It was decided so use Latin for the scientific names, as it was the language use centuries ago by learned people. Carl linnaeus was the man who established the modern scientific method for naming plants and animals. Scientific names are in two parts. The first part is the generic name, which describes a group of related living things. The second name is the specific name, which applies only to that living thing. This specific name may describe the living thing, or it could include the name of the person who discovered it.
