Cladistics is defined as nested hirarchy of traits, this nested hirarchy takes into account the fact, that traits are inheritable and constructs a line of ancestry from the earliest ancestor with the basic set of pleisiomorphic traits inherited to todays taxa via intermediate generations with added synapomorphic traits over time.
