Dental caries in South African fossil hominins

open access: yesSouth African Journal of Science, 2021
Once considered rare in fossil hominins, caries has recently been reported in several hominin species, requiring a new assessment of this condition during human evolution.

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

open access: yesThe Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

Hominin landscapes and co-evolutionary ecology: accommodating logical incoherence and complexity [PDF]

open access: yes, 2012
Understanding primate (and human) evolutionary environments is a key goal of palaeoanthropology. The most recent contribution to this debate, the ‘tectonic landscape model’ (TLM) is the first to explicitly invoke either the spatial structure of ...

Interpreting sulci on hominin endocasts: Old hypotheses and new findings

open access: yesFrontiers in Human Neuroscience, 2014
Paleoneurologists analyze internal casts (endocasts) of fossilized braincases, which provide information about the size, shape and, to a limited degree, sulcal patterns reproduced from impressions left by the surface of the brain.

Bringing trees back into the human evolutionary story: recent evidence from extant great apes

open access: yesCommunicative & Integrative Biology, 2023
Hypotheses have historically linked the emergence and evolution of defining human characteristics such as bipedal walking to ground-dwelling, envisioning our earliest ancestors as living in treeless savannahs (i.e.

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

open access: yesThe Anatomical Record, EarlyView.
Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

Twin pregnancies and the limits of the energetics of gestation and growth hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract The “Energetics of Gestation and Growth” (EGG) hypothesis proposes that human birth timing and the associated secondary altriciality of human newborns is determined by limits in maternal metabolic capacity. According to this model, labor is triggered when the increasing fetal energy requirements exceed the expectant mother's maximum sustained ...

Evolution of the hominin brain: A review of variations in size and shape

open access: yes, 2015
If we aim to understand the acquisition of human cognitive organization during hominin evolution, two fundamental and complementary lines of evidence must be taken into account: the first is paleoneurological, based on the analyses of brain "endocasts ...

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

open access: yesThe Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Long-term behavioral adaptation of Oldowan toolmakers to resource-constrained environments at 2.3 Ma in the Lower Omo Valley (Ethiopia)

open access: yesScientific Reports, 2023
The long stratigraphic sequence of the Shungura Formation in the Lower Omo Valley documents 3 million years (Ma) of hominin evolution, which, when combined with detailed paleo-depositional environmental data, opens new perspectives for understanding the ...
