Humans recognize shape, whereas computer programs like Fisher-Mahalanobis Discriminant Analysis commonly are prone to recognize by size. Has-or-has-not produces rather few characters. The morphogenesis of ciliates uses random distribution statistics for the taxonomy of ciliates, although the cell is cyclic and determined. The arithmetic mean (AM), the standard deviation (SD) and the mode (M) are determined, and so are genetic factors including clonal cycle effects. Some cell regulation has long been developed in Paramecium by James D. Berger and his associates. It is now suggested that the mode of distance units with 10 % percentiles is the most informative and logically applicible descripter. Trigonometric variables should be used in morphometrics.
