Study Notes
Biological Classification
- The study of biological classification is known as taxonomy.
- Taxonomy involves naming, describing, and categorizing living organisms into hierarchical structures.
Grouping Organisms
- The term "phylogeny" refers to the grouping of organisms based on mutual similarity or evolutionary relatedness.
- Phylogenetic analysis helps in understanding the evolutionary history of species.
Taxonomic Hierarchy
- The first level of classification in the taxonomic hierarchy is the domain.
- Domains categorize life into three major groups: Archaea, Bacteria, and Eukarya.
Prokaryotic Strains
- In prokaryotes, strains that share stable properties and differ significantly from other groups are called "biovars."
- Biovars represent a subtype that maintains specific characteristics despite being part of a larger classification.
Ernst Haeckel's Contribution
- Ernst Haeckel depicted the concept of "Kingdoms" in his 1866 work, emphasizing the classification of life forms.
- His contributions laid foundational concepts for modern biological classification systems.
