Concept explainers
Describe the steps involved in allopatric speciation.
Definition Definition Process by which new species arise. This occurs when populations of a species become isolated and diverge, developing unique traits through natural selection, genetic drift, or other mechanisms. Over time, these differences accumulate until the populations can no longer interbreed and are considered separate species.
