1 Q.Q. 2/11/19 a) Working with your partner, organize Legos into groups, creating your own categories. There is not a RIGHT or WRONG way to group them- you choose! b) Write your categories in your notebook and draw a picture of your Lego groupings. Example: copyright cmassengale

2 Organizing and Classifying the Diversity of Organisms

3 copyright cmassengale
Species of Organisms There are 13 billion known species of organisms This is only 5% of all organisms that ever lived!!!!! New organisms are still being found and identified copyright cmassengale

4 copyright cmassengale

5 What is Classification?
Classification is the arrangement of organisms into orderly groups based on their similarities Classification is also known as taxonomy Taxonomists are scientists that identify & name organisms copyright cmassengale

6 copyright cmassengale
Homologous Structures (BONES in the FORELIMBS) shows Similarities in mammals. copyright cmassengale

7 Similarities in Vertebrate Embryos
copyright cmassengale

8 Benefits of Classifying
Accurately & uniformly names organisms Prevents misnomers such as starfish & jellyfish that aren't really “fish” Uses same language (Latin or some Greek) for all names Sea”horse”?? copyright cmassengale

9 Confusion in Using Different Languages for Names
copyright cmassengale 9 9

10 Latin Names are Understood by all Taxonomists
copyright cmassengale 10 10

11 copyright cmassengale
Early Taxonomists 2000 years ago, Aristotle was the first taxonomist Aristotle divided organisms into plants & animals He subdivided them by their habitat –land, sea, or air dwellers copyright cmassengale

12 copyright cmassengale
Carolus Linnaeus 1707 – 1778 Called the “Father of Taxonomy” Developed the naming system still used today: Binomial nomenclature Two-word name (Genus & species) Classified organisms by their structure copyright cmassengale

13 Standardized Naming- Binomial Nomenclature
Turdus migratorius Genus species Latin or Greek Italicized in print Capitalize genus, but NOT species Underline when writing American Robin copyright cmassengale

14 Binomial Nomenclature
Which TWO are more closely related? copyright cmassengale

15 Rules for Naming Organisms
The International Code for Binomial Nomenclature contains the rules for naming organisms All names must be approved by International Naming Congresses (International Zoological Congress) This prevents duplicated names copyright cmassengale

16 Classification Groups
Taxon ( taxa-plural) is a category into which organisms are placed based on evolutionary relationships. There is a hierarchy of groups (taxa) from broadest to most specific Domain, Kingdom, Phylum, Class, Order, Family, Genus, species copyright cmassengale

17 Hierarchy-Taxonomic Groups
Domain Kingdom Phylum Class Order Family Genus Species BROADEST TAXON Genus and species are the two names used to identify specific organisms in the binomial system of classification. Division is used for plants. Most Specific copyright cmassengale

21 Dear King Philip Came Over From Germany Saturday *To HELP you
Remember: TAXONOMY OF SPECIES Smallest grouping Largest group Dear King Philip Came Over From Germany Saturday S G F O C P K D

22 copyright cmassengale
Domains Broadest, most inclusive taxon Three domains: Archaea - unicellular prokaryotes Bacteria - unicellular prokaryotes (NO nucleus or membrane-bound organelles) Eukarya - more complex WITH a nucleus and membrane-bound organelles copyright cmassengale

23 3 Domains of Life

24 copyright cmassengale
ARCHAEA Kingdom= Archaebacteria Probably the 1st cells to evolve Live in HARSH, EXTREME environments Found in: Sewage Treatment Plants Thermal or Volcanic Vents Hot Springs or Geysers that are acid Very salty water (Dead Sea; Great Salt Lake) copyright cmassengale

25 copyright cmassengale
ARCHAEAN copyright cmassengale

26 copyright cmassengale
BACTERIA Kingdom= Eubacteria Most common; some may cause DISEASE Found in ALL HABITATS except harsh ones Important decomposers for environment Commercially important in making cottage cheese, yogurt, buttermilk, etc. copyright cmassengale

27 Live in the intestines of animals copyright cmassengale

28 Domain Eukarya is Divided into FOUR Kingdoms
Protista Fungi Plantae Animalia copyright cmassengale

29 copyright cmassengale
Protista Most are unicellular Some are multicellular Some are autotrophic, while others are heterotrophic Aquatic Algae, seaweed copyright cmassengale

30 copyright cmassengale
Fungi Multicellular, except yeast Absorptive heterotrophs (digest food outside their body & then absorb it) Cell walls made of chitin copyright cmassengale

31 copyright cmassengale
Plantae Multicellular Autotrophic Absorb sunlight to make glucose – Photosynthesis Cell walls made of cellulose Growth, with increases in size and number of cells, is part of development. Development involves many stages from conception until death. copyright cmassengale

32 copyright cmassengale
Animalia Multicellular Ingestive heterotrophs (consume food & digest it inside their bodies) Feed on plants or animals copyright cmassengale

33 QUESTION #1: Two worms in the same class must also be grouped in the same Order Phylum Genus Family Species

34 QUESTION #1: Two worms in the same class must also be grouped in the same Order Phylum Genus Family Species

35 QUESTION #2: Which of the following is the most inclusive Order Genus
Kingdom Species Domain

36 QUESTION #2: Which of the following is the most inclusive Order Genus
Kingdom Species Domain

37 QUESTION #3: Which of the following is the most exclusive Order Genus

Cladograms Diagram showing how organisms are related based on shared, derived characteristics such as feathers, hair, or scales *on main branch Organizes groups of organisms by common evolutionary ancestry *WRITE: Outgroup- group of organisms that do NOT share the derived character copyright cmassengale

45 HUMAN EVOLUTION Earliest hominid fossils found in East Africa
6-7 Million years ago

46 Lucy Tree climbing, also discuss big toe position Human and Chimp

47 Human chromosome 2 and its homologues in chimpanzees & gorillas
Figure 20.7 Human chromosome 2 and its homologues in chimpanzees and gorillas The banding patterns on stained chromosomes reveal that human chromosome 2 is derived from the fusion of two chromosomes that remain separate in the other great apes. From Hacia (2001).

48 Features that differ between humans and apes
Bipedalism Skull size -> Brain size Position of skull on spine -> foramen magnum Pelvis size Teeth

49 Timing divergence from the molecular clock and fossils
Figure 20.6 Divergence times for the apes Stauffer and colleagues estimated the dates of the common ancestors on this phylogeny by combining data from dozens of proteins used as molecular clocks. The heavy bars show +/- 1 standard error around the time estimates; the lighter bars show 95% confidence intervals. From Stauffer et al. (2001).
