  1. The seven basic categories of biological classification. More categories are added to recognize similarities among groups of taxa within these levels, for example superfamilies, etc. Kingdom Phylum Class Order Family Genus Species

  2. An example of biological classification. Kingdom (Animalia) Phylum (Chordata) Class (Mammalia) Order (Primates) Family (Hominidae) Genus (Homo) Species (Homosapiens)

  3. Kingdom Phylum Class Order Family Genus Species

  4. Taxa show unique combinations of characteristics. For example, birds have feathers, beaks, and wings, and lay eggs, while mammals have hair, teeth, and give live birth.

  5. Patterns that exist in organisms can be explained by Evolution • Species change over time due to selection and genetic drift. • Species give rise to new species (speciation) through cladogenesis. Related species, grouped by taxa, are linked by evolutionary history. Related species share those characteristics which they inherited from their shared ancestor.

  6. Taxonomy is the classification of organisms. Most biologists feel that classification should be based upon phylogeny. Phylogenyis the ancestry of organisms- how organisms are related by evolution Systematicsis the study of phylogeny.

  7. Diagrams called cladograms are used to represent the phylogeny of organisms

  8. Cats are more similar to dogs than they are to frogs, because they share a more recent common ancestor with dogs
