5 Matching questions

  1. Taxon
  2. Artificial classification system
  3. Species
  4. Form genus
  5. Paraphyletic group
  1. a genus based on a character that is not a reliable indicator of evolutionary relationships, unrelated groups get grouped together
  2. b a classification not based on evolutionary, phylogenetic relationships, but on other characters
  3. c : a clade that contains an ancestral taxon, and several but not all its descendants
  4. d a term that refers to any taxonomic group such as species, genus, family, etc...
    Type specimen: a single specimen that is the absolute standard for the species and its scientific name
  5. e : a group of organisms that can interbreed and produce fertile offspring

5 Multiple choice questions

  1. the binomial name of a species
  2. a trait that is shared ("symmorphy") by two or more taxa and their most recent common ancestor, whose ancestor in turn does not possess the trait.
  3. classification based on evolutionary, phylogenetic relationships
  4. during divergent evolutiona common ancstor gives rise to two or more groups, in a cladogram, it is node that gives rise to the taxa being studied
  5. 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

5 True/False questions

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


  2. Eudicotsthe clade of angiosperms that contains most species formally known as dicots, broad leaves and pollen with more than one germination pore


  3. Cladogramthe evolutionary relationships where one taxon evolves into others that evolve into still more


  4. Binomial system of nomenclatureclassification based on evolutionary, phylogenetic relationships


  5. Nomenclaturewhere a common ancestor is located on a cladogram
