Just to show its tough and complicated but the real answer is that there are lots of species of animals and other organisms so giving scientific names maybe gets a lot of different animals under the same group and at same time differs it from other organisms it just helps the biologists and scientists in their work
Scientific names are important because they allow people around the world to communicate accurately about animal species. With the help of international rules on naming animals, zoologists avoid naming the same species twice. This means that each scientific name is unique.
