Brazil's immense area is subdivided into different ecoregions in several kinds of biomes.Because of the wide variety of habitats in Brazil, from the jungles of the Amazon Rainforest and the Atlantic Forest (which includes Atlantic Coast restingas), to the tropical savanna of the Cerrado, to the xeric shrubland of the Caatinga, to the world's largest wetland area, the Pantanal, there exists a ...
The savannah hypothesis (or savanna hypothesis) is a hypothesis that human bipedalism evolved as a direct result of human ancestors' transition from an arboreal lifestyle to one on the savannas.

A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close.
Flooded grasslands and savannas is a terrestrial biome of the World Wide Fund for Nature (WWF) biogeographical system, consisting of large expanses or complexes of flooded grasslands. These areas support numerous plants and animals adapted to the unique hydrologic regimes and soil conditions.
Anole lizards, with populations on isolated islands, are one of the best examples of both adaptive radiation and convergent evolution. Anoles on a given island evolve into multiple body types and ecological preferences, and the same set of body types appears in unrelated species across distant islands. [93]
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. [1] The biome is dominated by grass and/or shrubs located in semi-arid to semi- humid climate regions of subtropical and tropical latitudes .
Botswana is around 90% covered in savanna, varying from shrub savanna in the southwest in the dry areas to tree savanna consisting of trees and grass in the wetter areas. [1] Even under the hot conditions of the Kalahari Desert, many species survive; in fact the country has more than 2500 species of plants and 650 species of trees. [2]
The forest-savanna mosaic interlaces forest, savanna and grassland habitats. Northern Ivory Coast is part of the Sudanian Savanna ecoregion of the Tropical and subtropical grasslands, savannas, and shrublands biome. It is a zone of lateritic or sandy soils, with vegetation decreasing from south to north. [2]
