15.1 Taxonomy and Systematics
• Scientists classify organisms according to their characteristics and evolutionary relationships.
• This process is called systematics.

15.1 Taxonomy and Systematics• A Swedish scientist and explorer named
Carolus Linnaeus (1707–1778) developed a system of classification called taxonomy in the 1700s.
• Linnaeus classified living things according to their shared characteristics.
• There are currently seven levels of classification.

15.1 Scientific Names
• A scientific name is the two-part, scientifically recognized name given to an organism, consisting of its genus and species.

15.1 Scientific Names
• You may have a difficult time understanding scientific names because they are usually in Latin or Greek.
• Felis is Latin for “cat” and domesticus is Latin for “domesticated.”

15.1 What is systematics?
• Darwin’s theory of evolution led to the development of systematics.
• Systematics is the process of classifying living things according to evolutionary relationships.
• Today, scientists may use DNA analysis to classify living species.

15.1 What is systematics?
• The evolutionary development of primates can be shown on a simple cladogram.
• The characteristics listed along the right distinguish the levels above each node (the point where two branches meet).
• The nodes indicate a common ancestor between two groups.

15.1 Evolution and the six kingdoms
• An evolutionary tree is a diagram with many branches that shows evolutionary relationships among organisms, both living and extinct.
• In a complete evolutionary tree, the levels of classification (phylum, class, order, etc.) would branch off from each kingdom all the way down to the species level.
