      Hi there,

      I am wondering how intestinal bacteria came to exist (in humans, or any species for that matter). Many articles discuss the evolutionary pressures that play a part in the development of gut flora, but never suggest any theories as to how they first came to be.

      Any help would be much appreciated. Thanks in advance!

      From a newborn, they start from their mom: The birth canal is not sterile. Then, as neither is their food, it keeps being enriched that way.

      probably has to do with their playing nice with the immune system.

      Symbionts are common in many, many animals, so the basic relationship is ancient.
