Quizplus · Accepted Answer

The group of hydrogenosome-containing eukaryotes, which includes organisms such as Giardia and Trichomonas, were initially thought to be very ancient and primitive eukaryotes. However, more recent research has shown that they are highly derived and have lost many ancestral features, leading to their complicated phylogenetics.
