Scientists assign all living organisms a Latin name, also called the binomial name.  Using Latin avoids confusion caused when people from different places, speaking different languages, use different names to talk about the same animal or the same name to talk about different animals. For example some people call Cathartes aura turkey vultures, while others call them buzzards. The process of organizing organisms into groups (taxons) by shared characteristics is called "taxonomy".  These taxonomic groups work from the most general characteristics to specific traits, and reflect how creatures are related through evolution.
