A theory from Karl Bogislaus Reichert and Ernst Gaupp regarding the homology of incus and malleus, with the quadrate and articular, respectively.
Reichert and Gaupp’s theory is credited for their thesis that mammalian middle ossicles are derivatives of the reptilian jaw bones. Despite some opposition to this theory, the contribution to the scientific knowledge is widely accepted.
What the Theory Postulates
This theory was firstly established by Karl Bogislaus Reichert (see Reichert’s cartilage) and then further elaborated by Ernst Gaupp, founder of modern studies in craniogenesis. The theory is regarding the origin of the mammalian ossicles of the ear and the relationship between the reptilian jaw bones and mammalian middle ear bones in 1837 (World Heritage Encyclopedia 2017). Specifically, the theory posits that the malleus and...
