Lifestyle determines gut microbes: Study with modern hunter-gatherers tells tale of bacteria co-evolution

The intestinal bacteria of present-day hunter-gatherers has for the first time been deciphered by an international team of researchers. Bacterial populations have co-evolved with humans over millions of years, and have the potential to help us adapt to new environments and foods. Studies of the Hadza offer an especially rare opportunity for scientists to learn how humans survive by hunting and gathering, in the same environment and using similar foods as our ancestors did.
