The acknowledgement of an indirect relationship between genes and traits, and; The rejection of the existence of 'special' genes for language, that is, the rejection of the need for a specifically linguistic genotype; Based on this, Lenneberg goes on further to claim that no kind of functional principle could be stored in an individual's genes, rejecting the idea that there exist genes for specific traits, including language. In other words, that genes can contain traits. He then proposed that the way in which genes influence the general patterns of structure and function is by means of their action upon ontogenesis of genes as a causal agent which is individually the direct and unique responsible for a specific phenotype, criticizing prior hypothesis by Charles Goodwin.
== Recent developments ==
=== Generative procedure accepted at present & its developments === In biolinguistics, language is recognised to be based on recursive generative procedure that retrieves words from the lexicon and applies them repeatedly to output phrases. This generative procedure was hypothesised to be a result of a minor brain mutation due to evidence that word ordering is limited to externalisation and plays no role in core syntax or semantics. Thus, different lines of inquiry to explain this were explored. The most commonly accepted line of inquiry to explain this is Noam Chomsky's minimalist approach to syntactic representations. In 2016, Chomsky and Berwick defined the minimalist program under the Strong Minimalist Thesis in their book Why Only Us by saying that language is mandated by efficient computations and, thus, keeps to the simplest recursive operations. The main basic operation in the minimalist program is merge. Under merge there are two ways in which larger expressions can be constructed: externally and internally. Lexical items that are merged externally build argument representations with disjoint constituents. The internal merge creates constituent structures where one is a part of another. This induces displacement, the capacity to pronounce phrases in one position, but interpret them elsewhere. Recent investigations of displacement concur to a slight rewiring in cortical brain regions that could have occurred historically and perpetuated generative grammar. Upkeeping this line of thought, in 2009, Ramus and Fishers speculated that a single gene could create a signalling molecule to facilitate new brain connections or a new area of the brain altogether via prenatally defined brain regions. This would result in information processing greatly important to language, as we know it. The spread of this advantage trait could be responsible for secondary externalisation and the interaction we engage in. If this holds, then the objective of biolinguistics is to find out as much as we can about the principles underlying mental recursion.
=== Human versus animal communication === Compared to other topics in linguistics where data can be displayed with evidence cross-linguistically, due to the nature of biolinguistics, and that it is applies to the entirety of linguistics rather than just a specific subsection, examining other species can assist in providing data. Although animals do not have the same linguistic competencies as humans, it is assumed that they can provide evidence for some linguistic competence. The relatively new science of evolutionary developmental biology that suggests everyone is a common descendant from a single tree has opened pathways into gene and biochemical study. One way in which this manifested within biolinguistics is through the suggestion of a common language gene, namely FOXP2. Though this gene is subject to debate, there have been interesting recent discoveries made concerning it and the part it plays in the secondary externalization process. Recent studies of birds and mice resulted in an emerging consensus that FOXP2 is not a blueprint for internal syntax nor the narrow faculty of language, but rather makes up the regulatory machinery pertaining to the process of externalization. It has been found to assist sequencing sound or gesture one after the next, hence implying that FOXP2 helps transfer knowledge from declarative to procedural memory. Therefore, FOXP2 has been discovered to be an aid in formulating a linguistic input-output system that runs smoothly.
=== The integration hypothesis === According to the Integration Hypothesis, human language is the combination of the Expressive (E) component and the Lexical (L) component. At the level of words, the L component contains the concept and meaning that we want to convey. The E component contains grammatical information and inflection. For phrases, we often see an alternation between the two components. In sentences, the E component is responsible for providing the shape and structure to the base-level lexical words, while these lexical items and their corresponding meanings found in the lexicon make up the L component. This has consequences for our understanding of: (i) the origins of the E and L components found in bird and monkey communication systems; (ii) the rapid emergence of human language as related to words; (iii) evidence of hierarchical structure within compound words; (iv) the role of phrases in the detection of the structure building operation Merge; and (v) the application of E and L components to sentences. In this way, we see that the Integration Hypothesis can be applied to all levels of language: the word, phrasal, and sentence level.
