The most recent common ancestor (MRCA) of bacteria and archaea was probably a hyperthermophile that lived about 2.5 billion–3.2 billion years ago. [ 16 ] [ 17 ] [ 18 ] The earliest life on land may have been bacteria some 3.22 billion years ago.

The temperature and pH of saliva makes it conducive for bacteria to survive in the oral cavity. Bacteria in the oral cavity include Streptococcus mutans, Porphyromonas gingivalis, and Staphylococcus. [15] S. mutans is the main component of the oral microbiota. [15] A healthy oral microbiome decreases oral infections and promotes a healthy gut ...
Some of the most common bugs that contaminate food include E. coli, salmonella, campylobacter, staphylococcus, listeria and norovirus. Though most any food can become contaminated with bacteria or ...
It is possible that the last common ancestor of the bacteria and archaea was a thermophile, which raises the possibility that lower temperatures are "extreme environments" in archaeal terms, and organisms that live in cooler environments appeared only later. [49]
