“…The behavior determined by designs (structures) movements quantified by these performances can also be determined as a “moving morphology” [ 53 ]. Actually, it is usual to measure these performances based on kinematic data (e.g., velocity, acceleration) extracted from the behavioral sequences (at various speeds) combined (or not) with many means of recording MPs such as electromyography ( EMG) [ 10 ], dynamic imaging techniques (e.g., X-ray Reconstruction of Moving Morphology (XROMM) and fluoromicrometry [ 53 ], and finite element analysis (FEA) [ 54 ]).…”

Postures and movements have been one of the major modes of human expression for understanding and depicting organisms in their environment. In ethology, behavioral sequence analysis is a relevant method to describe animal behavior and to answer Tinbergen’s four questions testing the causes of development, mechanism, adaptation, and evolution of behaviors. In functional morphology (and in biomechanics), the analysis of behavioral sequences establishes the motor pattern and opens the discussion on the links between “form” and “function”. We propose here the concept of neuroethological morphology in order to build a holistic framework for understanding animal behavior. This concept integrates ethology with functional morphology, and physics. Over the past hundred years, parallel developments in both disciplines have been rooted in the study of the sequential organization of animal behavior. This concept allows for testing genetic, epigenetic, and evo-devo predictions of phenotypic traits between structures, performances, behavior, and fitness in response to environmental constraints. Based on a review of the literature, we illustrate this concept with two behavioral cases: (i) capture behavior in squamates, and (ii) the ritualistic throat display in lizards.

“…In palaeontology, the bulk of inferences bearing on behaviour, ecology and phylogeny are based on relationships between form and function (Witmer, 1995;Ward, 2002;Rayfield, 2019). Generally, these relationships are investigated by applying three distinct approaches: comparative anatomy, experiments and numerical simulations (Hutchinson and Gatesy, 2006;Benton, 2010).…”

“…The simulation approaches most frequently used in palaeontology, Multibody Dynamics Analysis (MDA) and Finite Element Analysis (FEA), arose from the field of engineering (Richmond et al, 2005;Ross, 2005;Bright, 2014;Brassey et al, 2017;Rayfield, 2019;Lautenschlager, 2020). MDA was initially used to address questions of hominin bipedalism (Crompton et al, 1998;Wang et al, 2004) and dinosaur locomotion (Hutchinson, 2004;Hutchinson et al, 2005;Bates et al, 2010).…”

Bulletins et Mémoires de la Société d' Anthropologie de ParisCette note fait suite à une communication présentée lors des 1846 es journées de la Société d'Anthropologie de Paris dans le cadre de la session "Humanité(s) : définition(s), diversités et limites" Abstract -"Multibody Dynamic Analysis" (MDA) and "Finite Element" Analysis (FEA) are commonly used to investigate biomechanical solicitations relative to a movement. These approaches have been also used in palaeontology to bring extinct animals, such as hominins, "back to life". The purpose of this study is to report on the available literature on the use of MDA and FEA in postcranial palaeoanthropology. We briefly introduce the theoretical aspects of modelling and simulation applied to biomechanics. The theoretical basis and fields of application of MDA and FEA are then presented. A synthesis of the literature highlights palaeoanthropological issues, variables derived, findings obtained and methodological limitations to keep in mind. More generally, this study synthesizes a conceptual framework and recommendations for the use of such approaches in form-function relationships in an evolutionary context.

“…Certainly, a more complete post-cranial fossil record of Paralouatta would contribute to our understanding of this issue. In the absence of more fossils, it is also possible to utilize virtual morpho-functional toolkits (i.e., "engineering toolbox"), which are increasingly being used to analyze both living and fossil functional morphology (Rayfield, 2019). Accordingly, the primary goal of the present study is to perform a battery of different computational analyses in order to test the hypothesis that Paralouatta was habitually semiterrestrial.…”

Getting Its Feet on the Ground: Elucidating Paralouatta’s Semi-Terrestriality Using the Virtual Morpho-Functional Toolbox

Currently, there are no living platyrrhine primates inhabiting the main Caribbean islands. Nevertheless, the fossil record of this area has provided outstanding findings of different New World monkeys that were part of a diverse radiation exhibiting remarkably unusual morphologies. Among these, the Cuban genus Paralouatta corresponds to one of the most enigmatic primates ever found in the Greater Antilles. Some researchers have argued that Paralouatta's post-cranium shows evidence of semi-terrestriality, a locomotor adaptation that is unusual, if not unique, in platyrrhine evolutionary history. Whether or not Paralouatta was truly semi-terrestrial remains uncertain, however, due to a lack of more sophisticated functional analyses on its morphology. Using novel virtual morpho-functional techniques on a comparative sample of 3D talar models belonging to diverse primate species representing three substrate preferences, this study aims to further evaluate whether Paralouatta was a semi-terrestrial genus or not. Geometric morphometrics and finite element analysis were used to empirically assess shape and biomechanical performance, respectively, and then several machine-learning (ML) classification algorithms were trained using both morphometric and biomechanical data to elucidate the substrate preference of the fossils. The ML algorithms categorized the Paralouatta specimens as either arboreal or as species commonly active on both ground and in trees. These mixed results are suggestive of some level of semi-terrestriality, thus representing the only known example of this locomotor behavior in platyrrhine evolutionary history.
