In January 2014, Nature reported research into the Australian ghostshark genome[5] that showed they lack a single gene family that regulates the process of turning cartilage into bone, and indicates a gene duplication event gave rise to the transformation in bony vertebrates.[6]. The Australian ghostshark (Callorhinchus milii) is a cartilaginous fish (Chondrichthyes) belonging to the subclass Holocephali (chimaera).
