It seems that humans got Ruminococcus hominiciens (bacteria that is pivotal for brealing down celulosis) only after domesticating cows etc. > Our evolutionary analysis strongly suggests that R[uminococcus] hominiciens likely originated in the ruminant gut and later transferred to humans, possibly during domestication. > The human-associated strains possess functional adaptability highlighted by the acquisition of genes that can degrade specific plant fibers of monocots such as maize, rice, and wheat—major components of the human diet. https://www.science.org/doi/10.1126/science.adj9223 https://www.science.org/doi/10.1126/science.adj9223
