Overview
Research indicates that the trillions of microorganisms comprising the human gut microbiome accompanied humans during their migrations out of Africa, a process that spanned tens of thousands of years and ultimately led to the populating of various continents. Genetic analysis suggests a correlation between the evolutionary history of the human gut microbiome and ancient human population movements.
Research Context
The gut microbiome, a complex ecosystem of microorganisms, has been a long-term associate of humans. Its presence with human populations during intercontinental dispersal events implies a co-migration dynamic. This research explores the genetic links between the gut microbiota and the historical trajectories of human populations across the globe.
Findings
- Analysis suggests that the gut microbiome traveled with human populations as they dispersed from Africa.
- Genetic analysis indicates ancient ties between gut bacteria and human migrations across continents.
