View abstract on PubMed
Summary
This summary is machine-generated.The study challenges the idea that the human language capacity evolved suddenly due to the computational properties of Merge. It argues that the atomicity of Merge does not necessitate a single-mutation scenario for language evolution.
Area Of Science
- Linguistics
- Evolutionary Biology
- Computational Linguistics
Background
- Theoretical linguists propose a sudden emergence of human language capacity based on computational properties.
- The minimalist operation Merge, crucial for hierarchical language structures, is presented as an all-or-nothing mechanism.
- This has led to a single-mutation hypothesis for the evolution of language.
Purpose Of The Study
- To critically examine the argument linking the computational atomicity of Merge to a sudden language evolution scenario.
- To evaluate the validity of inferring evolutionary steps from the formal complexity of linguistic operations.
- To challenge the justification of a single-mutation theory for language evolution based on Merge.
Main Methods
- Detailed analysis of the argument connecting Merge's properties to evolutionary scenarios.
- Examination of the logical inference from computational simplicity to evolutionary suddenness.
- Critique of the parallelism drawn between formal complexity and the number of evolutionary steps.
Main Results
- The argument that the atomicity of Merge necessitates a sudden, single-mutation evolutionary event is found to be invalid.
- The inference from the computational level (Merge's properties) to the evolutionary level (number of steps) is not logically sound.
- The study demonstrates that the simplicity of Merge does not support a sudden-emergence theory of language evolution.
Conclusions
- The proposed parallelism between Merge's atomicity and a single-mutation scenario for language evolution is flawed.
- The emergence of human language capacity cannot be justified as a sudden event solely based on the properties of Merge.
- Alternative evolutionary pathways for language must be considered beyond the single-mutation hypothesis.

Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...
According to Albert Einstein (1897-1955), free-falling and feeling weightless are intrinsically linked. If a person were in free-fall under gravity, for example, diving towards the Earth from an airplane, they would feel completely weightless. Similarly, a person descending in a lift may feel partially weightless. Broadly speaking, it is assumed that an object in a uniform gravitational field and an object undergoing constant acceleration in the absence of gravity are under the same...
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.
The structures that arise from convergent evolution are called analogous structures. They are similar in function even if they are dissimilar in structure. Further, structures can be analogous while...
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
