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

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
classification of living things3
CLASSIFICATION OF LIVING THINGS
  • THE BRANCH OF BIOLOGY THAT DEALS WITH CLASSIFICATION (GROUPING) AND NAMING LIVING THINGS IS CALLED…
  • TAXONOMY

CLASSIFICATION OF LIVING THINGS
  • EARLY CLASSIFICATION SYSTEM
classification of living things6
CLASSIFICATION OF LIVING THINGS
  • MODERN CLASSIFICATION SYSTEM BASED UPON THE WORK OF CAROLUS LINNAEUS
  • ISN’T HE A HOTTIE?!?!?

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

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

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??

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
