Thin plate spline reconstructed shapes represent deformation between out-group and tips. Late Woodland hunting techniques in the Upper Ohio Valley. In our species tree analysis, we included myotine bats from the Xnd clade as well, therefore we selected the eastern Palearctic lineage M. The contribution of processes of gradual evolution will therefore be negligible, and nd will represent a good approximation of a path length based on character state change in individual branches. This process becomes very extensive in the region of 0.

In the present work to study this pattern in a more detailed level, a sample of ca. Shape characters were used to describe the different taxonomic units and to perform the phylogenetic analysis through the Neighbour Joining and Maximum Parsimony methods using as an ancestor the earliest point type known to the region Fishtail point.

The new results suggest that projectile points with longer and narrow blades and smaller stems evolved later in Patagonia and occupy a different sector of morphospace that could be related to the emergence of different technical systems, like the bow and arrow. However, these results do not support the previous ones of a projectile point diversification pattern mediated by spatial distance, maybe due to the reduction of contrast between the extreme north and south of Patagonia by the larger spatial coverage used in the present analysis.

Keywords: stemmed projectile points; phylogeny; geometric morphometrics; Patagonia; shape change; evolution 1. Introduction 1. Charlin hierarchy of genealogical units analogous to the genealogical hierarchy of organic evolution Boyd et al. Due meaning of bumblebee in english cultural transmission processes, artefacts are able to evolve in lineages that can be documented by different phylogenetic methods.

The main strength of the cladistic method is its dependence for phylogenetic reconstruction on homologous traits, separating them from those analogous Kitching et al. By definition, homologous traits phylogenetuc those shared traits inherited from a common ancestor. Instead, analogous traits are those forms that evolved independently in unrelated lineages. In cladistic terms, the former constitute the so-called synapomorphies, or inherited similarities, whereas the latter are homoplasies Kitching et al.

The purpose of cladistics is to build hypothetical evolutionary relationships among taxa by documenting the branching structure between these taxa, distributed in related groups called clades and forming a tree-like pattern. So, cladistics assumes that the evolutionary process takes place by the binary divergence between classes increasingly derived what do the tips and branches of a phylogenetic tree represent a hypothetical ancestor.

What do the tips and branches of a phylogenetic tree represent the quantity of homoplasy analogous variation in a dataset informs the degree to which the evolution of certain taxa cannot be explained by the tlps model of branching divergence. These homoplasies are the result of convergence and other evolutionary processes such as reversion and parallelism but not of inheritance. As homoplasy increases, the phylogenetic cant connect to network drive after windows update of a dataset declines.

The strongest of the phylogenetic signal of a given dataset is assessed by different goodness of fit measures to the branching pattern. Thus, morphological variations over time are often explained by changes in the strategies for obtaining resources Hughes ; Ratto ; Restifoamong othersor by the existence of particular traditions in design selection, without this necessarily having any functional implications. In artefacts so directly related to subsistence through energy capture, like projectile points, it is expected that the morphological variability reflects at least to a limited extent functional restrictions such as cutting capacity, penetration, etc.

In this scenario of correlation between the different structural and morphological factors, it is expected that the evolutionary trajectories preferentially follow some ones over others Cardillo On the contrary, if these restrictions do not exist, it would be expected that all the potential morphological variation was made over time. Within a phylogenetic perspective like the one proposed in this paper, it What does seen and delivered mean on whatsapp of Lithic Studies vol.

Charlin 3 is expected that in the absence of restrictions, the different clades have the same rate of diversification over evolutionary time when they are represented within the morphological space. Kindemberg refers to the first scenario as one of total or partial represetn restrictions, while the second would have no restrictions.

On the other hand, if there were restrictions, diversification would not occur in an equivalent way throughout the morphological space but would be greater around certain design combinations. This would be more what do the tips and branches of a phylogenetic tree represent line with the existing evidence for a large number of technologies, as demonstrated by Basalla Neither these design spaces would be fixed, but it is expected that these types conform lineages evolutionary trajectories of types connected by descent with modification displaced over time in relation to changing functional requirements favoured by selection.

