Taxonomy
• Science of classifying organisms
• Provides universal name and way to iden:fy organisms
• Taxon - categories we out organisms in
Scien:sts
• 350BC - plants and animals (Aristotle)
• 1735 - Kingdoms Plantae and Animalia (Carolus Linnaeus)
• 1857 - Bacteria and Fungi put in Kingdom Plantae (Carl von Nageli)
• 1866 - Kingdom Pro:sta: Bacteria, protozoa, algae and fungi (Ernst Haeckl)
• Robert Murray - proposed kingdom Prokaryotae
• Robert WhiVaker - proposed Monera as part of 5 part kingdom system (Monera /
Pro:sta / Fungi / Animalia / Plantae)
• Carl Woese - proposed 3 domains (Eukarya / Bacteria and Archaea)
Phylogene:cs
• Grouping of organisms according to common proper:es implies that a group of
organisms evolved from a common ancestor
• Systema:cs - study of the evolu:onary history of organisms
• Hierarchy of taxa ideally reflects evolu:onary history or organisms
Classifica:on
• Nomenclature - naming of organisms
