Summary Evolutionary studies, one of the main aims of “biosystematics” frequently do not provide the practical information required for classification. A truly phyletic classification is probably unattainable in view of the sheer numbers of organisms systematists have to deal with. Chromosomal changes, however, are often of importance as characters in more conventional taxonomy. The evolutionary direction of the changes is mostly difficult to assess.
