I have created a new map showing the approximate spread of the Chalcolithic (Copper Age) from the Middle East and the Balkano-Carpathians to the rest of Europe. Please let me know if you find any inconsistency (provide supporting data).
The oldest evidence of copper metallurgy is from the Vinča culture in Serbia around 5500 BCE. From there is quickly spread to Bulgaria (Gumelniţa-Karanovo culture, etc.), then to the Carpathians (Cucuteni-Tripyllian culture) and the Danubian basin. These cultures of 'Old Europe' would have included haplogroups E1b1b, G2a, J and T (as well as I2a1 for Cucuteni-Tripyllian).
The Khvalynsk culture in the Volga region marks the first appearance of the chalcolithic in the steppe. Copper working quickly spread in the Pontic-Caspian Steppe and associated cultures further north (Fatyanovo–Balanovo culture) and west (Corded Ware culture). This dispersal was of course linked to haplogroups R1b and R1a.
It is noteworthy that the Maykop culture in the North Caucasus (from 3800 BCE) immediately started off as a Bronze Age culture, and apparently the world's oldest.
The Iberian Copper Age
I am wondering how the Copper Age started so early in southern Iberia compared to the rest of Atlantic and Mediterranean Europe. The Bell Beaker people, who seem to have originated in Portugal, are mostly responsible for the diffusion of the Chalcolithic around the Megalithic cultures of western Europe.
I am starting to think that the Chalcolithic may have been brought directly from the Near East to southern Iberia via Sicily by J2 people. That would make sense for five reasons:
1) it is unlikely that the Copper Age started independently in southern Iberia and nowhere else in Europe. Anatolia and Syria was the first region to develop copper metallurgy outside the Balkans. Both regions have a high percentage of haplogroup J2. Obviously the percentage of J2 in Serbia and Romania has diminished after millennia of invasions from the steppes and from other parts of Europe. Mountain-sheltered Kosovo and Albania are generally considered to be closer to the pre-Indo-European population of the Balkans, and both have a lot of J2.
2) Agriculture was spread along the Mediterranean coasts from the Levant and reached southern Iberia as early as the Neolithic spread by land along the Danube in central Europe. This is a proof that maritime diffusion can spread new technologies much faster than on land.
3) I long wondered how haplogroup J2 propagated outside West Asia, as its distribution in Europe appears less correlated with the Neolithic than other haplogroups (E1b1b, G2a, J1, T). I had postulated a Bronze Age expansion from Anatolia to Greece, the eastern Balkans and Italy. But why not a Chalcolithic expansion since the Bronze Age is so closely linked to haplogroups R1a and R1b ? Furthermore there happen to be a hotspot of J2 in southern Iberia, which would be much better explained by a Copper Age migration than merely by Phoenician settlements.
4) The Copper Age started earlier in southern Italy than in central or northern Italy. The dominant lineage in southern Italy is J2.
5) Based on all the ancient mtDNA samples tested so far, the main difference between Neolithic and Chalcolithic lineages is the greatly increased frequency of haplogroups J1, K and X, three lineages which are particularly common today in Greece, Bulgaria, Turkey, Armenia and Georgia. This also corresponds to the region from which the Copper Age emerged, which proves that there was also a certain amount of gene flow linked to the diffusion of the copper metallurgy. This regions also happens to be the one where haplogroup J2 is the most common.
EDIT : Since there was little cultural or societal change from the Neolithic to the Chalcolithic, apart perhaps a little more prestige goods in some graves, I'd think that copper metallurgy was spread fairly peacefully by a minority of immigrants, except for the Corded Ware culture and the steppes. The Bronze Age diffusion might have been more violent justly because of the more individualistic, hierarchical and paternalistic culture of the Indo-Europeans.