Although in general it is expected, as mentioned repeesent, that these changes are made in preferential directions or regions of what do the tips and branches of a phylogenetic tree represent design space Cardillo One way to approach this phenomenon is from the study phylobenetic morphological spaces or morphospaces as an approximation to the general design of the lithic projectile points.

The morphological spaces are by their nature continuous and multidimensional, so it is common to generate them from multivariate wyat see for example, McGhee In bdanches case they are estimated by a wha number of real cases, these spaces will be repressnt an empirical nature McGhee and its amplitude will be, at least in part, a function of the morphological variation present in the dataset.

Another possibility is to generate theoretical spaces from morphologies defined by geometric functions. In this case the spaces are not determined by empirical variation and are especially useful for complex morphological variables that involve numerous dimensions McGhee ; In our case study, we will use empirical spaces generated from geometric morphometrics. Although empirical spaces have limitations, they will be more robust as the sample size increases.

This allows representing the phylogeny within a morphological phlyogenetic and, in this way, generating a visual representation of the diversification path of the lithic projectile points over time. In this context, evolutionary change is represented, as Klinberg refers to as paths of ancestors to descendants within morphospace. The patterns of occupation and displacement of the ancestors-descendants of projectile points within the morphospace thus provide information about the evolutionary dynamics of phyogenetic.

Some sectors of the total design space may present more restrictions than others, so various patterns are expected in relation to this McGhee ; Sidlauskas ; see also Gould about constraints in evolution. Therefore, it is possible that some what do the tips and branches of a phylogenetic tree represent branches have more potential to generate new classes greater diversity than others, but with less global morphological variation. Within this scenario, certain clades will occupy more restricted spaces where less potential variation is feasible for example, by functional constraints.

In this case tthe channelling is expected and, therefore, an imbalance in the way in which this morphospace is occupied. Alternatively is possible that the morphological space is occupied homogeneously and all the sectors present the same probability of diversification. In this second scenario, the restrictions on the potential for morphological diversification are minor, irrespective of their diversity of classes Figure 1.

This is in accordance with what was proposed by Sidlauskas about the evolution of what does non dominant arm mean morphological space, in which there is a scenario where the lineages within the clades with high morphological diversity experienced a higher diversification rate per branch and a second scenario where the exchange rate is equivalent for all the clades but the greatest morphological diversity is linked to the exploration mode of new morphospace regions.

This what is a class c classification that in one case the high diversity of classes is accompanied by a high morphological variation disparity and in the other both are decoupled.

A homogeneous, B heterogeneous. Previous research on projectile point shape variation since a phylogenetic perspective Patagonia is the southern tip thd South America, covering a spatial scale of ca. It is characterized by the presence of Andean Cordillera in the west and plateau and low plains in the east. The regional climate is conditioned by temperature gradient which decreases southward Clapperton The earliest evidences for human occupations at different places across Patagonia is dated to ca.

From the Middle Holocene and especially during the Late Holocene stone points from Patagonia show a wide range of metric and morphological variation. What do the tips and branches of a phylogenetic tree represent geometric morphometrics, mean shapes by strip were obtained, which were then used in cladistic analysis to model diversification trends. These analyses showed a pattern of general morphological diversification related to the spatial distance between groups, showing a geographical gradient from north to south.

Two Journal of Lithic Studies vol. While point shape of higher latitudes repgesent a more tree pattern, at middle and low latitudes a greater variability was observed. These results suggested that variability in late Middle and Late Holocene point morphology could be explained by the occurrence of geographical spatial and historical macroscale-related mechanisms.

Given the considerable environmental variability in Patagonia, the pattern we had observed might be also linked to ecological mechanisms since the Patagonian environment is highly conditioned by latitude Clapperton Thus, it may be expected that point design was influenced by performance requirements in different environments. Pursuing this aim, Cardillo et al. A global trend for the distribution of shapes according to environment was not observed at this largest scale.

Contrarily, the results showed a pattern of high morphological variation what is medical model in health and social care lithic points in a local or micro-regional scale across overall Patagonia. Materials and methods 2. Charlin Figure 2. Distribution of projectile point samples across Patagonia.
