1. What is biological classification?Biological classification is the science of grouping all living things on Earth into organized categories. It helps scientists see how different species are related and how they live in nature.
2. Why do scientists use a hierarchy like Domain, Kingdom, etc.?The hierarchy starts with broad groups and narrows down to specific ones. This lets scientists compare many organisms at once and then look closely at the ones that are very similar.

Phylogenetics: The study of evolutionary relationships among biological entities, often depicted in tree-like diagrams.
Cladistics: A method of classification that groups organisms based on shared derived characteristics inherited from a common ancestor.
Monophyletic Group: A group of organisms that includes a common ancestor and all of its descendants.
