Heatmap showing patterns of various genera present in gut microbiome of individuals belonging to different age groups. In spite of being cross-geographic, the gut microbiomes of individuals belonging to the six different age groups cluster into two distinct groups. While the first group consists of the younger age groups (G1: 0–10 years, G2: 10–30 years and G3: 30–40 years), the second group consists of the older age groups (G4: 40–50 years, G5: 50–60 years and G6: 60 years and above). Red color signifies that the genus is either absent or present in low abundance, whereas the green color signifies that it is highly abundant
