The Development of Canonical Proportion as a Function of Community, Multilingualism, and Target Language’s Syllable Complexity
This study investigates the development of canonical proportion (CP), an indicator of speech development, across diverse language and environmental contexts. Using the Speech Maturity Dataset (SMD) comprising 366 children, aged 0;2-6;4, across 10 different languages and cultures, we explore the influence of multilingual exposure, language syllable complexity, and community type (industrialised, non-industrialised) on CP. We find that monolingual …
Does bride price harm women? Using ethnography to think about causality
Many institutions claim that bride price – where the groom's family transfers wealth to the bride's family at marriage – harms women. Owing to its long-term engagement with communities that practise bride price, ethnography is well placed to identify causal mechanisms at play in this issue, and there is a substantial literature on its effects in a variety of world regions, including Melanesia. Here, we condense this literature, drawing out key ca…
Inférences sur les réseaux régionaux à partir d'arbres génétiques locaux, l'exemple du site néolithique de Gurgy 'les Noisats
La reconstitution de la parenté génétique dans des contextes archéologiques a longtemps été impossible, mais grâce à l’optimisation récente des méthodes d’analyse de l’ADN ancien, on peut désormais reconstituer de manière fiable des généalogies génétiques, parfois importantes. L’analyse génomique approfondie du site français du Néolithique moyen de Gurgy 'les Noisats', dans le Bassin parisien, nous a permis de reconstruire deux arbres conséquents…
Vocal input and output among infants in a multilingual context
What are the vocal experiences of children growing up on Malakula island, Vanuatu, where multilingualism is the norm? Long-form audio-recordings captured spontaneous speech behavior by, and around, 38 children (5-33 months, 23 girls) from 11 villages. Automated analyses revealed most children's vocal input came from female adults and other children’s voices, with small contributions from male adult voices. The greatest changes with age involved a…

Infertility, Pooled Reproduction and Distributed Agency Among the Big Nambas of Malakula, Vanuatu
Women’s infertility is an invisible problem in Vanuatu. Assisted reproductive technologies are non-existent. State, medical and NGO actors all promote small families, reflecting global anxieties about population growth and climate change, making infertility conveniently forgettable. Narratives about Vanuatu as a ‘fertile paradise’ make infertility seem uncommon. Anthropological emphasis on flexible kinship suggests that difficulty bearing biologi…
Conformity decreases throughout middle childhood among ni-Vanuatu children
Multiple studies have shown that children conform to majorities in perceptual judgment tasks against their better knowledge. However, these studies report contradictory results about how conformity develops over age. Here, we study variation in conformity over the course of middle childhood: we examined potential informational and normative motivations underlying conformity, as well as intracultural variability in their age patterns. We measured …
Response to “Ancient DNA and its contribution to understanding the human history of the Pacific Islands” (Bedford et al . 2018)
C.P., K.N., H.C., R.G, J.K. and A.P. are funded by the Max Planck Society. A.P. is also funded by European Research Council (ERC) Starting Grant “Waves” (ERC 758967
Digit ratio (2D
OBJECTIVES: Second-to-fourth digit ratio (2D:4D) is proposed as a proxy for the prenatal balance of sex hormones, is related to hormone-dependent characteristics in adult life, and is a possible predictor of disease later in life. Here, we studied the relationship between 2D:4D and ovarian steroid hormones (17β-estradiol and progesterone) among women of reproductive age. METHODS: From 186 healthy premenopausal women, aged 24-37 years, we collecte…
Kin influence on the decision to start using modern contraception
In earlier work in rural Gambia, we found that kin influence reproductive success: matrilineal kin, especially mothers, maternal grandmothers and unmarried older sisters all helped to promote the survival and nutrition of young children; in contrast patrilineal kin, especially husband's mother, promoted fertility. These differing influences of maternal and paternal lineage are predicted on the basis of kin selection and sexual conflict theory, be…
