What is the Value of Classifying Organisms? • 1. Aiding the identification of species – When confronted with an unidentified species, scientists look at classification keys which give hints to help provide a name for it.

• 2. Shows evolutionary links – Species in the same group usually share characteristics since they have descended from a common ancestor. Classification can be used to predict how they evolved.

• 3. Predicting characteristics shared by similar species – If several species in a group share a characteristic, another species in the group will probably share that characteristic.
![What is a Species? • A species is a group of organisms with similar What is a Species? • A species is a group of organisms with similar](http://slidetodoc.com/presentation_image_h2/c8b1dadb53a3a2c7d1b671d2469e5ee0/image-6.jpg)
What is a Species? • A species is a group of organisms with similar characteristics, which can interbreed and produce fertile offspring. Their DNA will also be very similar.
![Binomial System of Nomenclature: • All identified species are given an international name, so Binomial System of Nomenclature: • All identified species are given an international name, so](http://slidetodoc.com/presentation_image_h2/c8b1dadb53a3a2c7d1b671d2469e5ee0/image-7.jpg)
Binomial System of Nomenclature: • All identified species are given an international name, so scientists around the world can refer to it. The naming system that scientists use to name species is known as the binomial system since 2 names are used to refer to each species.
