Please Pass the Microbes

Importantly, the Hadza don't keep livestock or plant foods of any kind, and have limited access to modern medications like antibiotics (at least the more remote Hadza camps that we are studying). While some may argue that the Hadza are not perfect referents for the way it once was, it depends on the questions you are asking. For our purposes, studying how humans acquire microbes from birth throughout life (from others and the larger meta community of microbes in nature) in a group where babies are all still born naturally (no c-sections), are breastfed on average for 2+ years, where children still sleep with their mothers years beyond weaning, take no antibiotics, don’t drink water that has been treated with chlorine and fluoride, where multiple generations stay together (not separating the seniors into assisted living facilities), don't eat processed foods, and newborns to the eldest in the community are still covered in nature’s blanket of everything that comes from living outside 24/7 and interacting in an intimate way with 100s of species of plants and animals.
