5 Matching questions

  1. Basal angiosperms
  2. Phylogeny
  3. Taxon
  4. Homologous features
  5. Apomorphy
  1. a the several clades of angiosperms that arose before the rest of the angiosperms diverged into the monocots and eudicots
  2. b the evolutionary relationships where one taxon evolves into others that evolve into still more
  3. c a feature present in one (autopomorphy) or several (synopomorphy) derived members of a group but is not present in the ancestral members
  4. d features that are the phenotypic expression of homologous genes, those related by descent from common ancestoral genes
  5. e 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 Multiple choice questions

  1. genus based on a character that is not a reliable indicator of evolutionary relationships, unrelated groups get grouped together
  2. a branching diagram sowing the phylogenetic relationships of several or many taxa
  3. the binomial name of a species
  4. 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.
  5. where a common ancestor is located on a cladogram

5 True/False questions

  1. Paraphyletic group: a clade that contains an ancestral taxon, and several but not all its descendants


  2. Natural system of classification: a system providing scientific names to organisms, each name consists of the genous name and the speciec epithet


  3. Common ancestorduring 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


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


  5. Eudicots: a group of organisms that can interbreed and produce fertile offspring
