“…If this is the case, the relative contributions of trace elements from human and nonhuman animal milk would be similar, interfering with the reconstruction of weaning ages. Although few studies have evaluated the contributions of nonhuman animal milk to infant tissues, the combination of several geochemical signals is a good strategy to detect and interpret the possibility of consuming special weaning foods (Wright andSchwarcz, 1998, 1999;Dupras et al, 2001;Williams et al, 2005;Fuller et al, 2006b;Nehlich et al, 2011;. Furthermore, the carbon isotope analysis of lipid residues preserved in archaeological pottery-a direct proxy of nonhuman animal milk use in prehistory (e.g., Dudd and Evershed, 1998;Copley et al, 2003;Evershed et al, 2008)-provides a qualitative contribution to the reconstruction of animal milk supplementation in infants.…”

Biogeochemical methods using stable isotopes and trace elements have been increasingly developed and applied to reconstruct modern and ancient breastfeeding and weaning practices of mammals, including humans, because they offer direct proxies for the dietary intake of subadults. Carbon, nitrogen, and oxygen isotopes have been used to evaluate breast milk lipid, protein, and water intake, respectively. Carbon and sulfur isotopes have been used to estimate the content of weaning foods. The elemental concentrations of Sr and Ba in subadult tissues differ because of the dietary change during the weaning process. For analyses, various tissues have been used, such as hair, nail, blood, and feces for modern mammals and bone and teeth for ancient ones. Of these, trace element analysis of tooth enamel offers a good opportunity for the reconstruction of breastfeeding and weaning practices of the more distant past at finer resolution, although further understanding of the metabolism of trace elements is necessary. There are various tissue-and element-specific advantages and disadvantages, and a combination of different proxies can illuminate practices from various viewpoints. Finally, applying the geochemical reconstruction of breastfeeding and weaning practices to human ecology, primatology, and paleoanthropology is important; basic studies of the underlying physiological mechanisms and technical improvements in the analyses will further highlight avenues for future research.

V C 2014 American Association of Physical AnthropologistsThe reconstruction of breastfeeding and weaning practices (BWPs) of ancient human and other mammalian species is one of the most important fields in anthropology, archaeology, evolutionary biology, and history. Infant feeding practices affect the overall health of the population because diet, health status, and growth at a young age have profound effects on an individual's later life (Dettwyler and Fishman, 1992;Katzenberg et al., 1996;WHO, 1998WHO, , 2009Lewis, 2007). Breastfeeding and weaning practices can be viewed from the evolutionary perspectives of life history theory, parental investment, child development, social system, and reproductive strat-

“…While the δ 13 C values of bone and dentin collagen mostly reflect those of a dietary protein (Ambrose and Norr, 1993), the δ 13 C values of enamel apatite reflect those of total dietary carbon including carbohydrates, lipids, and protein (Krueger and Sullivan, 1984;Jim et al, 2004;Kellner and Schoeninger, 2007). The breastfeeding period and carbohydrate supplementation in subadult diet have been studied by using oxygen and carbon isotope analyses of tooth enamel (Wright and Schwarcz, 1998;Wright, 2013;Garcia et al, 2015).…”

The life history of a female individual skeleton (ST61) from the Edo period (AD 1603(AD -1868 was investigated by using multi-tissue and multi-isotope analyses. Her gravestone and historical documents revealed that ST61 was a grandmother of a chief retainer of the Akashi clan who died in 1732 aged 77 years. Radiocarbon and sulfur stable isotope analyses indicated that the contribution of marine foods to the ST61 diet was relatively low (17.2% protein) despite the relatively higher nitrogen isotope ratio of the rib bone collagen. Carbon and nitrogen stable isotope analysis of the serial section of tooth dentin along the growth lines indicated that breast milk was not the major protein source of ST61 after roughly 1-1.5 years of age, although this weaning pattern was not evident from the oxygen stable isotope ratios of her tooth enamel serial sections. The carbon stable isotopes in tooth dentin collagen and tooth enamel apatite suggested that her diet from 0.5 to 5 years of age possibly contained a small proportion of C 4 plants. Stable isotope ratios of the rib bone and the tooth dentin collagen differed, consistent with historical documents describing a residential change at the age of 27. The calibrated radiocarbon ages of the associated rice hull were at least 80-120 years older than the year of death of ST61. Sulfur stable isotope ratio of the rice hull suggested that fish fertilizers might have been used for paddy rice at that time. Multi-tissue and multi-isotope analyses can provide information of several kinds from different time windows even from an individual skeleton.
