homology notes

The 'new animal phylogeny' reveals that many of the groups known to biomineralize sit among close relatives that do not, and it favours an interpretation of convergent or parallel evolution for biomineralization in animals. (...) Whether this 'biomineralization toolkit'of genes reflects a parallel co-option of a common suite of genes or the inheritance of a skeletogenic gene regulatory network from a biomineralizing common ancestor remains an open debate.[debated][VHOG]
