Document Summary

Animals, fungi, and related protists form the opisthokonts clade: opisthokont (common ancestor) -> nuclearlids (fungi) & choanoflagellates (animals) Animals and fungi may have diverged into separate lineages 1-1. 5 bya. Nucleariids are heterotrophic amoebas (protists: close ancestor of fungi. Fungi colonized land before plants, plants came 470 million years ago.
