Classification grouping of different types of organisms based

Classification grouping of different types of organisms based upon similarities in structure and evolutionary relationships

Sample Question • In this process, which of the following would be most useful? a. watching the feeding habits of similar organisms. b. studying the skeletal structure of different organisms c. studying the environments in which different organisms are found d. performing a DNA analysis of different organisms

WHY CLASSIFY? • In order to more easily study the unity and diversity of living organisms in an organized manner, biologists classify organisms • This means that they group organisms together based on their common characteristics • Physical structure is often the primary basis for biological classification

MODERN CLASSIFICATION SYSTEM: • • KINGDOM PHYLLUM CLASS ORDER FAMILY GENUS SPECIES
