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.

Fossil skulls reveal that blood flow rate to the brain increased faster than brain volume during human evolution [PDF]
Royal Society Open Science, 2016 The evolution of human cognition has been inferred from anthropological discoveries and estimates of brain size from fossil skulls. A more direct measure of cognition would be cerebral metabolic rate, which is proportional to cerebral blood flow rate ...

Cytomegalovirus distribution and evolution in hominines [PDF]
Virus Evolution, 2019 Abstract Herpesviruses are thought to have evolved in very close association with their hosts. This is notably the case for cytomegaloviruses (CMVs; genus Cytomegalovirus) infecting primates, which exhibit a strong signal of co-divergence with their hosts. Some herpesviruses are however known to have crossed species barriers.

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 ...

Hominin cognitive and behavioural complexity in the Pleistocene: assessment through identity, intentionality and visual display [PDF]
, 2011 The Social Brian Hypothesis predicts the cognitive ability of hominin species by utilising estimated brain and group sizes in relation to an ordinal scale of cognitive complexity expressed as orders of intentionality.

Ecology of a widespread large omnivore, Homo sapiens, and its impacts on ecosystem processes
Ecology and Evolution, 2019 Discussions of defaunation and taxon substitution have concentrated on megafaunal herbivores and carnivores, but mainly overlooked the particular ecological importance of megafaunal omnivores. In particular, the Homo spp.

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

Rethinking Phylogeny and Ontogeny in Hominin Brain Evolution [PDF]
, 2012 Theories of hominin and human cognitive evolution have traditionally focused on the phylogeny of the human brain, and on comparisons of human and primate brains in relation to social or ecological variables.
