Dental caries in South African fossil hominins

South 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.

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

The 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.

Preserving the impossible: conservation of soft-sediment hominin footprint sites and strategies for three-dimensional digital data capture. [PDF]

, 2013
Human footprints provide some of the most publically emotive and tangible evidence of our ancestors. To the scientific community they provide evidence of stature, presence, behaviour and in the case of early hominins potential evidence with respect to ...

Interpreting sulci on hominin endocasts: Old hypotheses and new findings

Frontiers 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

Communicative & 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.

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

The 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 ...

The nature of culture : an eight-grade model for the evolution and expansion of cultural capacities in hominins and other animals [PDF]

, 2015
Tracing the evolution of human culture through time is arguably one of the most controversial and complex scholarly endeavors, and a broad evolutionary analysis of how symbolic, linguistic, and cultural capacities emerged and developed in our species is ...

Earliest Olduvai hominins exploited unstable environments ~ 2 million years ago

Nature Communications, 2021
Oldupai Gorge, Tanzania is a key site for understanding early human evolution. Here, the authors report a multiproxy dataset from the Western basin of Oldupai Gorge dating to 2 million years ago, enabling the in situ comparison of lithic assemblages ...

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

The 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

Reconstructing cranial evolution in an extinct hominin

Proceedings of the Royal Society B: Biological Sciences, 2021
Homo erectusis the first hominin species with a truly cosmopolitan distribution and resembles recent humans in its broad spatial distribution. The microevolutionary events associated with dispersal and local adaptation may have produced similar population structure in both species. Understanding the evolutionary population dynamics ofH.
