Abstract

A survey of brachiopod genera along lines currently adopted by students of evolution suggests that for this phylum at least the raw data can change significantly from year to year dependent upon systematic opinion and regional influences, and that even if such data are accepted as reasonable reflections of brachiopod evolution they lead to conclusions different from those published for other phyla.
