Question

Which system of grouping is in figure 18-2, A or B provides information about the evolution of the three animals

Answer 1

Figure B is the answer

Answer 2

Answer:

B

Explanation:

You have three stages for analyzing.

You start at B with a tiny free-swimming larva.

Some of those larvas start making segmentation. It is an evolutionary trait.

This divide what we today know as gastropods and those animals that continue with evolution.

Those segmentation larvas also evolve with a molten external skeleton which made them all crustaceans as we know them today.

Crab and barnacle are differentiation into the crustaceans.
