2. Fungi
 Fungi is thought to have originated from a flagellated
ancestor eventhough most fungi do not have flagella, the
earliest lineages of fungi do contain flagella. Also DNA
sequence data suggests that eukaryotes like
fungi, animals, and protistan all form a clad called
opisthokonts, which is defined as having the flagellum on a
posterior location. DNA sequence data also suggests that
fungi are closely realted to several groups of single-celled
protists, which indicates that their ancestor was unicellular.
Scientists believe that the ancestors of fungi diverged into
separate lineages about one billion years ago, but the
oldest undisputed fossils of fungi are obly about 460 million
years old. The lineage of fungi is still currently the subject
of much research.
