Question

question 8 of 10
which is a correct interpretation of this cladogram?
a. kangaroos evolved after earthworms.
b. earthworms are organisms that have jaws.
c. lizards were the first organisms on earth to have limbs.
d. salmon do not have segmented bodies.

Explanation:

• In a cladogram, organisms on the right - hand side (more derived) evolve after those on the left - hand side (less derived). Kangaroos are to the right of earthworms, so they evolved after earthworms.
• For option B: Earthworms are below the "Jaws" trait in the cladogram, so they do not have jaws.
• For option C: Lizards are not the first to have limbs. The cladogram shows that the trait "Limbs" is a shared trait among lizards, kangaroos, and cats, but there is no indication that lizards were the first to have this trait.
• For option D: Salmon are above the "Segmented Body" trait in the cladogram, so they have segmented bodies.

Answer:

A. Kangaroos evolved after earthworms.
