RESUMO
John Casper Branner, geólogo norte-americano, desenvolveu uma longa história de investigação no Brasil. Analisa-se, aqui, como ele tratou a geologia do litoral do Nordeste na Branner-Agassiz Expedition (1899) e na Stanford Expedition (1911). As expedições indicam como a geomorfologia das bacias sedimentares, dos recifes de arenito e dos recifes de corais foi caracterizada sob uma perspectiva evolutiva darwinista. Branner integrou o modelo de pesquisa de campo da história natural com as práticas da biologia moderna e da geologia dinâmica, e interpretou a evolução da formação geológica a partir dos fatores físico-químicos. Os estudos zoológicos identificaram o lugar da variação e das adaptações evolutivas das espécies marinhas isoladas como fator auxiliar da seleção natural.
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.
