What is classification and why is classification important? • Classification puts things into groups. • It makes things easier to find, identify, and study.
What is scientific classification? • Group organisms based on common traits and adaptations
How do scientists classify organisms? • Group first into: • Kingdoms (the largest) • Phylum • Class • Order • Family • Genus (first part of scientific name) • Species (second part of scientific name) • Use binomial nomenclature (two-parted names) to identify species
