Geographic Foundations (Prehistory–1491)
Deep-time formation and major biomes
Amazon Basin develops as one of the world’s largest tropical rainforest systems, anchored by the Amazon River network and vast floodplains
Atlantic Forest (Mata Atlântica) forms along the coast, later becoming one of the most biodiverse—and most heavily reduced—biomes
Cerrado savanna expands across central Brazil; Pantanal wetlands take shape in the Upper Paraguay River basin; Caatinga semi-arid scrub develops in the Northeast
Highlands and plateaus (Brazilian Highlands) dominate much of the interior, shaping river headwaters and settlement patterns
Indigenous societies and regional adaptations
Diverse Indigenous peoples establish cultures suited to different environments: riverine Amazon communities, coastal groups along the Atlantic, and interior plateau societies
Long-distance exchange networks develop (stone, ceramics, food crops), linking coast, forest, and savanna regions
Land-use practices (managed forests, agroforestry, controlled burning in some regions) shape local ecologies
