Why are names important in science? What is the difference between scientific names (also known as Latin names or taxonomic names) and common names? Why do some species have multiple names? The grant project team for What’s in a Name, supported by the Institute of Museum and Library Services (IMLS), set out to find answers and develop exhibits and other ways for anyone to explore this phenomenon. With millions of different species to identify and understand, the process of naming organisms helps scientists organize and understand the tree of life.
