Of your patella in Metatheria that could have ramifications for all of Mammalia/Mammaliaformes. Very first, Szalay Sargis (2001; pp. 16465) reported the presence of an ossified patella in older folks of Didelphis virginiana in their study of an ontogenetic series from this species. They stated (p. 165) “In older individuals there’s occasionally an elongated and smaller sesamoid ossification inside the tendon of your quadriceps femoris exactly where it crosses the knee joint when the knee is flexed”. Nevertheless, this observation was not documented with illustrations or photographs (specifically tissue histology or x-rays) and hence remains a tantalizing anecdote. Similarly, Owen (1866) commented that some marsupials had no ossifications in their patellar tendon but others had “only some irregular specks of ossification” and also a “distinct but small bony patella inside the Macropus Bennettii”. In GW0742 contrast, Reese et al. (2001) and Holladay et al. (1990), respectively sampled 61 specimens (39 adults) from 30 PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/20015762 species of marsupials and 3 macropodid specimens (of unknown maturity), documenting no ossified patellae except as noted in bandicoots, and their studies made use of clear approaches for identifying ossified tissues. It remains probable that patellar ossification occurs variably in older people amongst Metatheria, which would help explain its patchy description in identified taxa. If the latter predicament will be the case (i.e. the literature is unclear about patellar ossification in marsupials since they have more inherent variability), then it relates to a second dilemma, a cladistic among character coding and transformational homology (sensu Brower Schawaroch, 1996; Pinna, 1991). Really should character states of the patella in metatherians, and even all mammals and their kin, be coded as an ordered transformational series like absent (0), fibrocartilaginous (1) or ossified (two), or as an unordered seriesSamuels et al. (2017), PeerJ, DOI 10.7717/peerj.3103 20/(i.e. ought to evolutionary steps be needed to go from 0 as two measures, or unordered enabling 0 transformations as one step) We chose the unordered character option by default for all crown group mammals, but where relevant clarify how an ordered selection changed (or did not alter) our benefits. An endochondral ossification of the bony patella is particular, but a fibrocartilaginous or otherwise soft tissue composition on the patella (coded as state 1) in adults isn’t unambiguously the vital (i.e. ordered) evolutionary precursor character state-to-state two (ossified patella in adults). The option to each of those challenges lies in additional developmental information for the patella (bony and otherwise) in diverse mammalian species, in addition to additional scrutiny with the adult morphology in extant and fossil Mammalia (especially Metatheria). As noted briefly inside the Introduction, lots of marsupials possess a primarily fibrocartilaginous patelloid in spot of an ossified patella and some other mammals could have a “suprapatella”. The developmental and evolutionary relationships of those structures remain somewhat unclear, particularly as some marsupials with an ossified patella (e.g. bandicoots) also possess a patelloid (Reese et al., 2001), suggesting that the patelloid will not be developmentally equivalent to the patella in marsupials (Vickaryous Olson, 2007). If so, this would indicate independent evolutionary histories of those two structures. Additional perform is essential to clarify the relationships from the patelloid and suprapatella at leas.
