Identifying factors that influence technological evolution in small-scale societies is important for understanding human evolution. There have been a number of attempts to identify factors that influence the evolution of food-getting technology, but little work has examined the factors that affect the evolution of other technologies. Here, we focus on variation in technological richness (total number of material items and techniques) among recent hunter–gatherers from western North America and…

Mobility and Cultural Diversity in Central-Place Foragers: Implications for the Emergence of Modern Human Behavior
Although anthropologists have long recognized the importance of mobility to hunter-gatherers, much work remains to be done on the issue of how mobility impacts levels of cultural diversity in
Population structure drives cultural diversity in finite populations: A hypothesis for localized community patterns on Rapa Nui (Easter Island, Chile)
TLDR
Using Rapa Nui (Easter Island, Chile) as an example, a model-based hypothesis is developed for how the structural constraints of communities living in small, isolated populations had dramatic effects and likely led to preventing the loss of cultural information in both community patterning and technology.
Effective Population Size and the Effects of Demography on Cultural Diversity and Technological Complexity
A central tenet of the so-called demographic hypothesis is that larger populations ought to be associated with more diverse and complex toolkits. Recent empirical tests of this expectation have
A multilevel analytical framework for studying cultural evolution in prehistoric hunter–gatherer societies
TLDR
A multilevel analytical framework is proposed that considers finer aspects of the complex social structure in which regional groups of prehistoric hunter–gatherers were embedded and will contribute to improving the understanding of social interaction patterns, as well as the contexts in which cultural changes occur.
Partial connectivity increases cultural accumulation within groups
TLDR
An experiment demonstrating that partially connected groups produce more diverse and complex cultural traits than fully connected groups is presented, which suggests that changes in patterns of interaction between human groups may have created propitious conditions for the emergence of complex cultural repertoires in the authors' evolutionary past.
Hunter-Gatherer Mobility and Versatility: A Consideration of Long-Term Lithic Supply in the Midwest
Hunter-gatherer societies held sway in midwestern North America for at least 11,000 years. Those at the end of this period were more complex and less mobile, and they supported larger populations
Divide and conquer: intermediate levels of population fragmentation maximize cultural accumulation
TLDR
It is shown that, for a given population size, there exists an intermediate level of population fragmentation that maximizes the rate of cumulative cultural evolution, and population structure needs to be taken into account when investigating the relationship between demography and cumulative culture.
Revisiting the effect of population size on cumulative cultural evolution
Henrich (2004) argued that larger populations can better maintain complex technologies because they contain more highly skilled people whom others can imitate. His original model, however, did not
Identifying early modern human ecological niche expansions and associated cultural dynamics in the South African Middle Stone Age
TLDR
It is argued that this niche shift was made possible by the development of a flexible technological system, reliant on composite tools and cultural transmission strategies based more on “product copying” rather than “process copying,” which counter the one niche/one human taxon equation.

Causes of toolkit variation among hunter-gatherers: a test of four competing hypotheses
Variation in subsistence-related material culture is an important aspect of the archaeological and ethnographic records, but the factors that are responsible for it remain unclear. Here, we examine
Population size predicts technological complexity in Oceania
  • M. Kline, R. Boyd
  • Biology
    Proceedings of the Royal Society B: Biological Sciences
  • 2010
TLDR
It is shown that in Oceania, around the time of early European contact, islands with small populations had less complicated marine foraging technology, suggesting that demography plays an important role in generating cumulative cultural adaptation.
What drives the evolution of hunter–gatherer subsistence technology? A reanalysis of the risk hypothesis with data from the Pacific Northwest
TLDR
The analyses suggest that the plateau was a more risky environment than the northwest coast, which seems to reflect an important but hitherto unappreciated feature of the relationship between risk and toolkit structure, namely that the impact of risk is dependent on the scale of the risk differences among populations.
Population Size and Cultural Evolution in Nonindustrial Food-Producing Societies
TLDR
This study investigates whether the subsistence toolkits of small-scale food-producers are influenced by population size in the manner the hypothesis predicts and suggests that population size influences cultural evolution in nonindustrial food-producing populations.
Modeling Effects of Local Extinctions on Culture Change and Diversity in the Paleolithic
TLDR
This study investigates whether the appearance of stability in early Paleolithic technologies could result from frequent extinctions of local subpopulations within a persistent metapopulation, and investigates the effects of demographic factors on rates of culture change and diversification.
An Interaction Model for Resource Implement Complexity Based on Risk and Number of Annual Moves
  • D. Read
  • Computer Science
    American Antiquity
  • 2008
TLDR
A regression model based on interaction between growing season as a proxy measure for risk and number of yearly moves fits data on the complexity of implements for 20 hunter-gatherer groups, and leads to a division of hunter- Gatherer groups into two subgroups that correspond to collector vs. forager strategies for procuring resources.

A combination of archeological and ethnohistorical evidence indicates that, over an approximately 8,000-year period, from the beginning of the Holocene until European explorers began arriving in the
Late Pleistocene Demography and the Appearance of Modern Human Behavior
TLDR
A population model shows that demography is a major determinant in the maintenance of cultural complexity and that variation in regional subpopulation density and/or migratory activity results in spatial structuring of cultural skill accumulation.
Demography and Cultural Innovation: a Model and its Implications for the Emergence of Modern Human Culture
  • S. Shennan
  • Biology
    Cambridge Archaeological Journal
  • 2001
TLDR
It is suggested that the model has major implications for the origins of modern human culture in the last 50,000 years, which may be seen not as the result of genetic mutations leading to improved cognitive capacities of individuals, but as a population consequence of the demographic growth and increased contact range which are evident at this time.
Variable Cultural Acquisition Costs Constrain Cumulative Cultural Evolution
TLDR
This paper presents macroscopic and individual-based models of cumulative cultural evolution that explore the consequences of this assumption of variable cultural acquisition costs, showing that making acquisition costs vary with cultural complexity causes the latter to reach an upper limit above which no further innovation can occur.
