Related species are often geographically separate, which prevents intermixing; sister species that share habitats frequently evolve different markings, calls and behaviors through which they distinguish their own kind and avoid crossbreeding. Even most people carry a small quantity of DNA from archaic humans like Neanderthals; in other words, our species, Homo sapiens, has also been influenced by hybridization. In the case of the edible frog, which is the fertile offspring of a pool frog and a marsh frog, it must mate with either a pool frog or a marsh frog to produce more edible frogs.
