For the data table shown above, a 1 indicated that the trait is present and a 0 indicates that the trait is absent.

Which of the following statements represents an accurate interpretation of the data?

A

All organisms in the table share all of the derived characteristics.

B

Only humans and gorillas share all of the derived characteristics.

C

Because they share none of the derived characteristics, lampreys constitute an out-group.

D

Because they share just one of the derived characteristics, sharks can be considered an internal branch of the phylogenetic tree.
