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.
