The Anatomical Record, EarlyView.Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

Food sharing among Ache hunter-gatherers of Eastern Paraguay [PDF]
, 1988 journal articleEmpirical research on food sharing among hunter-gatherers should provide critical data for evaluating both the possible role of food sharing in hominid evolution and the question of how such behavior could be ...

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

PaleoAnthropology, 2020 For more than 10,000 years between the peak of the Last Glacial Maximum and the beginning of the Holocene, people repeatedly returned to the same spot on the southern edge of Paleolake Hula in the Upper Jordan Valley to fish, hunt, and exploit other ...

The Anatomical Record, EarlyView.Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

Diabetes and Mexicans: Why the Two Are Linked
Preventing Chronic Disease, 2005 Obesity and diabetes were probably rare before the advent of agriculture. Our ancestors, hunters and gatherers for millennia, had varied but unpredictable diets.

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation
The Anatomical Record, EarlyView.Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.

Evolutionary morphology of the haplorhine hamate
The Anatomical Record, EarlyView.Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

The pelvis doesn't walk by itself: Wider pelves reduce the cost of walking over unstable surfaces
The Anatomical Record, EarlyView.Abstract Walking over variable and/or unstable terrain is a key aspect of daily life and was crucial to the evolution of bipedalism. The ability to find gait solutions that maintained stability over uneven terrain for the least increase in metabolic cost was likely a hallmark of locomotor effectiveness in early humans, in particular acting as an ...
