  1. CLASSIFICATION OF LIVING THINGS

  2. CLASSIFICATION OF LIVING THINGS • ABOUT HOW MANY LIVING THINGS EXIST ON EARTH? • 1.5 MILLION KNOWN ORGANISMS • THOUSANDS MORE IDENTIFIED EACH YEAR • ABOUT 10 MILLION DIFFERENT ORGANISMS BELIEVED TO EXIST ON EARTH

  3. CLASSIFICATION OF LIVING THINGS • WITH SO MANY DIFFERENT LIVING THINGS, IT IS ESSENTIAL FOR SCIENTISTS TO ORGANIZE THEM TO MAKE IT EASIER TO SHARE, AND STUDY, INFORMATION ABOUT LIVING THINGS

  4. CLASSIFICATION OF LIVING THINGS • THE BRANCH OF BIOLOGY THAT DEALS WITH CLASSIFICATION (GROUPING) AND NAMING LIVING THINGS IS CALLED… • TAXONOMY

  5. CLASSIFICATION OF LIVING THINGS • WHY ORGANIZE??

  6. CLASSIFICATION OF LIVING THINGS • EARLY CLASSIFICATION SYSTEM

  7. CLASSIFICATION OF LIVING THINGS • MODERN CLASSIFICATION SYSTEM BASED UPON THE WORK OF CAROLUS LINNAEUS • ISN’T HE A HOTTIE?!?!?

  8. CLASSIFICATION OF LIVING THINGS • IF YOU WERE TO GROUP THINGS TOGETHER, WHAT WOULD YOU USE? • LINNAEUS GROUPED THINGS BASED ON PHYSICAL(STRUCTURAL) SIMILARITY • DIFFERENT LEVELS OF GROUPS WERE CREATED TO DEMONSTRATE VARIOUS LEVELS OF SIMILARITY

  9. CLASSIFICATION OF LIVING THINGS • TAXONOMIC CATEGORIES • KINGSPLAYCHESSONFLATGLASSSQUARES

  10. CLASSIFICATION OF LIVING THINGS

  11. CLASSIFICATION OF LIVING THINGS • A BONUS OF THIS CLASSIFICATION SYSTEM IS THAT IT LED TO A SIMPLE METHOD FOR NOMENCLATURE = “NAMING SYSTEM” • BINOMIAL NOMENCLATURE

  12. CLASSIFICATION OF LIVING THINGS • BINOMIAL NOMENCLATURE • TWO NAME NAMING SYSTEM • TWO NAMES COME FROM THE GENUS AND SPECIES GROUPS OF CLASSIFICATION • SCIENTIFIC NAME • WHY IS THIS SO IMPORTANT??

  13. CLASSIFICATION OF LIVING THINGS • WHAT MAKES LIVING THINGS THE SAME SPECIES? • SPECIES • A POPULATION OF ORGANISMS THAT IS ABLE TO REPRODUCE WITH EACH OTHER AND PRODUCE FERTILE OFFSPRING

  14. CLASSIFICATION OF LIVING THINGS • MODERN TAXONOMICAL PRINCIPLES • STRUCTURAL INFORMATION • BIOCHEMICAL INFORMATION • CYTOLOGICAL INFORMATION • EMBRYOLOGICAL INFORMATION • BEHAVIORAL INFORMATION • FOSSIL INFORMATION

  15. CLASSIFICATION OF LIVING THINGS • MAJOR TAXONOMICAL GROUPS

  16. CLASSIFICATION OF LIVING THINGS • KINGDOM – MONERA • PROKARYOTES • ARCHAEBACTERIA VS.EUBACTERIA • KINGDOM – PROTISTA • EUKARYOTE • AMEBA • PARAMECIUM • EUGLENA

  17. CLASSIFICATION OF LIVING THINGS • KINGDOM – FUNGI • EUKARYOTES • HETEROTROPH • CELL WALL • KINGDOM – PLANTS • EUKARYOTES • AUTOTROPH • CELL WALL

  18. CLASSIFICATION OF LIVING THINGS • KINGDOM – ANIMALS • EUKARYOTES • HETEROTROPH • REPRESENTATIVEORGANISMS • HYDRA • EARTHWORM • GRASSHOPPER • HUMAN

  19. CLASSIFICATION OF LIVING THINGS • WITH GROUPS MADE, SCIENTISTS USE TAXONOMIC KEYS TO CLASSIFY ORGANISMS

  20. CLASSIFICATION OF LIVING THINGS • CLASSIFICATION / GROUPING ALLOWS US TO ORGANIZE HOW WE STUDY BIOLOGY • LIFE’SHIERARCHY

  21. CLASSIFICATION OF LIVING THINGS • LIFE’S HIERARCHYGIVES US A PLACETO START DISCUSSINGTHE SPECIFICSOF HOW LIFE WORKS…SO LET’S GET TO IT!!!
