The middle pleistocene and the late pleistocene correspond to which cultural periods?
Crank

The middle stone age and the later stone age corresponds to the middle and the late pleistocene.

Cultural evolution during the middle and the late pleistocene :-

In southwestern Asia as well as northern and southern Africa, personal ornaments in the form of perforated seashells are recorded from the early Late Pleistocene. In the Old World, Neanderthals and anatomically modern humans are linked to a range of personal ornamentation by about 40,000 years ago (Ka). These include fully created ornaments as well as organically modified things. The appearance of figurative art, mythical imagery, and other types of items, like as musical instruments, at various times in history suggest that completely modern behavior began to emerge more gradually towards the middle of the Late Pleistocene and most definitely no later than 40 Ka. Many, but not all, of the lengthy and rigorous history of study might well have helped to the relevant data come from Europe.
