Classification

  1. 1. Classification
  2. 2. Core concepts  Modern Taxonomy or Systematics is the field of biology that deals with organizing living things such as plants and animals into a hierarchy or category that shows artificial or natural relationships
  3. 3. Core concepts  Taxonomy or systematics involves three procedures namely classification, identification and nomenclature  Classification is a process of assigning arbitrary categories to an organism, or group/s of an organism based on its biological relatedness
  4. 4. Core concepts  Identification is a method to recognize organisms, or group/s or an organism based on its morphology, anatomy, biochemical property, molecular organization, etc. The use of traits is often subjective, but a consencus is generally made on which traits to use in identifying organisms.
  5. 5. Core concepts  Nomenclature is simply the practice of naming organisms based on rules of certain codes for every taxa of organism. The ICBN (International Code for Botanical Nomenclature) has rules for naming and publishing plant specimens that are new to science. The counterpart of ICBN is the ICZN (International Code for Zoological Nomenclature), while in microorganisms it is the International Code for Naming Bacteria.
  6. 6. Keywords  Taxonomy systematics classification  Identification nomenclature hierarchy  Category artificial natural  Taxon species binomial system  Linnean classification domain kingdom  Division/phylum class order family genus  Specific epithet archaea bacteria eukarya protista mycetae/fungi plantae animalia
  7. 7. Classification  Evolutionary systematics  Phenetic systematics  Cladistic systematics
  8. 8. Evolutionary systematics  Use of phylogenetic relationship and over all similarity of organisms  Taxa > single species  Groups of species give rise to new groups
  9. 9. Evolutionary systematics  Pre-Darwinian Linnean taxonomy- orderly lists  Evolutionary systematics- phylogenetic trees  Allows for paraphylectic trees  Use of dinosaurs to links extinct and extant species  Monophylectic  Paraphylectic  polyphylectic
  10. 10. mammalia synapsida amniota reptilia dinosauria crocodilia aves
  11. 11. Phenetic systematics  Also known as taximetrics  Method of clasification that uses morphology or other observable traits regardless of any phylogentic or evolutionary relationship
  12. 12. Cladistic systematics  Method of classifying organisms based on groups or clades  Clades- ancestor and all descendants  Single branch on the tree of life, monophylectic  Plesiomorphies- derived characteristics from ancestors  Apomorphies- evolved traits  Synapomorphies- shared traits
  13. 13.  Evolutionary taxonomist- birds evolved from dinosaurs  Cladist- birds are dinosaurs
  14. 14. Linnean species vs Darwinian species  Immutable species  Mutable species
  15. 15. Good taxonomic system should be…..  Universally accepted  Classification of organisms should have real biological meaning
  16. 16. Scheming scientists….  2 kingdom scheme  4 kingdom scheme  5 kingdom scheme  6 kingdom scheme  3 domain scheme

  19. 19. 4 + 4 bagong bapor  Herbert Copeland due to electron microscope  Ability to discern organelles  Monera  Protista  Plantae  Animalia  Presence of superkingdom- empire prokaryota, empire eukaryota

  23. 23. Group Assignment  Short history of taxonomy  Hunter gatherer period  Sedentary lifestyle  Agricultural period  Greeks to Karolus Linnaeus  Modern taxonomy and systematics  How do species arise?  Biological species concept (BSC)- advantages and disadvantages over other species concept
