For many years it was believed that genes and genes alone affected an individual’s microbiome. New evidence, however, indicates that the person or people you are in closest proximity to also play a role.

According to an article via ScienceDaily, a study examining more than 4,000 rats found that both an animal’s genetic makeup and its roommates affected the rats’ gut microbiomes. Though there is much more research to be done, this study shows promising results in this interesting connection. Close family units, partners, and roommates affecting an individual’s gut microbiome may seem like “out there” science, however study of the gut microbiome continues to garner a new and deeper understanding of this complex system.

The microbiome is related to immune function, metabolism, and in some cases, behavior. The article stated that genetic studies using animal models can help provide testable explanations on how genes and gut microbes interact.
