Interpreting statistical significance in hominin dimorphism: Power and Type I error rates for resampling tests of univariate and missing-data multivariate size dimorphism estimation methods in the fos…
Using point clouds to investigate the relationship between trabecular bone phenotype and behavior: An example utilizing the human calcaneus
OBJECTIVES: The objective of this study is to demonstrate a new method for analyzing trabecular bone volume fraction and degree of anisotropy in three dimensions. METHODS: We use a combination of automatic mesh registration, point-cloud correspondence registration, and P-value corrected univariate statistical tests to compare bone volume fraction and degree of anisotropy on a point by point basis across the entire calcaneus of two human groups wi…
Combinations of trabecular and cortical bone properties distinguish various loading modalities between athletes and controls
OBJECTIVES: Variation in trabecular and cortical bone properties is often used to infer habitual behavior in the past. However, the structures of both types of bone are rarely considered together and may even contradict each other in functional interpretations. We examine trabecular and cortical bone properties in various athletes and sedentary controls to clarify the associations between combinations of cortical and trabecular bone properties an…
Automated resolution independent method for comparing in vivo and dry trabecular bone
Objectives Variation in human trabecular bone morphology can be linked to habitual behavior, but it is difficult to investigate in vivo due to the radiation required at high resolution. Consequently, functional interpretations of trabecular morphology remain inferential. Here we introduce a method to link low‐ and high‐resolution CT data from dry and fresh bone, enabling bone functional adaptation to be studied in vivo and results compared to the…

Transparency, usability, and reproducibility: Guiding principles for improving comparative databases using primates as examples
Recent decades have seen rapid development of new analytical methods to investigate patterns of interspecific variation. Yet these cutting‐edge statistical analyses often rely on data of questionable origin, varying accuracy, and weak comparability, which seem to have reduced the reproducibility of studies. It is time to improve the transparency of comparative data while also making these improved data more widely available. We, the authors, met …
Does the primate pattern hold up? Testing the functional significance of infraorbital foramen size variation among marsupials
OBJECTIVES: The relative size of the infraorbital foramen (IOF) has been used to infer the ecology of extinct primates for several decades. Primates have relatively smaller IOFs than most other mammals, which may result from the fact that they pre-process and manipulate food with their hands rather than their muzzles. In primates, relative IOF area co-varies with diet, where insectivores and folivores have relatively smaller IOFs than frugivores.…

Sexual Size Dimorphism in Australopithecus: Current Understanding and New Directions
Reassessing manual proportions in Australopithecus afarensis
Previous analyses of hand morphology in Australopithecus afarensis have concluded that this taxon had modern human‐like manual proportions, with relatively long thumbs and short fingers. These conclusions are based on the A.L.333 composite fossil assemblage from Hadar, Ethiopia, and are premised on the ability to assign phalanges to a single individual, and to the correct side and digit. Neither assignment is secure, however, given the taphonomy …
Great ape skeletal collections: Making the most of scarce and irreplaceable resources in the digital age
Information about primate genomes has re‐emphasized the importance of the great apes ( Pan , Gorilla , and Pongo ) as, for most purposes, the appropriate comparators when generating hypotheses about the most recent common ancestor of the hominins and panins, or the most recent common ancestor of the hominin clade. Great ape skeletal collections are thus an important and irreplaceable resource for researchers conducting these types of comparative …
Females are the ecological sex: Sex‐specific body mass ecogeography in wild sifaka populations ( Propithecus spp.)
Previous work in primates has shown that body size often covaries with ecological parameters related to resource or energy availability in the environment. This relationship may differ for males and females as access to resources has greater importance for reproductive success in females. We test the hypotheses that (1) female body mass may be more tightly constrained than male body mass by ecological variables, and (2) female body mass may respo…
A resampling approach and implications for estimating the phalangeal index from unassociated hand bones in fossil primates
Primate fossil assemblages often have metacarpals and phalanges from which functional/behavioral interpretations may be inferred. For example, intrinsic hand proportions can indicate hand function and substrate use. But, estimates of intrinsic hand proportions from unassociated hand elements can be imperfect due to digit misattribution. Although isolated metacarpals can be identified to a specific digit, phalanges are difficult to assign to a spe…
Evaluating the use of pairwise dissimilarity metrics in paleoanthropology
Growth and the development of sexual size dimorphism in lorises and galagos
Three fundamental ontogenetic pathways lead to the development of size differences between males and females. Males and females may grow at the same rate for different durations (bimaturism), grow for the same duration at different rates, or grow at a mix of rate and duration differences. While patterns of growth and the development of adult body size are well established for many haplorhines, the extent to which rate and duration differences aff…

Bioenergetic Constraints on Primate Abundance
Upper limb kinematics and the role of the wrist during stone tool production
Past studies have hypothesized that aspects of hominin upper limb morphology are linked to the ability to produce stone tools. However, we lack the data on upper limb motions needed to evaluate the biomechanical context of stone tool production. This study seeks to better understand the biomechanics of stone tool‐making by investigating upper limb joint kinematics, focusing on the role of the wrist joint, during simple flake production. We test t…

Strong postcranial size dimorphism in Australopithecus afarensis: Results from two new resampling methods for multivariate data sets with missing data
There is considerable debate over the level of size dimorphism and inferred social behavior of Australopithecus afarensis . Most previous studies have analyzed size variation in single variables or multiple variables drawn from single elements. These approaches suffer from small sample sizes, underscoring the need for new techniques that incorporate measurements from multiple unassociated elements, reducing the influence of random sampling on siz…
