-Biologist use similarities in body structures, breeding behaivor, geographical distribution, chromosomes, and biochemistry to determine evolutionary relationships-

-Modern classification systems are based on phylongeny.  Both cladograms and the fanlike model include information about phlogeny-

-Taxonomists organize organisms into six kingdoms.  Kingdom Archea and Eubacteria contain only unicellular prokaryotes that differ chemicall from each other.  Kingdom Protista contains eukaryotes that lack complex organ systems.  Kingdom Fungi includes heterotrophic  eukaryotes that absorb nutrients.  Kingdom Plantea include multicellular eukaryotes that are photosynthetic.  Kingdom Animalia includes multicellular, eukaryotic heterotrophs with cells that lack cell walls-
