5 Matching questions

  1. Species
  2. Form genus
  3. Common ancestor
  4. Analogous features
  5. Homologous features
  1. a genus based on a character that is not a reliable indicator of evolutionary relationships, unrelated groups get grouped together
  2. b features that are the phenotypic expression of homologous genes, those related by descent from common ancestoral genes
  3. c features that resemb;e eachother but are not based on homologous genes, those related by descent from common ancestral genes
  4. d : a group of organisms that can interbreed and produce fertile offspring
  5. e 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 Multiple choice questions

  1. 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
  2. the clade of angiosperms that contains most species formally known as dicots, broad leaves and pollen with more than one germination pore
  3. where a common ancestor is located on a cladogram
  4. 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. : a system providing scientific names to organisms, each name consists of the genous name and the speciec epithet

5 True/False questions

  1. Paraphyletic groupthe evolutionary relationships where one taxon evolves into others that evolve into still more

          

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

          

  3. Inheritance of acquired characteristicsthe first law of mendelian genetics

          

  4. Phylogenythe 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. Taxonthe 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
