Lamarck claimed that species could transform through the influence of the environment, while Saint-Hilaire argued in 1820 that two of Cuvier's branches, the molluscs and radiata, could be united via various features, while the other two, articulata and vertebrates, similarly had parallels with each other.

From this point of view, several common characteristics still support the Articulata hypothesis segmented body; paired appendages on each segment; pairwise arrangement of waste-elimination organs in each segment; and above all, a rope-ladder-like nervous system based on a double nerve strand lying along the belly.

Another very distinct and only distantly related species, formerly treated as " Thuja orientalis ", is now treated in a genus of its own, as " Tetraclinis articulata " ( Greek " ????, ???

The " Magazine of Natural History " of 1829 expressed surprise at the long interval between the first and second editions, surmising that there were too few scientific readers in France, apart from those in Paris itself; it notes that while the first volume was little changed, the treatment of fish was considerably altered in volume II, while the section on the Articulata was greatly enlarged ( to two volumes, IV and V ) and written by M . Latreille.
