| Research Abstract |
In this research, we investigated the impact of shortening breast-feeding period on the population growth which observed at the introduction of agriculture in prehistoric period of Japan. Three different approaches including collagen isotope analysis, enamel hypoplasia, and the population analysis of infants have been tested to estimate the length of breast-feeding. The estimation have not agree to each other using conventional methods, but some methodological arrangements can improve each estimation. Preliminary results suggested the Jomon hunter-gatherers had variable practices of breast feeding and weaning processes.
