24. History of Zoology
Aristotle (father of zoology) BC – grouped animals according to structure and conceived an evolutionary development from lower to higher, which he thought was conceived by a guiding intelligence.
Pliny the Elder, Roman, AD – Wrote the 37 volume encyclopedia Natural History.

25. History of Zoology
Galen, Greek physician, AD – Developed coherent system of physiology
Dark ages – No critical observations for over 1,000 years! Aristotle, Pliny, and Galen were the chief sources of biological information

26. History of Zoology
Renaissance – Period from 14th to 17th century began a new period of learning
Leonardo da Vinci, Italian – Famous painter, sketches animals, pioneered the field of physiology
Historia animalium – Published in 1587 by Conrad Gesner, encyclopedia consisting of 4,500 pages in 5 volumes. Based largely on the previous work of Aristotle, Pliny. The first modern work to attempt to describe all known animals.

27. Taxonomy
Carolus Linnaeus – Swedish scientist who established a universal system of classification and nomenclature with concise physical descriptions.
In 1735 published Systema naturae

28. Taxonomy Taxonomy – General to specific
Kingdom, phylum, class, order, family, genus, species
Binomial Nomenclature – Two word naming system using Genus specie
