TL;DR: In this paper , the essential role of carbohydrates in the human reproduction cycle and the brain and the effects on physical performance is discussed. But although individual and short-term survival is possible on a relatively low-carbohydrate diet, populations are unlikely to have thrived and reproduced without plants and the carbohydrates they provide.

TL;DR: In this article , a set of dental and postcranial elements were found at Callao Cave (Northern Luzon, Philippines) and dated to at least 50-67 ka.

TL;DR: In this paper , an updated hypothesis of phylogenetic relationships for Middle-Late Miocene fossil apes, focusing on those taxa typically considered to be great apes, was provided, which can be used to gain a better understanding of important morphological transitions that took place during hominid evolution.

TL;DR: A comparative mammalian zoogeographic analysis with the aim of revealing the extent to which the Dmanisi Early Pleistocene large mammal assemblage resembles, at the genus level, African, Arabian, and Eurasian localities of similar age was conducted by as mentioned in this paper .

TL;DR: In this paper , the authors investigated the circumstances of accidental flake production as a byproduct of percussive foraging in wild capuchin monkeys (Sapajus libidinosus) from Brazil.

TL;DR: In this paper , the authors compare the lower/hindlimb joint mechanics of human and bipedal chimpanzees walking over a full stride and test whether: 1) the estimated limb joint work and power during the stance phase, especially the single-support period, is lower in humans than bipedsal chimpanzees, 2) the limb joint strength required for limb swing is lower and 3) the total mechanical power during walking, accounting for the storage and release of passive elastic strain energy in humans, is higher than in bipeds.

TL;DR: In this article , the authors reported the first reconstruction of a fairly complete posterior cranium, Xujiayao 6 (XJY 6), confidently dated to ∼200-160 ka, which facilitated an assessment of its overall cranial size.

TL;DR: In this article , the authors explored the paleohabitats of Woranso-Mille through its faunal community ecological structure and taxonomic composition using correspondence analysis and Forbes modified similarity index, and found that it was a mosaic of different habitat types, with riparian woodland and floodplain grassland along rivers draining into a lake, along with less mesic habitats such as woodland, grassland, and shrubland.

TL;DR: In this paper , the authors used a permutational hierarchical method called boostrapping cluster analysis based on taxonomic absence/presence matrices (at both generic and specific level) and carried out Mantels tests assessing magnitude of time, space, ecology, and taxonomy as source of difference between guilds.

TL;DR: In this paper , the authors used the WorldClim v. 2.1 climate database to reconstruct the climate at Dmanisi (Georgia) during human occupation of the site.

TL;DR: In this article , the cochlear morphology of two Indonesian H. erectus individuals (Sangiran 2 and 4) was compared with a sample of australopiths, Middle to Late Pleistocene humans, and extant humans by means of linear measurements and both principal components and canonical variates analyses performed on shape ratios.

TL;DR: In this paper , the authors examine evidence for the seasonal scheduling of resource procurement and technological investment in the Oldowan, starting with an evaluation of the seasonal signature of underground storage organs, freshwater resources, and terrestrial animal resources in extant primates and modern human hunter-gatherer populations.

TL;DR: A case study of the D2280 adult cranium, which presents four oval-shaped lesions on the frontal, left parietal, and occipital bones is presented in this article .

TL;DR: In this paper , a new chronological framework is provided for the Orgnac 3 sequence based on results of dating methods applied to various types of geological materials, such as heated flints and herbivore teeth, are analyzed in the present work by trapped charge dating methods such as thermoluminescence and electron spin resonance combined with uranium series (ESR/U-series).

TL;DR: In this paper , the results of a multi-isotope, multitissue study of ungulate remains from the Middle Paleolithic site of Abri du Maras, southern France, providing new insights into the living landscapes of the Rhône Valley during MIS 3 (level 4.2 = 55 ± 2 to 42 ± 3 ka; level 4.1 = 46 ± 3 to 40 ± 3), were presented.

TL;DR: For example, this article investigated the party size of a recently habituated community living in the savanna-woodland mosaic landscape of the Issa Valley, western Tanzania, by following chimpanzees daily and recording party size every hour, finding that party size at Issa 1) followed seasonal fluctuations in food availability, 2) increased in the presence of swollen females, and 3) was higher in open vegetation.

TL;DR: In this article , small mammals (insectivores, rodents, and lagomorphs) from Dmanisi are reviewed for the first time and used as a tool for paleoenvironmental proxies.

TL;DR: The authors reviewed the postcranial remains attributed to African hominin taxa from the Late Miocene to the Middle and Late Pleistocene and place these assignations into categories of reliability.

TL;DR: In this paper , the authors compare the anterior vault shapes of two Early Pleistocene (1.55 and 1.26 Ma) fossils from Gona, Ethiopia, and assess whether morphological differences between them reflect temporal evolution or sexual variation.

TL;DR: In this paper , the authors report a case that demonstrates how unexpected intrusion of recent human remains into older stratigraphic levels could occur in cave sediments and further highlights the need of direct dating and taphonomic assessment before accepting either model.

TL;DR: In this paper , the authors investigated the occurrence and morphology of the calcar femorale in an adult sample of extant humans, Pan troglodytes, Gorilla gorilla, Pongo sp., and Papio ursinus.

TL;DR: In this article , the authors used microcomputed tomography to determine cross-sectional diaphyseal properties, with an emphasis on midshaft anteroposterior to mediolateral bending rigidity (Ix/Iy), which has been shown to relate to both body shape and activity level in modern humans.

TL;DR: In this paper , the authors analyzed a large database on energy expenditure in adult humans (1494 males and 3108 females) to investigate whether humans have evolved sex differences in the degree of interindividual variation in energy expenditure and found that, even when statistically comparing males and females of the same age, height, and body composition, there is much more variation in total, activity, and basal energy expenditure among males.

TL;DR: In this article , the results of dating, material culture, and the archaeological context of finds from the Balanica Cave Complex in Sićevo (Serbia) were used to date the sequence.

TL;DR: The early Middle Pleistocene human material from Boxgrove (West Sussex, UK) consists of a partial left tibia and two lower incisors from a separate adult individual as mentioned in this paper .
