The Geographic Basis of Evolution

The geographic basis of evolution refers to how a species' physical location influences its development over time. When populations of a species are separated by barriers like mountains, rivers, or distance, they experience different environments and challenges. Over generations, these groups adapt uniquely to their specific habitats, leading to genetic differences. If they remain separated long enough, they can become so distinct that they stop interbreeding, eventually resulting in new species. Basically, geography shapes the diversity of life by creating conditions for separate evolutionary paths.
