Study Notes
Scientific Naming of Organisms
- Each organism is assigned a unique scientific name, ensuring global recognition and consistency.
- The naming convention consists of two main parts: the Generic name and the Specific epithet, known as Binomial nomenclature.
- This system was developed by Carolus Linnaeus and is widely adopted in biology.
Binomial Nomenclature
- An example of Binomial nomenclature is Mangifera indica (mango), where Mangifera is the genus and indica is the specific epithet.
- Scientific names are generally in Latin, regardless of their origin, and are written in italics.
- Handwritten names require underlining both components, with the genus name starting with a capital letter and the specific epithet in lowercase.
Author Citation
- The author's name is abbreviated and placed after the specific epithet, e.g., Mangifera indica Linn.
Biodiversity
- Approximately 1.7 to 1.8 million species have been identified globally, reflecting Earth's rich biodiversity.
- New species continue to be discovered as areas are explored.
Importance of Nomenclature
- Standardizing names is essential to avoid confusion posed by local names which vary by region.
- Naming is only effective when organisms are accurately identified and described.
Classification and Taxonomy
- Classification organizes living organisms into convenient categories based on observable traits, known as taxa.
- Examples of taxa include terms like "plants," "animals," "mammals," etc., which signify different levels of classification (e.g., "dogs" as a subset of "mammals").
- Taxonomy includes processes of characterization, identification, classification, and nomenclature as essential components of studying organisms.
Taxonomy Framework
- Scientific rules for plant naming are established under the International Code for Botanical Nomenclature (ICBN).
- Animal naming follows the International Code of Zoological Nomenclature (ICZN).
- Both codes ensure that species are accurately described and classified.
Basis of Taxonomic Studies
- Taxonomic studies rely on external and internal structures, cellular organization, developmental processes, and ecological data.
- The disciplines of characterization, identification, classification, and nomenclature form the foundation of taxonomy, which is vital for understanding biological diversity.
