Instead of giving organisms common names that reflect their physical appearance, behaviour or habitat, the binomial system is used.Each species has a scientific name that consists of two parts: the genus and species.No two species have the same generic and specific name. The names are printed in italics e.g. Homo sapiens or underlined if handwritten.The generic name begins with a capital letter and the specific name begins with a small letter.
