Do animal classifications change?

              Classifying animals into groups was based entirely on observation initially. Our observation has a limited scope because we rely exclusively on our senses, which can sometimes deceive us. However, today, with modern equipment with more precision and accuracy, Man is able to do this job better.

              Animal classification now uses sophisticated scientific methods to identify relationships among species. Since the methods used to classify animals are continuously changing, there is the probability that the groups in which species are placed may change too. Occasionally, new species are identified!

               For example, until recently, elephants were classified into two species: African and Asian elephants. But DNA studies conducted in 2010 revealed that African elephants actually are of two distinct species- African bush elephants and African forest elephants. This, there are three species of elephants in the world now!
