The tree model has been commonly used for expressing the genetic relationship of languages. However, there are various aspects of linguistic relationship that cannot be expressed, or may even make a conflict with what is expressed and implied in such a model. In this symposium, with specialists of other disciplines such as cladistics, biology, genetics, which use diagrams to express "relationships" of the targeted objects, we will evaluate, and examine what it means to apply a "tree model" to express linguistic relationships, and what the pitfalls are in doing so.
