The Neolithic overlaps the Mesolithic and Bronze Age periods in Europe as cultural changes moved from the southeast to northwest at about 1 km/year - this is called Neolithic Expansion. The duration of the Neolithic varies from place to place, its end marked by the introduction of bronze implements: in southeast Europe it is approximately 4,000 years (i.e. 7000
