SciencePhoto: Mongabay IndiaColumbus Voyages Accelerated Global Biodiversity Homogenization
Christopher Columbus's 15th-century voyages initiated large-scale biogeographical homogenization by enabling unprecedented cross-boundary human and organism movement. Over 500 years, this led to major shifts in the distribution of microorganisms, plants, and animals. Introduced invasive species and pathogenic microorganisms caused widespread harm, including the decimation of indigenous populations and agricultural devastation, profoundly transforming Earth's biodiversity.
