Stone Age quiz: What do you know about the Paleolithic, Mesolithic and Neolithic?

The Stone Age was a prehistoric period that lasted more than 3 million years, from the point when human ancestors began using stone tools until the time we invented metalworking.

Archaeologists often break up this lengthy time span into three periods — the Paleolithic (3.3 million to 12,000 years ago), the Mesolithic (12,000 to 10,000 years ago), and the Neolithic (10,000 to 4,000 years ago) — although there is regional variation in dates.
