Comparative developmental studies have revealed a rich array of details about the patterns and processes of morphological change in animals and increasingly in plants. But, applying these insights to the study of major episodes of 演化ary innovation requires understanding how these novel morphologies become established and sufficiently abundant (either as individuals within a 物種 or as a clade of 物種) to be preserved in the fossil record, and, in many cases, to influence ecological processes. 演化ary novelties may: (1) disappear without changing the 物種; (2) be associated with the generation (through selection or drift) of a new 物種; and if the latter (3) may or may not become ecologically significant. Only the latter are commonly preserved in the fossil record. These alternatives mirror the disti
