Adaptation/brain/language/Deacon: when it comes to whether the brain adapts to certain requirements of language processing and language acquisition, the following is crucial: apart from the fact that a noun remains a noun and a change of time a change of time, regardless of the words involved, there must be more constant things between individuals, certain functions that are always processed in the same way in different ways under all conditions. There must be certain invariant sensory motoric or mnemonic features that could be adapted.
Such characteristics are present in the case of alarm calls from animals, e.g. when a distinction is made between enemies on the ground and enemies of the air.
Symbols/symbolic learning/adaptation/Deacon: it is precisely the complex structure that forms symbols among each other that make it impossible for them to be genetically assimilated. (See also Symbols/Deacon). Most grammatical operations have no direct connection to things in the world. Therefore, there is hardly any innate reference in the human language. The grammatical peculiarities also change from language to language, so that there is little consistency for possible adaptation.
Deep structure: maybe this is what is open to adaptation? In order to adapt a function, it is not necessary for a certain place in the brain to remain constant for this function. Newer theories speak more of "language programs" and "data structures".
The way these structures are distributed in the brain should remain invariant when assimilated in an evolutionary process.
Speech processing: interestingly, it is not the logical operations but the analysis of the physical signals that are assigned to specific brain regions. This has major consequences. The grammatical structures are the ones that have had the least chance of establishing a fixed place in the brain for their processing._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
