  1. a : a clade that contains an ancestral taxon, and several but not all its descendants
  2. b the binomial name of a species
  3. c the evolutionary relationships where one taxon evolves into others that evolve into still more
  4. d a trait which is shared (a symmorphy) between two or more taxa, but which is also shared with other taxa which have an earlier last common ancestor with the taxa under consideration
  5. e where a common ancestor is located on a cladogram

5 Multiple Choice Questions

  1. genus based on a character that is not a reliable indicator of evolutionary relationships, unrelated groups get grouped together
  2. the concept of minimum complexity: the simplest hypothesis that explains several observation is the most parsimonious. In cladistics, a cladogram with the least number of steps is the most parsimonious
  3. the clade of angiosperms that contains most species formally known as dicots, broad leaves and pollen with more than one germination pore
  4. a feature present in one (autopomorphy) or several (synopomorphy) derived members of a group but is not present in the ancestral members
  5. classification based on evolutionary, phylogenetic relationships

5 True/False Questions

  1. Basal angiospermsthe several clades of angiosperms that arose before the rest of the angiosperms diverged into the monocots and eudicots


  2. Homologous featuresfeatures that resemb;e eachother but are not based on homologous genes, those related by descent from common ancestral genes


  3. Binomial system of nomenclature: a system providing scientific names to organisms, each name consists of the genous name and the speciec epithet


  4. Analogous featuresfeatures that are the phenotypic expression of homologous genes, those related by descent from common ancestoral genes


  5. Inheritance of acquired characteristicsthe first law of mendelian genetics
