Question 2: The difference between paraphyletic and polyphlectic groups is: A. Paraphyletic groupings are based on shared derived characteristics, but polyphyletic groups are notB. Paraphyletic groups are made up of taxa with shared, ancestral characteristicsC. Polyphyletic groups include taxa with traits that evolved independently and the common ancestor is not included in the groupD. Both A and C are correctE. Both B and C are correct
50) Some protists, formerly united as the ʺamitochondriateʺ clade, have recently been shown to be rather diverse. Some of them possess neither mitochondria nor mitochondrial genes (and have been classified as fungi). Others possess no mitochondria, but do have mitochondrial genes in their nuclear genome. Still others have modified mitochondria (viz. mitosomes or hydrogenosomes). Which statement(s) represent(s) consequences of these recent findings? 1. The amitochondriates do not comprise a true clade. 2. The ʺamitochondriate hypothesisʺ concerning the root of the eukaryotic tree has been strengthened. 3. Just as there is a diversity of cyanobacterial descendants among eukaryotes, so too is there a diversity of alpha-proteobacterial descendants among the eukaryotes. 4. If the amitochondriate organisms continued to be recognized as a taxon, this taxon would be polyphyletic. 5. Horizontal gene transfer involving mitochondrial genes has occurred in some amitochondriate organisms. A) 1 only…
