  1. Classification

  2. Aristotle 384 BC Classified organisms as either plants or animals

  3. Carolus Linnaeus 1707-1778 Classification system Taxonomic groups of related organisms Binomial nomenclature (two names) Genus and species named using Latin or Greek words

  4. Binomial Nomenclature • An organism’s genus is always written first; the organism’s species is always written second • The genus is Capitalized; the species is written in lower case • Scientific names of organisms are always italicized or underlined • Ex: Homo sapiens

  5. The scientific name also tells you which species are similar • • Which of these three species are similar: • o Erithacusjohnstoniae • o Turdusmigratorius • o Erithacusrubecula

  6. If you selected Erithacusjohnstoniae and Erithacusrubecula, you are correct! Erithacusjohnstoniae and Erithacusrubecula share the same genus – Erithacus.

  7. The modern system of classification has 8 levels: Domain Kingdom Phylum Class Order Family Genus Species

  8. Pneumonic device Dear Domain King Kingdom Phillip Phylum Came Class Over Order For Family Good Genus Spaghetti Species

  9. Classification of Man Kingdom Animalia PhylumChordata Class Mammalia Order Primates Family Hominidae Genus Homo Species Homosapiens

  10. Classification goes from the broadest to the most specific

  11. Phylum In the kingdom Animalia over there are over 41 different phyla We will be discussing around 21 of them

  12. Class Class comes between phylum and order As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the prefix sub-: subclass Each phylum can have between 1-8 classes in it

  13. There are definitions of the following taxonomic ranks in the International Code of Zoological Nomenclature: superfamily, family, subfamily, tribe, subtribe, genus, subgenus, species, subspecies.

  14. Starting from the most specific we have species. A genus contains the species A family contains the genera. Similar genera are grouped together

  15. Similar families are combined into an order. Orders with common properties are united in a class. Classes with similar characteristics are assigned to a phylum. Similar phyla are collected into a kingdom. Similar kingdoms are grouped into domains.

  16. Cladogram Evolutionary relationship of a group of organisms Each clad (group) share something in common Ancestral traits are the oldest Derived traits evolved later
