‘Tempo’ refers to the rate of evolution, the rate of phenotypic change either within lineages or expressed as averages within major taxonomic groups. ‘Mode’ refers to the pattern of evolution – whether it is continuous or episodic; whether it is primarily phyletic (within-lineage) or proceeds mostly by lineage-splitting; whether it shows directional trends or not; and whether it proceeds by small steps or sudden jumps.
