Using data from previously published studies to compare the microbiomes of humans, monkeys and others
This observation led scientists to the idea that the intestinal microbiome of human ancestors quickly adapted to new environmental conditions during migration from Africa to other geographical areas.
According to the hypothesis of researchers, the ancestorsmodern people faced a new set of food during migration, which depended on the area of settlement. In addition, ancient people used various methods of treatment, and also faced new diseases.
Adaptive intestinal microbiome helped ancienta person digest or detoxify foods and increased immunity to new diseases, the authors believe. Thus, microbial adaptation has contributed to human success in various environments, which allowed the ancestor of modern people to spread around the world.
Previously researchers at Rutgers Universityfound that the jungle hut is cleaner than the apartments in the city - the first has cleaner air, more sunlight and natural materials, while the apartment has a lot of chemicals from industry and cleaning products, as well as fungus.
