Document Summary

Homologous linneaus classified organisms based on morphologically and structurally similar characters rather than differences, this term refers to these type of characters. Common every animal in a taxon shares this type of ancestor. Italic special text formatting that you have to apply to a genus species name when typed. Derived in some animals in a taxon the original characters that defined the group have been modified, they are now this type of characters. Synamorphies these derived characters are shared by all members of the clade and are referred to as these. Monophyletic cladistics emphasizes this type of relationship between the different taxa. Taxon a term that describes any of the major or minor groups in the classification system. Fungi the kingdom of multicelled saprophytic organisms that have a cell wall composed of chitin. One monophyletic groups have this number of ancestors. Wings these appendages of bats and birds are homologous with our arms.
