A team of researchers has developed a poison that has proven effective against lamprey larvae in freshwater cultures. The poison is ingested and causes paralysis by detaching segmental muscles from the skeletal elements. The team wants to test the poison's effectiveness in streams feeding Lake Michigan, but one critic worries about potential effects on lancelets, which are similar to lampreys in many ways. Why is this concern misplaced?
A) A chemical poisonous to lampreys could not also be toxic to organisms as ancestral as lancelets.
B) Lamprey larvae and lancelets have very different feeding mechanisms.
C) Lancelets do not have segmental muscles.
D) Lancelets live only in saltwater environments.
E) Lancelets and lamprey larvae eat different kinds of food.
