Anatolian Neolithic population migrated to Balkans from 7th millennium BC, merging with local Mesolithic groups. Early Neolithic pottery in west Bulgaria features tulip-shaped painted ceramics. Thrace Karanovo culture has red-brown tulip cups and geometric ornaments. North Bulgaria pottery is black polished with zigzag flutes. Late Neolithic introduces cylindrical cups and thick water-jugs. Anthropomorphic figurines evolve from small stylistic to seated females with joined legs and beak noses. Thrace features tell mounds, west Bulgaria few tells, north open sites. Houses built with interwoven sticks and clay, some stone in Durankulak. Young buried under house floors or in pottery, later necropolises like Durankulak. Chalcolithic introduces copper smelting for tools boosting agricultural surplus. Copper exports from Balkans to Black Sea north coast. Varna necropolis shows extreme wealth gaps with rich chieftain graves. Copper tools dull quickly but enable trade and social complexity. Advanced stone houses signal emerging civilization. Chalcolithic ends with bronze invention around 3rd millennium BC.
