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?

1. All organisms in the table share all of the derived characteristics.
2. Because it shares none of the derived characteristics, lampreys constitute an out-group.
3. Because it shares just one of the derived characteristics, sharks can be considered an internal branch of the phylogenetic tree.
4. Only humans and gorillas share all of the derived characteristics.
