Classified with lizards in the order Squamata, snakes represent a lizard that, over the course of evolution, has undergone structural reduction, simplification, and loss as well as specialization.
Therefore, it has been suggested that the segmental set of serotonin-immunoreactive neurons has undergone a step-wise simplification during arthropod evolution and individually identifiable neurons have been proposed as an evolutionary novelty of myriapods and tetraconates (in support of the Mandibulata hypothesis) (e.g. [ 10, 40]).
Ang 洪惟仁 (2003, 2012) argued that [dz] is the oldest realization of /dz/ but has undergone some dialect-dependent simplifications due to articulatory difficulty.
As shown in Fig. 1, [dz] was the original realization for /dz/ but has undergone some dialect-dependent simplifications due to its articulatory difficulty.
These different observations are not in accord with the idea that NCLDV, and especially the giant representatives of the family, have undergone a simplification process by loosing a large array of genes from a complex cellular ancestor [ 8].
Following the generally accepted opinion that Chelicerata represents the plesiomorphic mode of neurogenesis, whereas the Hexapoda and Malacostraca represent a rather derived mode, the serotonergic systems of the ventral nerve cord seem to have undergone a simplification process.
bulgaricus genome has undergone a rapid reductive evolution as gene loss and metabolic simplification, known to be the central trend of evolving LABs [5].
