Scientific classification
  • 1. Scientific classification is a hierarchical system that describes the relationships among living organisms. It involves organizing species into different levels of groups based on their shared physical characteristics and evolutionary history. The main levels of classification, from broadest to most specific, are domain, kingdom, phylum, class, order, family, genus, and species. This system helps scientists to categorize and study the immense diversity of life on Earth, providing a way to understand the evolutionary connections between different species and their place in the natural world.
