Charles Darwin
Geological Observations on South America
"Geological Observations on South America" by Charles Darwin is a scientific book published in 1846. Based on Darwin's travels aboard HMS Beagle, it documents the continent's geological features, fossils, and rock formations across Chile, Brazil, and Argentina. The third in Darwin's geology series, it presents groundbreaking observations about the Andes' uplift and South America's gradual elevation. Though Darwin himself called it "dreadfully dull," the work advanced geological understanding of continental formation during recent geological periods.
