Interesting Fact:

Only a fraction of all the existing life forms have been identified. To fill in our picture of the living world, biologists search for new species -- groups of organisms that reproduce with one another and share a common evolutionary history. Once a new species has been identified, biologists give it a name that reflects its relationship to other species.
