is the grouping of related languages into the same category. There are two main kinds of language classification: genealogical ...
The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).
This is a list of ancestor languages of modern and ancient languages, detailed for each modern language or its phylogenetic ancestor disappeared. For each language, the list is generally limited to the four or five immediate predecessors.
Also called a monophyletic group. A phylogenetic grouping of organisms that consists of a single common ancestor and all of its lineal descendants, and which by definition is monophyletic. The common ancestor may be an individual organism, a population, a species, or any other taxon; any and all members of a clade may be extant or extinct.
Again, while not disagreeing with the notion that only monophyletic groups should be named, empiricist systematists counter this ancestry essentialism by pointing out that pelycosaurs are recognized as paraphyletic precisely because they exhibit a combination of synapomorphies and symplesiomorphies indicating that some of them are more closely ...
