DEVELOPMENT CLUES. “During development, infolding of the olfactory placodes occurs, bringing the medial olfactory processes to form the septolateral cartilage while the lateral olfactory processes form the alar cartilages. The olfactory fascia unites these cartilages to the olfactory mucosa, that stays separated from brain by the cartilaginous olfactory capsule (the ethmoid bone forerunner).” http://www.wjgnet.com/esps/DownLoadFile.aspx?Type=Digital&SubType=2&DOI=10.5319%2Fwjo.v6.i2.33&FilePath=Pub%5C10.5319%5Cv6%5Ci2%5CWJO-6-33.doc View in LinkedIn

SMELL FIRST. “The median nasal septum develops inferiorly from the roof of the nasal cavity. These valuable embryologic data do not explain the complex intricacy of the many anatomical structures comprising the nose. The evo-devo theory offers a rational explanation to this complex anatomy. Phylogenically, the nose develops as an olfactory organ in fish before becoming respiratory in tetrapods.” http://www.wjgnet.com/esps/DownLoadFile.aspx?Type=Digital&SubType=2&DOI=10.5319%2Fwjo.v6.i2.33&FilePath=Pub%5C10.5319%5Cv6%5Ci2%5CWJO-6-33.doc View in LinkedIn

THE HUMAN NOSE. “In humans, the mammalian olfactory chambers are transformed into olfactory clefts and lateral masses of the ethmoid, and the transverse lamina separating the olfactory and respiratory noses has disappeared.” http://www.wjgnet.com/esps/DownLoadFile.aspx?Type=Digital&SubType=2&DOI=10.5319%2Fwjo.v6.i2.33&FilePath=Pub%5C10.5319%5Cv6%5Ci2%5CWJO-6-33.doc View in LinkedIn

THE VERTEBRATE NOSE. “In vertebrates, the olfactory placodes give rise to the fibrocartilaginous nose made of alar and septolateral cartilages, olfactory mucosa and the olfactory fascia; the respiratory nose develops by evolutionary remodeling of the palatal bones under the olfactory nose.” http://www.wjgnet.com/esps/DownLoadFile.aspx?Type=Digital&SubType=2&DOI=10.5319%2Fwjo.v6.i2.33&FilePath=Pub%5C10.5319%5Cv6%5Ci2%5CWJO-6-33.doc View in LinkedIn

TWO ORGANS IN ONE. “The intricate and elaborate anatomy of the human nose can be best understood by gathering knowledge in evolution and development. Phylogenically and ontogenically, the nose results from two distinct entities: The olfactory and respiratory organ.” http://www.wjgnet.com/esps/DownLoadFile.aspx?Type=Digital&SubType=2&DOI=10.5319%2Fwjo.v6.i2.33&FilePath=Pub%5C10.5319%5Cv6%5Ci2%5CWJO-6-33.doc View in LinkedIn

SO ENDS this first of two weekends devoted to an evo-devo analysis of the human nose. As a case study, it is an exemplary example of the power of combining evolution and development as tools to untangle a complex dual function organ like the nose. While you may not have spent sleepless nights worrying about these questions, this very elegant article guides you effortlessly between arcane medical school anatomy, involuted embryology and taxa surveys to answer this question. Walk in somebody else’s shoes a mile or two. View in LinkedIn

"TRADITIONAL KNOWLEDGE seeks to comprehend such complexity by operating from a different epistemological basis. It eschews reductionism, placing little emphasis on studying small parts of the ecological system in isolation from the dependent interacting biophysical milieu. It also recognizes that the reductionist approach is impractical in the extreme: even if one were to know everything there was to know about everything of importance under all possible combinations and permutations of variability, such an immense database would be impossible to work with in practice." https://lnkd.in/dvpgYsT View in LinkedIn
