If you were to create an evolutionary tree in which amoebas were included within the kingdom of organisms to which they were the most closely related (rather than with protists, where they are currently placed), where would you put them?

Certain protists species cause human disease that are difficult to treat and are often deadly. How does the evolutionary relatedness of humans and protists explain the difficultly of treating a person infected with a pathogenic protist?

- DNA sequence data for a diplomonad, a euglenid, a plant, and an unidentified protist suggest that the unidentified species is most closely related to the diplomonad. Further studies reveal that the unknown species has fully functional mitochondria. Based on these data, at what point on the phylogenetic tree in Figure 1 did the mystery protist’s lineage probably diverge from other eukaryote lineages? Explain.arrow_forwardSome molecular evidence suggests that the sister group of animals is not the choanoflagellates, but rather a group of parasitic protists, Mesomycetozoa. Given that these parasites lack collar cells, can this hypothesis be correct? Explain.arrow_forwardAmoeba, Paramecuim, and Spirogyra are diverse.
