"History" itself now refers to the entire Universe timeline before the present. But prehistory cannot mean that, because that would be pre-BigBang.
So the title "Prehistoric babies Drank Animal Milk from Bottles" could refer to 1491 born Guaraní babies drinking Llama's milk from ceramic bottles and a nipple made from the rubber tree. Cool, but of no relevance to a paleo-diet.
"The terms "Neolithic" and "Bronze Age" are culture-specific and are mostly limited to cultures of the Old World."
