Why intruduce a scientific name?

Answer 1

Common names vary greatly from one location to another. One example is the mountain lion, also known as the puma and cougar, as well as several other common names. However, scientific names are the same worldwide. The scientific name of the puma/cougar/mountain lion is Puma concolor. So if you want to talk to other scientists about this animal, you would use the scientific name rather than the common name to avoid confusion.
