Women’s subsistence strategies predict fertility across cultures, but context matters (2024)
Journal Article
Page, A. E., Ringen, E. J., Koster, J., Borgerhoff Mulder, M., Kramer, K., Shenk, M. K., …Sear, R. (2024). Women’s subsistence strategies predict fertility across cultures, but context matters. Proceedings of the National Academy of Sciences, 121(9), Article e2318181121. https://doi.org/10.1073/pnas.2318181121

While it is commonly assumed that farmers have higher, and foragers lower, fertility compared to populations practicing other forms of subsistence, robust supportive evidence is lacking. We tested whether subsistence activities—incorporating market i... Read More about Women’s subsistence strategies predict fertility across cultures, but context matters.

Child and adolescent foraging: New directions in evolutionary research. (2024)
Journal Article
Pretelli, I., Crittenden, A. N., Dounias, E., Friant, S., Koster, J., Kramer, K. L., …Lew-Levy, S. (2024). Child and adolescent foraging: New directions in evolutionary research. Evolutionary Anthropology, Article e22020. https://doi.org/10.1002/evan.22020

Young children and adolescents in subsistence societies forage for a wide range of resources. They often target child-specific foods, they can be very successful foragers, and they share their produce widely within and outside of their nuclear family...

A dataset of energetic value estimates of wild and domesticated food items consumed by Congolese BaYaka foragers (2023)
Journal Article
Benoit, L., Lew-Levy, S., Ouamba, Y. R., & Crittenden, A. N. (in press). A dataset of energetic value estimates of wild and domesticated food items consumed by Congolese BaYaka foragers. Journal of Ecological Anthropology, https://doi.org/10.6084/M9.FIGSHARE.19453514.V1

We present a dataset that systematically estimates the energetic value of wild and domesticated food resources collected and consumed by Congolese BaYaka foragers. This dataset is unique in that it accounts for everyday practices of food processing a...

Quantifying quality: The impact of measures of school quality on children's academic achievement across diverse societies (2023)
Journal Article
Rawlings, B. S., Davis, H. E., Anum, A., Burger, O., Chen, L., Morales, J. C. C., …Legare, C. H. (2023). Quantifying quality: The impact of measures of school quality on children's academic achievement across diverse societies. Developmental Science, e13434. https://doi.org/10.1111/desc.13434

Recent decades have seen a rapid acceleration in global participation in formal education, due to worldwide initiatives aimed to provide school access to all children. Research in high income countries has shown that school quality indicators have a...

Reproductive inequality in humans and other mammals (2023)

Intergroup Cooperation in Shotgun Hunting Among BaYaka Foragers and Yambe Farmers from the Republic of the Congo (2023)
Journal Article
Kandza, V. H., Jang, H., Ntamboudila, F. K., Lew-Levy, S., & Boyette, A. H. (2023). Intergroup Cooperation in Shotgun Hunting Among BaYaka Foragers and Yambe Farmers from the Republic of the Congo. Human Nature, 34(2), 153-176. https://doi.org/10.1007/s12110-023-09448-0

Whereas many evolutionary models emphasize within-group cooperation or between-group competition in explaining human large-scale cooperation, recent work highlights a critical role for intergroup cooperation in human adaptation. Here we investigate i... Read More about Intergroup Cooperation in Shotgun Hunting Among BaYaka Foragers and Yambe Farmers from the Republic of the Congo.

Peer learning and cultural evolution (2023)
Journal Article
Lew-Levy, S., Bos, W. V. D., Corriveau, K. H., Dutra, N. B., Dutra, N., Flynn, E. G., …Wood, L. (2023). Peer learning and cultural evolution. Child Development Perspectives, 17, 97-105. https://doi.org/10.1111/cdep.12482

In this article, we integrate cultural evolutionary theory with empirical research from developmental psychology, cultural anthropology, and primatology to explore the role of peer learning in the development of complex instrumental skills and behavi...

Associations between men's reputations for fathering and their reproductive success among BaYaka foragers in the Congo Basin (2023)
Journal Article
Boyette, A. H., Lew-Levy, S., Valchy, M., & Gettler, L. T. (2023). Associations between men's reputations for fathering and their reproductive success among BaYaka foragers in the Congo Basin. Evolution and Human Behavior, 44(2), 110-119. https://doi.org/10.1016/j.evolhumbehav.2023.02.005

It is generally recognized that paternal care is a facultative feature of human cooperative caregiving that helps underpin our evolved life history strategy. Yet, little direct evidence links variation in men's fathering to fitness outcomes. Research...
