- Cladistics is the dominant method for classifying life, based on shared ancestry and all descendants.
- Humans belong to multiple nested clades, such as hominins (bipedal, large-brained), apes, primates, and mammals.
- Key clades include eukaryotes (organisms with a cell nucleus), animals (multicellular, motile), and vertebrates (with a spinal column).
- The classification system illustrates evolutionary relationships, extending from specific groups like hominins to broad categories like life itself.
- Cladistics represents a recent paradigm shift in biology, influenced by advances in genetic sequencing since the 1990s.
- Each clade has distinctive features and includes organisms not found in more specific clades, such as plants in diphods or fungi in opisthokonts.
