تنوع حياتي ۽ درجا بندي

Biodiversity and Classification

• Biodiversity is the variety of life on Earth. It includes all living things, from bacteria to plants to animals.
• Biodiversity is important because it provides many benefits, such as food, medicine, and resources.
• Biodiversity is threatened by human activities, such as pollution, deforestation, and climate change.
• Classification is a system of organizing living things into groups based on their characteristics.
• The aims of classification are to make identification easier, to study evolutionary relationships between organisms, and to understand the diversity of life.

Principles of Classification

• Classification principles are based on characteristics, like physical features and genetic makeup.
• Organisms are classified based on shared features and evolutionary relationships.

History of Classification

• Aristotle was an important early figure in the field of classification.
• The work of Ibn al-Jazzar contributed to the understanding of animal anatomy.
• Carolus Linnaeus's system of binomial nomenclature is still used today.

Taxonomic Hierarchy

• Organisms are organized into a hierarchy of increasingly specific groups. The main groups are generally: Kingdom, Phylum, Class, Order, Family, Genus, Species.
• Each level of the hierarchy is called a taxonomic rank, and the sequence of these ranks forms the taxonomic hierarchy.
• Each organism is assigned a unique scientific name using binomial nomenclature (two names).

Two Kingdom Classification

• In the past, organisms were broadly classified into two groups: Plants and Animals.
• Based on the presence of cells with a cell wall.

Simple Classification of Organisms

• Classifying organisms involves determining their species and the larger groups to which they belong based on similarities.
• These similarities can be anatomical or other criteria.
