In his brief reply to Derrida, "Reiterating the Differences: A Reply to Derrida", Searle argued that Derrida's critique was unwarranted because it assumed that Austin's theory attempted to give a full account of language and meaning when its aim was much narrower. Searle considered the omission of parasitic discourse forms to be justified by the narrow scope of Austin's inquiry.   Searle agreed with Derrida's proposal that intentionality presupposes iterability, but did not apply the same concept of intentionality used by Derrida, being unable or unwilling to engage with the continental conceptual apparatus.  This, in turn, caused Derrida to criticize Searle for not being sufficiently familiar with phenomenological perspectives on intentionality.  Searle also argued that Derrida's disagreement with Austin turned on his having misunderstood Austin's (and Peirce's) type–token distinction and his failure to understand Austin's concept of failure in relation to performativity . Some critics  have suggested that Searle, by being so grounded in the analytical tradition, was unable to engage with Derrida's continental phenomenological tradition and was at fault for the unsuccessful nature of the exchange.
The hyoid bone is present in many mammals . It allows a wide range of tongue, pharyngeal and laryngeal movements by bracing these structures alongside each other in order to produce variation.  It is now realised that its lowered position is not unique to Homo sapiens , while its relevance to vocal flexibility may have been overstated: although men have a lower larynx, they do not produce a wider range of sounds than women or two-year-old babies. There is no evidence that the larynx position of the Neanderthals impeded the range of vowel sounds they could produce.  The discovery of a modern-looking hyoid bone of a Neanderthal man in the Kebara Cave in Israel led its discoverers to argue that the Neanderthals had a descended larynx , and thus human-like speech capabilities.   However, other researchers have claimed that the morphology of the hyoid is not indicative of the larynx's position.  It is necessary to take into consideration the skull base, the mandible and the cervical vertebrae and a cranial reference plane.
