There is a related thread here: Scientific name Vs. Common name?
I think both common names and scientific names have their uses. Common Names are generally easier to remember and are likely more meaningful when communicating with a general audience. However, common names are not global and often the same common name can apply to multiple (sometimes many) unrelated species. I work as a research coordinator and I coordinate ~50 biologists across the eastern U.S. For birds, we use common names because North America has standardized common names for birds. However, we use scientific names for plants because 50 biologists may have 20 different common names for the same plant.
