Furthermore, it is likely that the evolution of these organ system niches drove radiation of particular clades of animal-associated bacteria ( 15 such as the genus Helicobacter in vertebrate guts ( 16 ). This has been linked primarily to solar UVB through the production of vitamin D, and, to a lesser extent, increased consumption of dietary fat with latitude.
