Convergent evolution of metabolic functions: Evidence from the gut microbiomes of humans and dogs

open access: yesiMetaOmics, EarlyView.
Dogs have undergone convergent evolution in their genome with humans in long‐term co‐living. Studies have shown that the gut microbiomes of dogs exhibit greater similarity to those of humans compared to mice and pigs. In our study, we first compared the gut microbiomes of macaques, three dog groups, and two wolf groups to those in humans.
