Children adjust behavior in novel social environments to reflect local cooperative norms inferred from brief exposure
Published: 2024-03-29
Subjects: Anthropology, Social and Behavioral Sciences
Stark intergroup variation in prosocial behavior, as elicited with economic experiments, is evident even though humans are highly mobile. Conformity to local norms has been posited to play an integral role in the maintenance of this variation. Experiments suggest that adults indeed rapidly infer pro- and antisocial norms in a new or changed social environment and adjust their behavior to reflect [...]
Foraging Efficiency and the Importance of Knowledge in Pemba, Tanzania: Implications for Childhood Evolution.
Published: 2022-09-12
Subjects: Anthropology, Behavior and Ethology, Biological and Physical Anthropology, Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences
Childhood is a period of life unique to humans. Childhood may have evolved through the need to acquire knowledge and subsistence skills. In an attempt to evaluate the importance of learning for the evolution of childhood, previous research examined the increase with age of returns to foraging across various resources. Any increase could be due to increases in knowledge or other factors such as [...]
Millet, Rice, and Isolation: Origins and Persistence of the Worlds Most Enduring Mega-State
Published: 2022-06-05
Subjects: Anthropology, Archaeological Anthropology, Asian Studies, Comparative Politics, Economic History, Economics, Geography, Growth and Development, Human Geography, International and Area Studies, International Relations, Models and Methods, Nature and Society Relations, Other Anthropology, Other Economics, Other Political Science, Political Economy, Political Science, Regional Economics, Social and Behavioral Sciences, Social and Cultural Anthropology
We propose and test empirically a theory describing the endogenous formation and persistence of mega-states, using China as an example. We suggest that the relative timing of the emergence of agricultural societies, and their distance from each other, set off a race between their autochthonous state-building projects, which determines their extent and persistence. Using a novel dataset describing [...]
The Evolution of Peace

Subjects: Anthropology, Behavior and Ethology, Biological and Physical Anthropology, Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences, Social and Cultural Anthropology
While some species have affiliative and even cooperative interactions between individuals of different social groups, humans are alone in having durable, positive-sum, interdependent relationships across unrelated social groups. Our capacity to have harmonious relationships that cross group boundaries is an important aspect of our species’ success, allowing for the exchange of ideas, materials, [...]
The Shadow of the Neolithic Revolution on Life Expectancy: A Double-Edged Sword
Published: 2022-03-01
Subjects: Analytical, Diagnostic and Therapeutic Techniques and Equipment, Anthropology, Biological and Physical Anthropology, Congenital, Hereditary, and Neonatal Diseases and Abnormalities, Diseases, Economic History, Economics, Endocrine System Diseases, Growth and Development, Health Economics, Immune System Diseases, Labor Economics, Medicine and Health Sciences, Other Economics, Public Health, Regional Economics, Social and Behavioral Sciences
This research explores the persistent effect of the Neolithic Revolution on the evolution of life expectancy in the course of human history. It advances the hypothesis and establishes empirically that the onset of the Neolithic Revolution and the associated rise in infectious diseases triggered a process of adaptation reducing mortality from infectious diseases while increasing the propensity for [...]
Female bone physiology resilience in a past Polynesian Outlier community

Remodelling is a fundamental biological process involved in the maintenance of bone physiology and function. We know that a range of health and lifestyle factors can impact this process in living and past societies, but there is a notable gap in bone remodelling data for populations from the Pacific Islands. We conducted the first examination of femoral cortical histology in 69 individuals from [...]
The Invention of Fistfighting
Published: 2021-10-21
Subjects: Anthropology, Biological and Physical Anthropology, Social and Behavioral Sciences
It has been hypothesized that key aspects of human male upper limb and facial morphology evolved through selective pressures related to fistfighting. Based on the primatological, archaeological, and ethnographic evidence, I argue these proposals are misguided. An important trend during recent hominin evolution was a decline in upper body strength and facial robusticity, coinciding in part with [...]

On May 16, 2020, the Center for Academic Research and Training in Anthropogeny organized the symposium “Impact of Infectious Disease on Humans and Our Origins”. The symposium aimed to gather experts on infectious diseases in one place and discuss the interrelationship between different pathogens and humans in an evolutionary context. The talks discussed topics including SARS-CoV-2, dengue and [...]
Large-scale cooperation in small-scale foraging societies
Published: 2021-05-18
Subjects: Anthropology, Biological and Physical Anthropology, Social and Behavioral Sciences
We present evidence that people in small-scale, mobile hunter-gatherer societies cooperated in large numbers to produce collective goods. Foragers engaged in large-scale communal hunts, constructed shared capital facilities; they made shared investments in improving the local environment; and they participated in warfare, alliance, and trade. Large-scale collective action often played a crucial [...]
Implementing network approaches to understand the socioecology of human-wildlife interactions
Published: 2021-05-05
Subjects: Animal Sciences, Anthropology, Behavior and Ethology, Biological and Physical Anthropology, Biology, Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences
Human population expansion into wildlife habitats has increased interest in the behavioral ecology of human-wildlife interactions. To date, however, the socio-ecological factors that determine whether, when or where wild animals take risks by interacting with humans and anthropogenic factors still remains unclear. We adopt a comparative approach to address this gap, using social network analysis [...]
Novel phylogenetic methods reveal that resource-use intensification drives the evolution of “complex” societies
Published: 2021-03-24
Subjects: Anthropology, Other Anthropology, Social and Behavioral Sciences
Explaining the rise of large, sedentary populations, with attendant expansions of socio-political hierarchy and labor specialization (collectively referred to as “societal complexity”), is a central problem for social scientists and historians. Adoption of agriculture has often been invoked to explain the rise of complex societies, but archaeological and ethnographic records contradict simple [...]
Human social organization during the Late Pleistocene: Beyond the nomadic-egalitarian model

Many researchers assume that until 10-12,000 years ago, humans lived in small, mobile, relatively egalitarian bands composed mostly of kin. This “nomadic-egalitarian model” informs evolutionary explanations of behavior and our understanding of how contemporary societies differ from those of our evolutionary past. Here, we synthesize research challenging this model and propose an alternative, the [...]
The origins of human cumulative culture: from the foraging niche to collective intelligence
Published: 2021-02-22
Subjects: Anthropology, Biological and Physical Anthropology, Social and Behavioral Sciences
Various studies have investigated cognitive mechanisms underlying culture in humans and other great apes. However, the adaptive reasons for the evolution of uniquely sophisticated cumulative culture in our species remain unclear. We propose that the cultural capabilities of humans are the evolutionary result of a stepwise transition from the ape-like lifestyle of earlier hominins to the foraging [...]
Püllomen: an ethnoecological perspective of the Mapuche protector spirit insect
Published: 2020-09-17
Subjects: Anthropology, Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Anthropology, Social and Behavioral Sciences
Biodiversity plays an important role in cultural worldviews, influencing myths, stories, and spiritual beliefs of indigenous peoples. This short review explores an ecological phenomenon that may have influenced and contributed to the development of the Mapuche good spirit insect (Püllomen), which represents the spirit of someone who passed away and comes back to the world of the living providing [...]
