relationship loss: subclass specialized connective tissue (AAO:0000571)[AAO]

Portion of tissue which is calcified connective tissue making up the structural elements of the skeletal system.[TAO], Also called osseous tissue, (Latin: os). Is a type of hard endoskeletal connective tissue found in many vertebrate animals. Bone is the main tissue of body organs that support body structures, protect internal organs, (in conjunction with muscles) facilitate movement; and are involved with cell formation, calcium metabolism, and mineral storage.[AAO], Skeletal element that is composed of bone tissue.[VSAO]

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]
