Which of the following statements best describes the findings of the recent study on Indian tribal gut microbiomes?

Dietary habits, such as dairy consumption, exert evolutionary selection pressure on gut microbial composition.

The study concluded that probiotics are universally effective regardless of an individual's traditional diet.

Bifidobacterium adolescentis is the only marker of a healthy gut microbiome across all human populations.

Tribal gut microbiomes are identical to those found in industrialized Western populations.

Tribal Gut Microbiome Research

The research provides scientific context on the biological diversity of Indian tribal populations and the importance of indigenous knowledge, which can be used as illustrative evidence in answers regarding Indian society or advancements in biotechnology.

Notes

A study published in 'Gut Microbes' analyzed the gut microbiomes of eight Indian tribal populations (Warli, Madia, Gond, Kabui, Brokpa, Purigpa, Balti, and Boto).
The study highlights that gut microbial diversity is significantly shaped by long-term dietary habits and is distinct from industrialized populations.
Trans-Himalayan tribes (high dairy and grain intake) showed higher microbial diversity and an enrichment of 'Bifidobacterium adolescentis'.
Non-trans-Himalayan tribes (fish, fruits, greens, home-brewed alcohol) exhibited different microbial compositions, suggesting diverse pathways for achieving gut health.
The study identified 14 putatively novel bacterial taxa from 76 healthy adult participants.
Researchers emphasize the need for biobanking these unique microbial communities before they disappear due to changing lifestyles.
The findings underscore that probiotics and dietary interventions must be tailored to specific population diets and gut compositions.
The Indian Human Microbiome Initiative aims to sample over 3,400 individuals across 10 endogamous and 7 tribal communities to build a representative database.

This is day 2 of 2 in Indian Tribal Gut Microbiome Research, which has been running since 26 July 2026. Reading it whole is usually worth more than reading today alone — the exam asks how something developed.
