Finite element analysis of Neanderthal and early Homo sapiens maxillary central incisor J. Hum. Evol.

Neanderthal anterior teeth are very large and have a distinctive morphology characterized by robust ‘shovel-shaped’ crowns. These features are frequently seen as adaptive responses in dissipating heavy mechanical loads resulting from masticatory and non-masticatory activities. Although the long-standing debate surrounding this hypothesis has played a central role in paleoanthropology, is still unclear

Evidence for the smallest fossil Pongo in southern China J. Hum. Evol. (IF 3.2) Pub Date : 2024-02-27 Hua Liang, Terry Harrison, Qingfeng Shao, Jean-Jacques Bahain, Jinyou Mo, Yuexing Feng, Wei Liao, Wei Wang
The rarity of fossils with precise absolute dating from the Middle Pleistocene hampers our understanding of the taxonomy and spatiotemporal distribution of Quaternary orangutans in southern China. Here, we report a newly discovered sample of 113 isolated teeth of fossil from Zhongshan Cave in the Bubing Basin, Guangxi, southern China. We describe the specimens from Zhongshan Cave and compare them metrically

Relative leg-to-arm skeletal strength proportions in orangutans by species and sex J. Hum. Evol. (IF 3.2) Pub Date : 2024-02-26 Alexandra E. Kralick, Babette S. Zemel, Clara Nolan, Phillip Lin, Matthew W. Tocheri
Among extant great apes, orangutans climb most frequently. However, Bornean orangutans () exhibit higher frequencies of terrestrial locomotion than do Sumatran orangutans (). Variation in long bone cross-sectional geometry is known to reflect differential loading of the limbs. Thus, Bornean orangutans should show greater relative leg-to-arm strength than their Sumatran counterparts. Using skeletal

Bipedal locomotion was a major functional change during hominin evolution, yet, our understanding of this gradual and complex process remains strongly debated. Based on fossil discoveries, it is possible to address functional hypotheses related to bipedal anatomy, however, motor control remains intangible with this approach. Using comparative models which occasionally walk bipedally has proved to be

Since the initial discovery of at the site of Kromdraai in 1938, the hypodigm of this species has been expanded by subsequent work at the localities of Swartkrans and Drimolen, with a few fossils also known from Cooper's D, Gondolin and Sterkfontein Member 5.

Effect of binocular visual cue availability on fruit and insect grasping performance in two cheirogaleids: Implications for primate origins hypotheses J. Hum. Evol. (IF 3.2) Pub Date : 2024-02-06 A, d, d, i, s, o, n, , D, ., , K, e, m, p
Forward-facing eyes with parallel optic axes, which provide a wide field of binocular vision and precise depth perception, are among the diagnostic features of crown primates; however, the adaptive significance of this feature remains contentious. Two of the most prominent primate-origins hypotheses propose that either foraging for fruit or nocturnal predation on insects created selective pressures

Distinguishing agents of bone modification at paleoanthropological sites is an important means of understanding early hominin evolution. Fracture pattern analysis is used to help determine site formation processes, including whether hominins were hunting or scavenging for animal food resources. Determination of how these behaviors manifested in ancient human sites has major implications for our biological

A frequent source of debate in paleoanthropology concerns the taxonomic unity of fossil assemblages, with many hominin samples exhibiting elevated levels of variation that can be interpreted as indicating the presence of multiple species. By contrast, the large assemblage of hominin fossils from the Rising Star cave system, assigned to Homo naledi, exhibits a remarkably low degree of variation for

Cercopithecins differ from papionins in lacking a M3 hypoconulid. Although this loss may be related to dietary differences, the functional and developmental ramifications of hypoconulid loss are currently unclear. The following makes use of dental topographic analysis to quantify shape variation in a sample of cercopithecin M3s, as well as in a sample of Macaca, which has a hypoconulid. To help understand

Recent Plio-Pleistocene hominin findings have revealed the complexity of human evolutionary history and the difficulties involved in its interpretation.

The genus Macaca includes medium- to large-bodied monkeys and represents one of the most diverse primate genera, also having a very large geographic range. Nowadays, wild macaque populations are found in Asia and Africa, inhabiting a wide array of habitats. Fossil macaques were also present in Europe from the Late Miocene until the Late Pleistocene. Macaques are considered ecologically flexible monkeys

Ekgmowechashala is a poorly documented but very distinctive primate known only from the late early Oligocene (early Arikareean) of western North America. Because of its highly autapomorphous dentition and spatiotemporal isolation, the phylogenetic and biogeographic affinities of Ekgmowechashala have long been debated.

Sexual dimorphism of the nervous system has been reported for a wide range of vertebrates.

Understanding the phylogenetic relationships among hominins and other hominoid species is critical to the study of human origins.

Previous studies of hominin phylogenetics have used Papio and Colobus as outgroups in their analyses; however, these extant monkeys possess many derived traits that may confound

Patterns of so-called modern human behavior are increasingly well documented in an abundance of Middle Stone Age archaeological sites across southern Africa.

Paranthropus boisei is well represented in the eastern African fossil record by craniodental remains, but very few postcranial fossils can be securely attributed to this taxon. For this reason, KNM-ER 1500 from East Turkana, Kenya, is especially important.

The macroevolutionary dynamics of activity pattern in mammals: Primates in context J. Hum. Evol. (IF 3.2) Pub Date : 2023-09-21 Jeremiah E. Scott
Activity pattern has played a prominent role in discussions of primate evolutionary history.

Morphological traits suggesting powerful jumping abilities are characteristic of early crown primate fossils. Because tree squirrels lack certain ‘primatelike’ grasping features but frequently travel on the narrow terminal branches of trees, they make a viable extant model for an early stage of primate evolution.
