Abstract

In this review, we discuss evidence that the microbes that constitute the human microbiota coevolved with humans and maintain complex community and host interactions. Because these microbes are mostly vertically transmitted, they have evolved within each human group and provide a view of human ancestry. In particular, we discuss using as a marker of ancestry and migrations. Other organisms with more mixed vertical and horizontal transmission are not suitable to trace migrations with any fidelity. Human mixing affects microbial phylogeographic signals, and lifestyles impact the human microbiome population structure. A decade after the human genome was sequenced, we are gaining insights into the population structure of the human microbiome. We also examine whether, rather than focus on the genetics of single microbial populations, a wider approach to the study of human ancestry based on the human microbiome is now possible.
