I want to know the answer to the following question:
Olduwan, Mousterian, and Levalloisian are all types of what?
All the background I'm provided with is that "Further cultural subdivisions according to tool types, such as Olduwan or Mousterian or Levalloisian help archaeologists and other anthropologists in understanding major trends in the human past.[citation needed]". Is that enough to answer the question?
