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
KINGS PLAY CHESS ON FLAT GLASS SQUARES

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
REPRESENTATIVE ORGANISMS
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’S HIERARCHY

21. CLASSIFICATION OF LIVING THINGS
LIFE’S HIERARCHY GIVES US A PLACE TO START DISCUSSING THE SPECIFICS OF HOW LIFE WORKS… SO LET’S GET TO IT!!!
