Consider the phylogeny (Fig. 34.15) below. The group Dikarya has more species than all other taxa on the tree combined. Using only the information conveyed by the labeled phylogeny below, indicate which one of the following statements is a plausible explanation as to why this is so. Select all that apply.)
A)The amount of available habitat is greater for members of the Dikarya.
B)There hasn't been enough research done on the Chytrids, so there may be many more undescribed species.
C)The evolution of hyphae allowed for rapid speciation of four of the five major groups of fungi.
D)The Dikaryotic condition provides more genetic variation and opportunities for evolution of new species.
E)Dikaryotic fungi may have lower rates of extinction than other groups of fungi.
