The paper entitled “Platforms of Palaeolithic knappers reveal complex linguistic abilities” [1] submitted by C. Gaucherel and C. Noûs represents an interesting reflection about the possibilities to detect the human cognitive abilities in relation to the lithic production.

The definition and the study of human cognitive abilities during the Lower Palaeolithic it has always been a complex field of investigation. The relation between the technical skills (lithic production) and the emergence of the linguistic abilities is not easy to investigate due to the difficulty of finding objective data to refer to. The proposition, made by C. Gaucherel and C. Noûs, of a formal grammar of knapping as a method to study the syntactical organisation of the reduction sequences, constitute a new and theoretical useful approach.

In order to effectively and precisely define the gestures linked to a specific reduction sequence, for example that of the handaxes shaping, a very large number of variables should be taken into consideration (morphology and quality of the raw material, experience of the knapper, context, percussion technique, forecast of use of the handaxe, etc.). But since a simplification, that brings more elements than the classic one [2,3] is needed, the “action grammar approach” can be a good instrument to detect the common element in a shaping reduction sequence. Furthermore, one of the advantages of the proposed methodology lies in the fact that the definition of the different STs (Stone Technology) can be done according to the technological specific characteristics to be studied and to the type of instrument produced.

The deconstruction of knapping sequences could help to detect the degree of complexity of the different steps of the reduction sequences also thanks to the identification of the sub-actions types. The increasing/decreasing of complexity is a very complicate concept in lithic technology. Since at the base of the lithic production there are two basic concepts (angle between the striking platform and the debitage surface - convexity of the debitage/façonnage surface) which are simply declined in an increasingly complex way, it is not easy to define uniquely in what exactly consists the increase in complexity. The approach proposed in the paper “Platforms of Palaeolithic knappers reveal complex linguistic abilities” can help to have new evidences, according to the identification of the required cognitive abilities.

The proposed example of formal grammar still needs to be confirmed on archaeological collections, but it is probable that a practical application will allow to further develop the methodology and possibly to highlight additional possibilities of the approach.

Wood is a widely available and versatile material, so it is not surprising that it has been a key resource throughout human history. However, it is more vulnerable to decomposition than other materials, and its direct use is only rarely recorded in prehistoric sites. Despite this, there are exceptions (e.g., [1-5] [6] and references therein), and indirect evidence of its use has been attested through use-wear analyses, residue analyses (e.g., [7]) and imprints on the ground (e.g., [8]). One interesting finding of note is that the technology required to make, for example, wooden spears was quite complex [9], leading some authors to propose that this type of tool production represented a cognitive leap for Pleistocene hominids [10]. Other researchers, however, have proposed that the production process for wooden tools could have been much easier than is currently thought [11]. Be that as it may, in recent years researchers have begun to approach wood remains systematically, developing analyses of natural and anthropogenic damage, often with the help of experimental reference samples.

In this work, the authors elaborate a comprehensive glossary as a first step towards the understanding of the use of wood for technological purposes in different times and places, as there is still a general gap in the established nomenclature. Thus, this glossary is a synthesis and standardisation of analytical terms for early wood technologies that includes clear definitions and descriptions of traces from stone tool-using cultures, to avoid confusion in ongoing and future studies of wood tools. For this, the authors have carried out a detailed search of the current literature to select appropriate terms associated with additional readings that provide a wide, state-of-the-art description of the field of wood technology.

An interesting point is that the glossary has been organised within a chaîne opératoire framework divided into categories including general terms and natural traces, and then complemented by an appendix of images. It is important to define the natural traces –understanding these as alterations caused by natural processes–because they can mask those modifications produced by other agents affecting both unmodified and modified wood before, during or after its human use.

In short, the work carried out by Milks et al. [6] is an excellent and complete assessment and vital to the technological approach to wooden artifacts from archaeological contexts and establishing a common point for a standardised nomenclature. One of its particular strengths is that the glossary is a preprint that will remain open during the coming years, so that other researchers can continue to make suggestions and refinements to improve the definitions, terms and citations within it.

