O litoral do nordeste do Brasil como objeto científico darwinista: as prospecções de John Casper Branner, 1899-1911

Abstract

John Casper Branner, a US geologist, had a long history of research in Brazil. The article analyzes his exploration of the geology of the coast of Northeast Brazil during the Branner-Agassiz (1899) and Stanford (1911) expeditions. In the findings from both voyages, Branner characterized the geomorphology of sedimentary basins, sandstone reefs, and coral reefs from a Darwinian evolutionary perspective, blending natural history’s model of field research with the practices of modern biology and dynamic geology. He based his interpretation of the evolution of the geological formation on physical and chemical factors. Zoological studies identified the place of evolutionary variation and adaptations of isolated marine species as an auxiliary factor in natural selection.
