Practice question
Question
Fungi are more closely related to which group based on molecular evidence?
Explanation
Molecular phylogenetics within Opisthokonta places Fungi sister to nucleariid amoebae, while Animals sister to choanoflagellates, forming two branches Holomycota and Holozoa. Nucleariids are filose amoebae lacking flagellum feeding on bacteria and algae, sharing common ancestor with fungi after divergence from Holozoa clade. Choanoflagellates possess collar flagellum more allied to animals. Green algae belong to Archaeplastida distant. Although animals also related to fungi via Opisthokont ancestry, nucleariid protists represent closest extant protistan relative to fungi based on multigene phylogenomics supporting Holomycota clade distinct from Holozoa.
