Terra Avita Region and Era Name Link	Event Description
Neolithic Africa (beyond the Nile)	Sahara still green but drying begins; pastoralism spreads widely through eastern and central Sahara; cattle-based societies form; rock art prolific.
Neolithic Central America	Early domestication centers forming; proto-maize emerging in southwestern Mexico; small sedentary villages appear shortly after this window.
Neolithic China (East Asia)	Neolithic cultures split into regional clusters: Yangshao in the north (millet agriculture, painted pottery) and Hemudu in the south (early rice-based village systems).
Neolithic Eastern Mediterranean	Late Neolithic and early Chalcolithic; large village complexes (Çatalhöyük waning, Jericho evolving); copper use rises; first proto-urban social stratification begins.
Neolithic Egypt	Badarian culture near its start (circa 4400 BC); early agriculture along the Nile; fine pottery, cattle pastoralism, and grave goods show rising social complexity.
Neolithic India and Central Asia	Mehrgarh Phase III in Baluchistan; established agriculture (wheat/barley), domesticated cattle, and large mud-brick villages; craft specialization increases.
Neolithic North America	Late Archaic in many regions; broad-spectrum foraging; mound traditions beginning in Southeast U.S.; early plant domestication (sunflower, goosefoot) in eastern woodlands.
Neolithic Oceania	Australia remains forager-based; rich ritual cultures and rock art; Tasmania isolated by rising seas; New Guinea shows developed horticulture (taro, yam), early drainage systems.
Neolithic Persia	Chalcolithic Iran emerges; settlements in Zagros and Iranian Plateau grow; early irrigation and painted pottery cultures (e.g., Ubaid influence toward west, local developments in east).
Neolithic South America	Early agriculture begins in some regions (Andean potato and quinoa precursors, coastal Peru horticulture); widespread maritime foraging along Pacific coast.
Neolithic Western Europe	Fully Neolithic across most of Europe; farming communities spread from Danube and Mediterranean; Megalithic traditions begin forming in Atlantic Europe; polished stone tools common.

Terra Avita Region and Era Name Link	Event Description
Chalcolithic Africa (beyond the Nile)	The Green Sahara collapses toward aridization. Pastoralist societies retreat into Sahel bands and Nile corridor. Cattle culture persists; major rock art traditions (Tassili n’Ajjer) near peak expression.
Chalcolithic Central America	Proto-agricultural villages emerging in southern Mexico. Early maize cultivation recognizable but not yet dominant. First durable sedentary sites begin to consolidate.
Chalcolithic China (East Asia)	Yangshao culture declining; Longshan culture rising—marked by walled settlements, social stratification, black pottery, and emerging political centralization. North: millet agriculture strong; South: rice agriculture expands.
Chalcolithic Eastern Mediterranean	Rise of the first true urban civilizations. Egypt enters the Early Dynastic period; Sumerian city-states (Ur, Uruk, Lagash) are in full Bronze Age development; writing systems fully operational (cuneiform, hieroglyphs).
Chalcolithic Egypt	Transition from Predynastic → Early Dynastic. Narmer unifies Upper and Lower Egypt around 3100 BC. Kingship, hieroglyphic writing, large-scale agriculture, monumental ceremonial architecture (early mastabas) begin.
Chalcolithic India and Central Asia	Mature village-based farming systems. In the northwest, early Harappan (Pre-Indus) cultural foundations emerging; planned settlements, craft specialization, long-distance trade networks forming.
Chalcolithic North America	Late Archaic period. Regional plant domestication spreads (sunflower, marsh elder). Large-scale trade networks (eastern woodlands). Shell mound complexes along coasts. No agriculture except in very early proto-forms.
Chalcolithic Oceania	Australia remains hunter-gatherer with highly developed regional cultures; Tasmania fully isolated. New Guinea maintains advanced horticulture—taro, banana, and early irrigation structures in highlands.
Chalcolithic Persia	Proto-Elamite civilization active in southwestern Iran; administrative tablets and early writing systems appear. Settlements grow across the Iranian Plateau; copper metallurgy spreads widely.
Chalcolithic South America	Early Andean agricultural societies forming—potato, quinoa, llama domestication increasing. Norte Chico (Caral-Supe) civilization beginning to rise around 3000–2600 BC along Peru’s coast.
Chalcolithic Western Europe	Western Europe enters the Late Neolithic / Early Bronze horizon. Megalithic cultures flourish (Stonehenge’s earliest phases, Newgrange already built). Farming is dominant; metallurgy begins to appear in Iberia and the Balkans.
