...sor. "As adults, the number of these bacterial and archaeal microbial cells exceeds the number of our human cells by tenfold. The genes present in this community of 10-100 trillion bugs vastly outnumber our own genes and are a key part of our genetic landscape, providing us with attributes we have not had to ...Ammonia-loving archaea win landslide majority
