recognized in the fossil record are relative to timescale. A new
categorization of regimes of cladogenetic size change is proposed: a presented
scheme includes seventeen types. At random distribution the pure, single-cause
regimes are rare (0.01 probability of appearance) while mixed regimes,
resulting from two causes are more frequent (0.115 probability of appearance).
Some regimes seem to be not randomly distributed. |
