Study Notes
Introduction to the Living World
- Living organisms exhibit a remarkable diversity across various habitats including mountains, forests, oceans, lakes, deserts, and hot springs.
- The beauty and dynamics of life, such as galloping horses and migrating birds, inspire wonder and reflection on the essence of life.
Understanding Biodiversity
- The variety of life includes visible organisms like plants, insects, and animals, as well as numerous microscopic entities.
- Biodiversity encompasses approximately 1.7 to 1.8 million known species, highlighting the vast array of life on Earth.
- Discovery of new species continues as exploration of both new and familiar areas progresses.
Importance of Nomenclature
- Local names for organisms vary significantly, creating potential confusion in communication about species.
- Nomenclature standardizes organism names globally, ensuring clarity and uniformity.
- Scientific naming relies on accurate identification, allowing distinct organisms to be assigned unique names.
Naming Conventions
- The International Code for Botanical Nomenclature (ICBN) governs plant naming, while the International Code of Zoological Nomenclature (ICZN) is used for animals.
- A scientific name comprises two parts: the genus (Generic name) and the specific epithet, known as Binomial nomenclature.
- Example: The scientific name for mango is Mangifera indica, where "Mangifera" identifies the genus and "indica" denotes the specific species.
Rules of Nomenclature
- Biological names are typically derived from Latin and are presented in italics.
- The first word indicates the genus, while the second specifies the species.
- When handwritten, both components of a name are underlined to denote their Latin origins.
Essential Principles of Binomial Nomenclature
- The naming system established by Carolus Linnaeus is universally accepted among biologists.
- Ensures that each organism has a unique name, avoiding duplication across different species.
- The systematic naming enables biologists globally to consistently denote living organisms, facilitating research and communication in the biological sciences.
