Journal article - Page, A. E. et al. (2021) Children are important too. Phil Trans. B.

Here, using in-depth observational data on who for cares for 78 Agta children (aged 0-6 years, a foraging population in northern Philippines), we explore whether allomaternal childcare substitutes (and thus decreases) maternal childcare.

Journal article - Myers, S., Page, A. E. and Emmott, E. H., (2021) The differential role of practical and emotional support in infant feeding experience in the UK? Phil Trans. B.

Using survey data collected online from 515 UK mothers with infants aged 0–108 weeks, Cox regression models assessed the relationship between receiving different types of support, support need and breastfeeding duration.

Preprint - Page, A. E., Emmott, E. H., and Myers, S. Testing the buffering hypothesis: breastfeeding problems, cessation and social support.

Here, we test the hypothesis that social support buffers mothers from the negative impact breastfeeding problems have on duration on a sample of 566 UK mothers who completed a retrospective online survey about infant feeding and social support in 2017-2018.

Journal article - Page, A. E. and French, J. C. (2020) Reconstructing prehistoric demography. Evolutionary Anthropology

We provide recommendations about the application of hunter-gatherer data to the study of demographic trends throughout human evolution. We use published demographic data from extant hunter-gatherers to show that it is the diversity seen among extant hunter-gatherers that is most relevant for understanding past hunter-gatherer demography.

Using retrospective data from an online survey of UK mothers of children aged 0–24 months, Cox-Aalen survival models test whether negative subjective environmental experiences negatively correlated with any and exclusive breastfeeding.

Using retrospective data from an UK-based online survey (data collection period December 2017 - February 2018), we carry out a latent class regression (n = 432) to identify “clusters” of postnatal support in our data.

We used high-resolution proximity data from 1,701 child–alloparent dyads to test why alloparents help in the Agta.

July 2019

Journal article - Dyble, M. et al. (2019) Engagement in agricultural work is associated with reduced leisure time among Agta hunter-gatherers. Nature Human Behaviour.

A long-standing hypothesis suggests that the transition from hunting and gathering to agriculture results in people working harder, spending more time engaged in subsistence activities and having less leisure time. Here we test this hypothesis by examining adult time allocation among the Agta.

May 2019

Journal article - Page, A. E. et al. (2019) Why so many Agta boys. Evolutionary Human Sciences

The Agta, a foraging population from the Philippines, have a skewed sex ratio of 1.29 (129 males per 100 females) aged 15 years or under. We hypothesised that this skew was not caused by greater female deaths, but due to an adaptive response, where more males were produced at birth in reaction to high male-biased extrinsic mortality. To test this hypothesis we utilise census, childcare and mortality data from 915 Agta.

May 2019

Journal article - Smith D., et al. (2018) A Friend in Need is a Friend Indeed. Evolution and Human Behaviour.

A recent suite of models based upon ‘cooperative assortativity’ suggest that non-kin cooperation can evolve if individuals preferentially assort with certain cooperative phenotypes, such as helping those who help others. Here, we test these assortative hypotheses among the Agta, a population of Filipino hunter-gatherers, using an experimental resource allocation game in which individuals divide resources between themselves and camp-mates.

January 2019

Journal article - Page, A. E., et al. (2018) Hunter-gatherer health and development policy. Social Science and Medicine.

Recent research in the Agta (Philippine foragers from North-east Luzon) has demonstrated that individuals residing in more ‘developed’ communities suffer from increased morbidity and mortality. Here, using quantitative and ethnographic data on health collected between 2002 and 2014, we explore why this trend occurs by examining the relationship between key development initiatives with self-reported illness and the uptake of medical interventions with 415 Agta men, women and children.

Journal article - Diekmann, Y., et al. (2017) Accurate age estimation in small-scale societies. PNAS

Understanding demographic and evolutionary processes shaping human life history diversity depends on precise age estimations. Inferring age is a challenge in small-scale societies, and especially in those societies that do not follow a calendar year. Our method opens possibilities in demographic and life history studies allowing cross-sectional data to be incorporated in cross-cultural comparisons and a better understanding of the adaptive importance of human life history variation.

Journal article - Salali, G.D, et al. (2016) Knowledge-sharing networks in hunter-gatherers and the evolution of cumulative culture. Current Biology

Journal article - Chaudhary, N. et al. (2016) Within-Group Competition for Cooperation among BaYaka Hunter-Gatherers. Scientific Reports

Competition and cooperation also occur within groups; and inter-individual differences in sociality have reported fitness implications in numerous non-human taxa. Here we investigate whether differential access to cooperation (relational wealth) is likely to lead to variation in fitness at the individual level among BaYaka hunter-gatherers.

July 2016

Journal article - Smith, D. et al. (2016) Camp Stability Predicts Patterns of Hunter-Gatherer Cooperation. Royal Society Open Science

Here we explore cooperation among the Agta, a population of Filipino hunter–gatherers, using data from both actual resource transfers and two experimental games across multiple camps.

Journal article - Page, A. E., et al. (2016) Reproductive trade-offs in extant hunter-gatherers suggest adaptive mechanism for the Neolithic expansion. PNAS

The rise of agriculture during the Neolithic period has paradoxically been associated with worldwide population growth despite increases in disease and mortality. We examine the effects of sedentarization and cultivation on disease load, mortality, and fertility among Agta foragers.

Journal article - Chaudhary, N. et al. (2016) Polygyny without wealth: Popularity in gift games predicts polygyny in BaYaka Pygmies. Royal Society Open Science

In order to elucidate the evolution of hunter–gatherer polygyny, we study marriage patterns of BaYaka Pygmies. We investigate (i) rates of polygyny among BaYaka hunter–gatherers; (ii) whether polygyny confers a fitness benefit to BaYaka men; (iii) in the absence of wealth inequalities, what are the alternative explanations for polygyny among the BaYaka.

Journal article - Dyble, M. et al. (2016) Sex equality can explain the unique social structure of hunter-gatherer bands. Science

Evolutionary theory stresses the importance of living with kin, not least because they share some of our genes. Nevertheless, a large-scale assessment of contemporary hunter-gatherer societies has established a consistent pattern of unrelated individuals living together. Here we used a modelling approach to suggest that a possible answer to this conundrum is that cohabitation choices are being governed equally by men and women.
