These authors also suggested placing them among the earliest active predator metazoans and argued that the ancestral chaetognaths were planktonic with possible ecological preferences for hyperbenthic niches close to the sea bottom. Today, the taxon Chaetognatha comprises more

This does not imply, however, that the relationships between ontogeny and phylogeny are always easy to discover or that these follow simple and perhaps universal principles such as Haeckel’s (1866) “biogenetic law.” Haeckel’s recapitulationist views

In addition, homology is hard to pin down mechanistically. Apparently, homology is among the concepts biologists have a hard time living with but certainly can’t live without. This situa
