Ancestral bacteria in our intestines

An international team of researchers has discovered in great apes (chimpanzees, gorillas and bonobos) and in 16 humans that their intestines welcomed two ancestral families of bacteria: the Bacteroidaceae and the Bifidobacteriaceae. These 15 million year old bacteria (when humans didn’t even exist), have evolved in response to the drift of continental plates and to adapt to the environment.
