 While analyses of morphology suggest a close relationship between Homarinus and Homarus , molecular analyses using mitochondrial DNA reveal that they are not sister taxa . Both genera lack ornamentation such as spines and carinae , but are thought to have reached that state independently , through convergent evolution . The closest living relative of Homarus is Nephrops norvegicus , while the closest relatives of Homarinus are Thymops and Thymopides .
