| Furthermore, foraminiferal growth is often strongly allometric, and in many foraminifers the shape of the chamber changes during ontogeny. |
| Selection may act to modify ontogeny and ultimately determine morphology and function. |
| In the normal lymphoid ontogeny, genomic recombinations occur in a tightly regulated sequence and require an enzyme called recombinase. |
| The ontogeny and dimorphic features of many early Middle Ordovician ostracode species are still poorly known. |
| Discuss in detail a good example of recapitulation, showing how the stages of ontogeny parallel those of phylogeny. |
| How can changes in an ancestral ontogeny be reconstructed, since the ancestors of most craniate radiations are extinct? |
