Today, Dr. Laura Weyrich, Associate Professor of Anthropology at Pennsylvania State University,  joins the #QualityQuorum to discuss the paleo oral microbiome! We will learn if our ancestors had the same kind of resident microbes as we do. In addition, we will learn about ancient DNA and what it can tell us.