​​This paper [1] covers an interesting topic in that it presents through ethnography an insight into a traditional method of food production which is gradually declining in use. In addition to preserving traditional knowledge, the ethnographic study of grinding stones has the potential for showing how similar tools may have been used by people in the past, particularly from the same geographic region.

The nature of breaking long bones for obtaining marrow is important in Paleolithic archaeology, due to its widespread, almost universal, character. Provided that hammer-stone percussion marks can be correctly identified using experimental datasets (e.g., [1]), the anatomical location and count of the marks may be taken to reflect recurrent “cultural” traditions in the Paleolithic [2]. Were MP humans breaking bones intuitively or did they abide by a strict “protocol”, and, if the latter, was this protocol optimized for marrow retrieval or geared towards another, less obvious goal?
The new preprint by Vettese and colleagues [3] took a novel approach to this question, by conducting an experiment which involved novice butchers, relying on nothing but their intuition, and recording the way in which they broke marrow-rich bones. Some variability was noted in the “intuitive” patterns; indeed, future studies replicating this experiment and adding more variables such as more experienced butchers and non-bovid bones are warranted. Similarities in the means by which novice butchers break bones was also observed, and especially telling is the strong effect of anatomical features in most bones, except for the femur.

This paper provides a baseline for location analyses of percussion marks. Their dataset may therefore be regarded as a null hypothesis according to which the archaeological data could be tested. If Paleolithic patterns of percussion marks differ from Vettese et al.’s [3] “intuitive” patterns, then the null hypothesis is disproved and one can argue in favor of a learned pattern. The latter can be a result of ”culture”, as Vettese et al. [3] phrase it, in the sense of nonrandom action that draws on transmitted knowledge. Such comparisons bear a great potential for understanding the degree of technological behavior in the Paleolithic by factoring out the “natural” constraints of bone breakage patterns. Vettese et al. [3: fig. 14] started this discourse by comparing their experimental dataset to some Middle and Upper Paleolithic faunas; we are confident that many other studies will follow.

Most archaeological contexts provide objects without organic materials making them quite silent regarding their hafting techniques and use. This is especially true for the polished stone tools that only thanks to a few discoveries in a wet environment, we can obtain some insights regarding their hafting techniques. Use-wear analysis can also be of some support to get a better picture of these artefacts (e.g. Masclans Latorre 2020), whose typology testifies to an important diversity in European Neolithic contexts that sometimes are well-documented from the chaîne opératoire perspective (see De Labriffe and Thirault dir. 2012). 

The study offered by Chris Buckley (2023) constitutes an important contribution to animating these tools. His work relies on the Asia Pacific region, where he gathered data and mapped more than 300 ethnographic hafted stone and shell tools. This database is available on a webpage  https://www.google.com/maps/d/u/0/viewer?mid=1D_sC7VUtQRuRcCgc9rROVU7ghrdiVAg&ll=-2.458804534247277%2C154.35254980859378&z=6, providing a short description and pictures of some of the items, completed by Supplementary data. 

Thanks to this important record of entire objects, the author presents the different possibilities regarding hafting styles, blade orientations and attachment techniques. The combination of these different characteristics led the author to the introduction of a dynamic typology based on the concept of ‘morphospace’. Eight types have been so identified for the Asia Pacific region. 

The geographical distribution of these types is then presented and questioned, bringing also to the forefront some archaeological findings. An emphasis is made on New Guinea island where documentation is important. We can mention the emblematic work of Anne-Marie and Pierre Pétrequin (1993 and 2020) focused on West Papua, providing one of the most consulted books on stone axes by archaeologists. 

The worthy explanations tested to understand this repartition mobilize archaeological or linguistic data to hypothesise a three waves model of innovations in link with agricultural practices. A discussion on the correlation between material culture and language highlights in the background the need for interdisciplinary to deal finely with these interactions and linkages as has been effectively demonstrated elsewhere (Hermann and Walworth 2020).

To conclude, the convergence between European Neolithic and New Guinea polished stone tools is demonstrated here through ‘morphospace’ comparisons. Thanks to this study, the polished stone tools come alive more than any European archaeological context would allow. The population dynamics investigated through these tools are directly relevant to current scientific issues concerning material culture. This example of convergent evolution is therefore an important key to considering this article as a source of inspiration for the archaeological community.
