List the classification of humans from kingdom to species: Dogs All are dogs the same species? Why? Similarities in DNA and RNA What relationships can be determined by comparing DNA sequences? Molecular Clocks What is the molecular clock model? What do scientists look for in the DNA sequences? Evolutionary Classification What is a cladogram Kingdoms and Domains What two kingdoms did Linnaeus recognize? List the three domains. How many kingdoms do we recognize today? What is the major difference that we use to classify organisms? What do we use to classify the “higher” kingdoms. State the ecological strategies for each of the higher kingdoms. The Five Kingdoms Fill in the chart below as we talk about the 5 kingdoms DOMAIN Bacteria Archaea Kingdom Eubacteria Archaebacteria Cell Type Cell Structure Number of Cells Mode of Nutrition Examples Other important information Eukarya Protista Fungi Plantae Animalia
