Livestock is given B12 supplements. B12 only occurs naturally in soil, where the concentrations are too low for even animals to bind. Prehistoric humans probably ate more dirt and had enough of it.

>B12 only occurs naturally in soil

LOL. Patently false. B12 is produced by bacteria in herbivores' guts.
