Zoology

Fossils are preserved remains, impressions, or traces of organisms from the remote past, usually embedded in sedimentary rocks. Fossilization is a rare process that involves chemical and physical changes over millions of years. Different types of fossilization processes result in

The Earth’s biodiversity is not uniformly distributed. Instead, it varies geographically due to climatic, evolutionary, geological, and ecological factors. To study and understand these variations, the world is divided into distinct zoogeographical regions, each with its unique fauna (animal life).

The International Code of Zoological Nomenclature (ICZN) provides a universal set of rules and recommendations for naming animals. It ensures that every animal species has one correct and universally accepted scientific name. The ICZN promotes stability, clarity, and universality in

Taxonomic Keys: A taxonomic key is a tool used by scientists to identify organisms based on a series of choices that lead to the correct name of a given item. Keys are structured as a step-by-step process where at each

Taxonomic Procedures: Taxonomic procedures are systematic steps used by taxonomists to identify, describe, classify, and name organisms. Main Steps in Taxonomic Work: Collection of Specimens: Gathering organisms from their natural habitats for study. Observation and Recording: Detailed examination of morphological,

Speciation is the evolutionary process by which new biological species arise. It occurs when populations of the same species become genetically different enough that they can no longer interbreed successfully. Speciation leads to biodiversity — the great variety of life
