Which group of Eukarya has complicated the phylogenetics of the domain by first being thought of as ancient to the more recent view of them being highly derived eukaryotes?
A) dinoflagellates
B) fungi
C) hydrogenosome-containing eukaryotes
D) stramenopiles

Question

Quizplus · Accepted Answer

Hydrogenosome-containing eukaryotes, such as parabasalids, were once thought to be ancient eukaryotes due to their lack of conventional mitochondria. However, recent molecular and genomic studies have suggested that they are highly derived and possibly secondarily adapted to a hydrogen-producing lifestyle. This has complicated the phylogenetics of the domain Eukarya.
