Definition

Glossary of "Cladistics (2nd ed.)" by Kitching et al. (1998)

• An iterative method of character analysis that attempts to bring the order of multistate characters into conformity with the hierarchy inherent in the rest of the data. TSA begins with the construction of an initial transformation series for each multistate character. The data set is then analysed to find the most parsimonious cladograms. Any transformation series that conflict with these cladograms are recoded to conform to adjacent positions on the cladogram. The data set is then recoded and re-analysed to obtain a new set of most parsimonious cladograms. This process is repeated until both the topologies of the most parsimonious cladograms and the transformation series stabilize.
