A new species of aquatic chordate is discovered that resembles an ancient form. It has the following characteristics: external armor of bony plates, paired lateral fins, and a bony skeleton. In addition to these, it will probably have which of the following characteristics? a) legs
b) metamorphosis
c) an amniotic egg
d) no jaws

a) legs

Explanation:

Based on these characteristics it can also be said that this species would have legs. This is due to this new species having paired lateral fins. That is because paired lateral fins refer to the pectoral and ventral fins, which are corresponding to the fore and hind legs of the higher animals. Meaning that this new species would have had to have legs if they had paired lateral fins, and a bony skeleton would help corroborate this finding.
