Learning Objectives

  • Identify the unique distinctive characteristics of a specific taxon relative to other taxa.

  • Recognize the importance of classifying organisms.

  • Compare how species are related based on their classification.

Activities

Activity 1: Fact vs Myth

  • Phrase: "Shaving hair makes it grow back thicker."

  • Task: Identify if it is a Fact or a Myth and write your answer on a sheet of paper.

Activity 2: Matching Activity

Discussion: Distinctive Characteristics of a Specific Taxon

Taxonomy Overview

  • Taxonomy: Science of classifying organisms to form a standardized classification system.

  • Developed by Carl Linnaeus in the 18th century.

Hierarchical Taxonomy Levels

  1. Species

  2. Genus

  3. Family

  4. Order

  5. Class

  6. Phylum

  7. Kingdom

  8. Domain

Example of Classification

  • Dog Classification:

    • Eukarya -> Animalia -> Chordata -> Mammalia -> Carnivora -> Canidae -> Canis -> lupus

    • Scientific name format: Genus (capitalized) + Species (lowercase, italicized).

Importance of Taxonomy in Biology

  • Shows relationships between living organisms.

  • Uses various fields like behavior, genetics, and fossil records for classification.

  • Facilitates communication among scientists through a universal nomenclature system.

Advances in Taxonomy

  • Carl Linnaeus: Father of taxonomy; created the binomial nomenclature system.

  • Charles Darwin: Expanded the Linnaean system to include evolutionary relationships.

  • Ernst Mayr: Emphasized evolution and speciation in taxonomic classification.
