    1. 1. ClassificationConceptual - Biology -Chapter 1.4 Chapter 18
    2. 2. I. Why Classify?
    3. 3. I. Why Classify? A. Why group things?
    4. 4. I. Why Classify? A. Why group things? 1. easier to find information about an organism 2. easier to identify an organism 3. shows evolutionary relationships
    5. 5. I. Why Classify? A. Why group things? 1. easier to find information about an organism 2. easier to identify an organism 3. shows evolutionary relationships B. Biologists use a classification system to name organisms and group them in a logical manner
    6. 6. I. Why Classify? A. Why group things? 1. easier to find information about an organism 2. easier to identify an organism 3. shows evolutionary relationships B. Biologists use a classification system to name organisms and group them in a logical manner 1. taxonomy = scientific study of classification
    7. 7. I. Why Classify? A. Why group things? 1. easier to find information about an organism 2. easier to identify an organism 3. shows evolutionary relationships B. Biologists use a classification system to name organisms and group them in a logical manner 1. taxonomy = scientific study of classification C. binomial nomenclature = each species is assigned a two-part scientific name
    8. 8. I. Why Classify? A. Why group things? 1. easier to find information about an organism 2. easier to identify an organism 3. shows evolutionary relationships B. Biologists use a classification system to name organisms and group them in a logical manner 1. taxonomy = scientific study of classification C. binomial nomenclature = each species is assigned a two-part scientific name 1. genus = a group of closely related species, first part of the scientific name, capitalized 2. species = second part of a scientific name, lower case 3. Scientific names are always italicized or underlined A. Ex: Homo sapiens or Homo sapiens
    9. 9. II. Historical Background
    10. 10. II. Historical Background A. Aristotle - (350 B.C.E.) First scientist to group organisms as either plants or animals

    13. 13. II. Historical Background A. Aristotle - (350 B.C.E.) First scientist to group organisms as either plants or animals B. Carolus Linnaeus (1701-1778) - “Father of Modern Taxonomy” 1. grouped things according to structural similarities 2. developed a “binomial nomenclature” system for identifying every organism
