Researchers discovered a new species complex of butterflies on an archipelago of islands in the Pacific Ocean. Each island has a unique species that has evolved to make use of the host plants available on a particular island. They conducted a phylogenetic analysis using a barcoding gene to reconstruct the origin and colonisation history of these butterflies. The phylogenetic tree is depicted below: Navorsers het 'n nuwe skoenlapper spesie-kompleks op ʼn argipel van eilande in die Stille Oseaan ontdek. Elke eiland het 'n unieke spesie wat ontwikkel het om gebruik te maak van die gasheerplante wat op 'n spesifieke eiland beskikbaar is. Hulle het 'n filogenetiese analise gedoen met behulp van 'n strepieskode-geen om die oorsprong en kolonisasiegeskiedenis van hierdie skoenlappers te rekonstrueer. Die filogenetiese boom word hieronder uitgebeeld Japan Island C Island D Island B Island A China
Regarding the phylogenetic tree: Met betrekking tot die filogenetiese boom: Select one: a. It is an unrooted tree, as it does not encapsulate an actual (extinct or extant) common ancestor for all of the terminal taxa Dit is hongewortelde boom, omdat dit nie h werklike (uitgestorwe of lewendige) gemene voorouer vervat vir al die terminale taksa nie b. It is a rooted tree, as it encapsulates a hypothetical common ancestor for all of the terminal taxa Dit is h gewortelde boom, omdat dit h hipotetiese gemene voorouer vervat vir al die terminale taksa c. It is a rooted tree, as it does not encapsulate a hypothetical common ancestor for all of the terminal taxa Dit is n gewortelde boom, omdat dit nie h hipotetiese gemene voorouer vervat vir al die terminale taksa nie d. It is an unrooted tree, as it does not encapsulate a hypothetical common ancestor for all of the terminal taxa Dit is ʼn ongewortelde boom, omdat dit nie h hipotetiese gemene voorouer vervat vir al die terminale taksa nie e. It is an unrooted tree, as it encapsulates an actual (extinct or extant) common ancestor for all of the terminal taxa Dit is ʼn ongewortelde boom, omdat dit ʼn werklike (uitgestorwe of lewendige) gemene voorouer vervat vir al die terminale taksa f. It is an unrooted tree, as it encapsulates a hypothetical common ancestor for all of the terminal taxa Dit is hongewortelde boom, omdat dit h hipotetiese gemene voorouer vervat vir al die terminale taksa g. It is a rooted tree, as it does not encapsulate an actual (extinct or extant) common ancestor for all of the terminal taxa Dit is h gewartelde boom, omdat dit nie h werklike (uitgestorwe of lewendige) gemene voorouer vervat vir al die terminale taksa nie h. It is a rooted tree, as it encapsulates an actual (extinct or extant) common ancestor for all of the terminal taxa Dit is ʼn gewortelde boom, omdat dit in werklike (uitgestorwe of lewendige) gemene voorouer vervat vir al die terminale taksa
Regarding the internal node marked with a "red X" on the figure: Met betrekking tot die interne node gemerk met ʼn "rool X" op die figuur: a. The extant common ancestor for all of the island species. Die lewende gemene voorouer vir al die eiland spesies. b. The extinct common ancestor for species A, B and D. Die uitgestorwe gemene voorouer vir spesies A, B en D. c. The hypothetical common ancestor for species A, B and D. Die hipotetiese gemene voorouer vir spesies A B en D. d. The hypothetical common ancestor for all of the island species. Die hipotetiese gemene voorouer vir al die eiland spesies e. The extinct common ancestor for all of the island species. Die uitgestorwe gemene voorouer vir al die eiland spesies. f. That the species on island C is the common ancestor to all island species. Dat die spesie op eiland C die gemene voorouer is vir al die eiland spesies g. That the species on island D is the common ancestor to species A and B. Dat die spesie op eiland D die gemene voorouer is vir spesies A en B.
