It is sufficient to use common names of plants and animals when we are talking about a group of people talking in the same language in which the names are used. But when people from different countries, continents come together then it becomes a problem when a specific language known only to some are used to name different species. So for facing this problem we have internationally accepted rules for naming the plants and animals in a common language – Latin. The names are same in every country and continent and hence it becomes easy to identify a particular species among people of different places.
Different animals and plants have different local names. These local or regional names may not be known by people from other geographical region. This can cause confusion when dealing with the organism on a global level so for better understanding and to avoid confusion scientific names are used. Also scientific names give us a rough idea about the structure and characteristics of the organism that we get from the species and the genus name.
Common name varies from one place to other place. For example, in India, dog is called by using different common names in different languages. Like Kutha in Hindi, Kukka in Telugu, Naayi in Kannada, Patti in Malayalam.
If a person in India writes a research article on dog by using its common name, how can a person reading it in England can understand. If we use a scientific name all over the world, like dog’s scientific name is Canis lupus, anyone can understand.
because there is many common names to the plants in different country. some cases the plant species has many common names in the different regions of the same country. Whereas there is one scientific name for each plant or animal. for example it can called wheat, grist, flour , Kamh etc…
It is to make the study of classification of plants and organisms easy. For example, when indian students will study classification, they will use ‘aaloo’ for potato, in germany it will be studied as’kartoffel’, in france as ‘patate’ and so on. And then think of a situation when there will be a scientific research on any plant or organism, scientists of different countries will come together for research and they will be using common names of plants and organisms in their own languages. How the research gonna proceed??? Hence, the scientific names are used to describe various species of organisms in a way that is universal so that scientists around the globe can readily identify the same organism.
Common name system has a lot of problems and confusions, because the name used in one part of the world is not understood by any person from other part.
As common name for apple in kashmiri is’chount’ in pakistan it is called ‘saib’ and so is the other parts of country and so by the many parts of world.
So un order to compensate the system a world wide union came into existance in order to facilitate the system of nomenclature. And so all the world would mean the particular name to particular thing.
