- Studies of the fossil record indicate the sequence in which the shape of a phenotype has been modified during phylogeny. These data can provide a valuable starting point for theoretical embryology. Any theory which accounts for the development of a particular shape or pattern in recent animals should, by equivalent modifications, be able to account for the phylogenetic sequence of shapes. This argument is illustrated by the evolution and development of patterns in dentitions.
