In a study recently published in Geochimica et Cosmochimica Acta, an international research team analyzed teeth from 14 different primates, including one human, to better understand the rainfall or water input patterns across their lifetimes.

A bioarcheologist interested in the diets of people long past, UC Davis Ph.D. candidate Diana Malarchik, Department of Anthropology, analyzes the geochemical signatures of teeth to better understand major shifts in breastfeeding and maternal behavior in the past. Her research is highlighting inequities between individuals of high and low socioeconomic status.
