The following questions refer to the information below.
A researcher compared the nucleotide sequences of a homologous gene from five different species of mammals with the homologous human gene. The sequence homology between each species' version of the gene and the human gene is presented as a percentage of similarity.
$$\begin{array} { l c }
\text { Species } & \text { Percentage } \
\hline \text { Chimpanzee } & 99.7 \
\text { Orangutan } & 98.6 \
\text { Baboon } & 97.2 \
\text { Rhesus Monkey } & 96.9 \
\text { Rabbit } & 93.7
\end{array}$$

-A phylogenetic tree constructed using sequence differences in mitochondrial DNA would be most valid for discerning the evolutionary relatedness of
A)archaeans and bacteria.
B)fungi and animals.
C)Hawaiian silverswords.
D)sharks and dolphins
E)mosses and ferns.
