Similar to most amoebozoans, the forams and the radiolarians also have pseudopods, as do some of the white blood cells of animals. If one were to construct a taxon that included all organisms that have cells with pseudopods, what type of evolutionary pattern would the tree show?
A) polyphyletic
B) paraphyletic
C) monophyletic
D) it would include all eukaryotes

The tree would show a polyphyletic pattern because the trait of having pseudopods has arisen independently in different lineages (e.g., amoebozoans, forams, radiolarians, and some white blood cells in animals), rather than stemming from a common ancestor that had pseudopods and passed that trait down to all its descendants.
