Neolithic Europe is the period when Neolithic technology was present in Europe, roughly between 7000 BCE (the approximate time of the first farming societies in Greece) and c. 1700 BCE (the beginning of the Bronze Age in Scandinavia). 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 the 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 BCE–3000 BCE) while in parts of Northwest Europe it is just under 3,000 years (c. 4500 BCE–1700 BCE).
The spread of the Neolithic from the Near East Neolithic to Europe was first studied quantitatively in the 1970s, when a sufficient number of 14C age determinations for early Neolithic sites had become available. Ammerman and Cavalli-Sforza discovered a linear relationship between the age of an Early Neolithic site and its distance from the conventional source in the Near East (Jericho), thus demonstrating that the Neolithic spread at an average speed of about 1 km/yr. More recent studies confirm these results and yield the speed of 0.6–1.3 km/yr at 95% confidence level.
