Annual War Deaths in Small-Scale versus State Societies Scale with Population Size Rather than Violence
In The Better Angels of Our Nature: Why Violence Has Declined, psychologist Steven Pinker cites mean ratios of war (battle) deaths suffered annually per 100,000 individuals as evidence for concluding that people who live in states are less violent than those who live or lived in "hunting, gathering, and horticultural societies in which our species spent most of its evolutionary history." Because such ratios are blind to actual population sizes, i…
Nonpathological asymmetry in LB1 ( Homo floresiensis ): A reply to Eckhardt and Henneberg
Genetic and environmental contributions to variation in baboon cranial morphology
The development, function, and integration of morphological characteristics are all hypothesized to influence the utility of traits for phylogenetic reconstruction by affecting the way in which morphological characteristics evolve. We use a baboon model to test the hypotheses about phenotypic and quantitative genetic variation of traits in the cranium that bear on a phenotype's propensity to evolve. We test the hypotheses that: 1) individual trai…
The type specimen (LB1) of Homo floresiensis did not have Laron Syndrome
The type specimen (LB1) of Homo floresiensis has been hypothesized to be a pathological human afflicted with Laron Syndrome (LS), a type of primary growth hormone insensitivity (Hershkovitz et al.: Am J Phys Anthropol 134 [2007] 198–208). Comparing measurements, photographs and three‐dimensional, computed‐tomography reconstructions of LB1 with data and diagnoses from the literature on LS, we critically evaluate numerous skull and postcranial trai…
LB1's virtual endocast, microcephaly, and hominin brain evolution
The Brain of LB1, Homo floresiensis
The brain of Homo floresiensis was assessed by comparing a virtual endocast from the type specimen (LB1) with endocasts from great apes, Homo erectus, Homo sapiens , a human pygmy, a human microcephalic, specimen number Sts 5 ( Australopithecus africanus ), and specimen number WT 17000 ( Paranthropus aethiopicus ). Morphometric, allometric, and shape data indicate that LB1 is not a microcephalic or pygmy. LB1's brain/body size ratio scales like t…
Relationship of squamosal suture to asterion on external skull surfaces versus endocasts of pongids: Implications for Hadar early hominid AL 162‐28
The relationship between the squamosal suture and asterion was quantified in 15 hemispheres of eight chimpanzee endocasts that were aligned in the conventional lateral view (i.e., with frontal pole [FP]–occipital pole [OP] horizontal). Using a three‐dimensional digitizer, x, y, and z coordinates were collected for the highest and lowest points of the squamosal suture, and the most rostral point of the suture approximate to the coronal suture. Our…
Hominid enamel thickness: I. The Krapina Neandertals
Dental x‐rays were taken of isolated and in situ adult molar teeth of the Krapina Neandertal (n = 63) and of recent and contemporary molars (n = 423). The radiographs were digitized at high resolution (1,024 × 1,520 × 8 bits) with a 35 mm solid state scanner. Ratios of enamel cap area to the underlying dentinal‐pulpal area were determined and comparisons were made between average ratios for the Neandertal and contemporary molars. Neandertal molar…
External brain morphology in rhesus macaques (Macaca mulatta)
Endocranial suture closure in rhesus macaques ( Macaca mulatta )
Endocasts from skulls of 330 rhesus monkeys ( Macaca mulatta ) of known age are scored for closure of nine bilateral and three unilateral sutures or segments of sutures. A variety of tests reveals a strong relationship between age and stages of suture closure, although increasingly broad confidence intervals prevent sutures from being very useful for precisely aging older macaques. The order in which endosutures begin to close, as well as that in…
