Taxonomy & Binomial Nomenclature Taxonomy is the science of naming and classifying organisms 14 September 2021
Binomial Nomenclature n n Binomial Nomenclature= The two names are the genus and the species Uses a standardized format n n Genus- capitalized, species- all lowercase Either italicized or underlined An International Commission controls and okay's new names Felis domesticus or Canis familiaris 14 September 2021

For example: Subclass or Superorder
Seven Major Groupings As with Aristotle, groupings are still based on similarities. n The types of similarities are much more standardized: n Structural n Biochemical n Chromosomal (DNA) similarities n 14 September 2021
Definitions n Biological species n n A group of similar organisms capable of interbreeding and producing fertile offspring. This is a limited definition with several notable exceptions n wolf/dog, wheat/rye, some fish 14 September 2021
What is Zoology? n Our study will consist of n Viruses and Bacteria n Protists n Sponges n Cnidarians/Coelenterates (jellyfish, anemones) n Worms (flat, round, and segmented) n Molluscs (clams, snails, octopus) n Echinoderms (sea stars) n Arthropods (spiders, insects) n Fish n Amphibians n Reptiles n Birds n Mammals 14 September 2021
