A defining feature of the contemporary world is economic growth, and the most frequently cited cause is technological change, especially with respect to energy capture and information processing. This framing masks the potential for economic growth in nonindustrial societies, but there is growing evidence for episodes where the material conditions of life did improve in the preindustrial past. Here, we explore a potential mechanism behind these improvements. We use settlement scaling theory to distinguish agglomeration-driven from technology-driven growth, and then we apply this framework to archaeological evidence from the Pre-Hispanic Northern Rio Grande Pueblos of New Mexico, USA. Results suggest that agglomeration-driven or “Smithian” growth was the dominant factor behind improvements in the material conditions of life over time in this society. We also summarize evidence that this growth took place in the context of a stable regional population, declining levels of inequality, and increasingly inclusive social institutions.

Scale and information-processing thresholds in Holocene social evolution
Abstract Throughout the Holocene, societies developed additional layers of administration and more information-rich instruments for managing and recording transactions and events as they grew in population and territory. Yet, while such increases seem inevitable, they are not. Here we use the Seshat database to investigate the development of hundreds of polities, from multiple continents, over thousands of years. We find that sociopolitical development is dominated first by growth in polity scale, then by improvements in information processing and economic systems, and then by further increases in scale. We thus define a Scale Threshold for societies, beyond which growth in information processing becomes paramount, and an Information Threshold, which once crossed facilitates additional growth in scale. Polities diverge in socio-political features below the Information Threshold, but reconverge beyond it. We suggest an explanation for the evolutionary divergence between Old and New World polities based on phased growth in scale and information processing. We also suggest a mechanism to help explain social collapses with no evident external causes.

We address three basic issues regarding the long-term dynamics of inequality in society. First, we consider the interpretation of residence sizes in socioeconomic terms by comparing statistical patterns extracted from the Global Dynamics of Inequality (GINI) Project database with those from the 21st-century United States. Second, we examine the degree to which the size and productivity of human networks is systematically related to inequality. Finally, we investigate relationships between productivity and productivity growth distributions for patterns of inequality and development across preindustrial societies. We find that across preindustrial societies residence size distributions provide a reasonable proxy for the distribution of productivity (income, a flow of physical and social resources to the group) and a minimum estimator for the distribution of wealth (a stock of such resources accumulated over time); that scale and productivity affect levels of inequality but account for only a small fraction of the observed variance across societies; and that inequality growth is independent of productivity growth, on average and over time. These findings have important implications for efforts to promote more equitable economic development in the present.more » « less

null (Ed.)The ability to predict when societies will replace one social norm for another can have significant implications for welfare, especially when norms are detrimental. A popular theory poses that the pressure to conform to social norms creates tipping thresholds which, once passed, propel societies toward an alternative state. Predicting when societies will reach a tipping threshold, however, has been a major challenge because of the lack of experimental data for evaluating competing models. We present evidence from a large-scale laboratory experiment designed to test the theoretical predictions of a threshold model for social tipping and norm change. In our setting, societal preferences change gradually, forcing individuals to weigh the benefit from deviating from the norm against the cost from not conforming to the behavior of others. We show that the model correctly predicts in 96% of instances when a society will succeed or fail to abandon a detrimental norm. Strikingly, we observe widespread persistence of detrimental norms even when individuals determine the cost for nonconformity themselves as they set the latter too high. Interventions that facilitate a common understanding of the benefits from change help most societies abandon detrimental norms. We also show that instigators of change tend to be more risk tolerant and to dislike conformity more. Our findings demonstrate the value of threshold models for understanding social tipping in a broad range of social settings and for designing policies to promote welfare.more » « less

Abstract Histories generally portray southern Ethiopians as pagans who lacked kings because they rely on the historical accounts of their northern Abyssinian conquerors, who adopted Christianity in the first century AD. Justified by a call to spread Christianity and suffering the threat of famine and disease to his empire, Abyssinian emperor Menelik II (1889–1913) conquered and colonized southern Omotic-speaking polities, who cultivated a drought-resistant crop, enset (Ensete ventricosum). According to most Ethiopian histories, Boreda were one of the southern Omotic societies, who quickly succumbed to conquest, adopted new agricultural technologies, and paid tribute and corvée labor. Boreda identity and history are entwined with farming enset, a relationship that provided food security, structured their historic settlement landscape, and charted their relationship with technology, each other, and outsiders. The authors argue that everyday practices, such as the farming of enset, are spaces within which Indigenous peoples frame and materialize ontological resilience against colonialism, religious conversion, and persecution. Boreda oral traditions, life histories, and daily practices support their efforts to resist settlers and richly inform the archaeology of their historic places, Bayira Deriya.more » « less

Abstract AimUnderstanding and predicting the biological consequences of climate change requires considering the thermal sensitivity of organisms relative to environmental temperatures. One common approach involves ‘thermal safety margins’ (TSMs), which are generally estimated as the temperature differential between the highest temperature an organism can tolerate (critical thermal maximum, CTmax) and the mean or maximum environmental temperature it experiences. Yet, organisms face thermal stress and performance loss at body temperatures below their CTmax,and the steepness of that loss increases with the asymmetry of the thermal performance curve (TPC). LocationGlobal. Time period2015–2019. Major taxa studiedAnts, fish, insects, lizards and phytoplankton. MethodsWe examine variability in TPC asymmetry and the implications for thermal stress for 384 populations from 289 species across taxa and for metrics including ant and lizard locomotion, fish growth, and insect and phytoplankton fitness. ResultsWe find that the thermal optimum (Topt, beyond which performance declines) is more labile than CTmax, inducing interspecific variation in asymmetry. Importantly, the degree of TPC asymmetry increases with Topt. Thus, even though populations with higher Topts in a hot environment might experience above‐optimal body temperatures less often than do populations with lower Topts, they nonetheless experience steeper declines in performance at high body temperatures. Estimates of the annual cumulative decline in performance for temperatures above Toptsuggest that TPC asymmetry alters the onset, rate and severity of performance decrement at high body temperatures. Main conclusionsSpecies with the same TSMs can experience different thermal risk due to differences in TPC asymmetry. Metrics that incorporate additional aspects of TPC shape better capture the thermal risk of climate change than do TSMs.more » « less
