[16] [17] [18] The earliest life on land may have been bacteria some 3.22 billion years ago. [19] Bacteria were also involved in the second great evolutionary divergence, that of the archaea and ...
Graphic depicting the human skin microbiota, with relative prevalences of various classes of bacteria. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung ...
