Study Notes
Concept of Micro Taxonomy
- The concept of micro taxonomy was proposed by Ernst Mayr.
Word Variety and Evolutionary Systematics
- The Word "variety" was coined by Bailey.
- Evolutionary systematics is also called as phylogenetic systematics.
Phylogenetic Theory and Traditional Theory
- Phylogenetic theory only accepts monophyletic groups.
- Traditional theory concept accepts paraphyletic and polyphyletic groups.
Species Concept
- A group of potentially or actually interbreeding natural population which is reproductively isolated from other such groups are called biological species.
- A reproductive community of sexually reproducing individuals which share in a common gene pool and is widely accepted are called biological species.
Evolutionary Species Concept
- Evolutionary species concept was proposed by Simpson.
Mental Concept
- Typological species concept are called mental concept.
Polytypic Species
- Species which contain two or more than two subspecies, are called polytypic species.
International Code of Zoological Nomenclature (ICZN)
- The ICZN has since released several editions of the International Code of Zoological Nomenclature, which provides guidelines and rules for naming and classifying animals.
- Objectives of the ICZN and its codes include:
- Providing a system for naming and classifying animals that is stable, predictable, and widely accepted by the scientific community.
- Ensuring that animal names are unique, unambiguous, and correctly spelled and formatted.
- Providing rules for resolving conflicts or inconsistencies in animal names.
- Promoting the use of scientific names in all publications and communications related to zoology.
- Encouraging the publication of new taxonomic descriptions in peer-reviewed scientific journals.
- Facilitating communication and collaboration among zoologists around the world by promoting the use of a common language for naming animals.
Principles of Zoological Nomenclature
- Binomial nomenclature: Each species is assigned a two-part name consisting of a genus name and a specific epithet (e.g., Homo sapiens).
- Priority: The first valid publication of a name takes precedence over subsequent publications, even if they are more recent or more widely used.
- Conservation: Names should not be changed unnecessarily or arbitrarily.
- Availability: Names should be available for use by other scientists.
- Zoological Code: All names should conform to the rules established by the ICZN in its Code.
- Diagnosis: Each new taxonomic description should include a clear diagnosis that distinguishes the new taxon from other similar taxa.
- Type specimens: Each new taxonomic description should designate a type specimen, which is a representative individual that serves as a reference for the species.
History of Zoological Nomenclature
- The history of Zoological Nomenclature can be traced back to ancient times when humans first started documenting and classifying animals.
- In 1758, Swedish naturalist Carl Linnaeus published his work "Systema Naturae," which introduced the binomial nomenclature system that is still in use today.
- The first formal rules for zoological nomenclature were established in 1842 by the French zoologist Georges Cuvier.
- The International Commission on Zoological Nomenclature (ICZN) was established in 1895 as the international authority responsible for regulating animal names.
