the diagram below shows fossils in three layers of rocks.
which of these conclusions is most likely correct about the organisms found in the layers of rocks? (4 points)
the organism in layer a is more complex than the organism in layer b.
the organism in layer b is more complex than the organism in layer c.
the organism in layer c is a modern form of the organism in layer b.
the organism in layer a is a modern form of the organism in layer b

Explanation:

In geological and biological terms (related to fossil layers), the principle of superposition states that older layers are at the bottom (Layer A is oldest, then B, then C as youngest). Evolutionarily, younger fossils (in upper layers) often show more modern/evolved forms from older (lower) ones.

• Option 1: Layer A is older than B, so A should be less complex than B (incorrect).
• Option 2: Layer B is older than C, so B should be less complex than C (incorrect).
• Option 3: Layer C is younger than B, so C can be a modern form of B (consistent with evolution and superposition).
• Option 4: Layer A is older than B, so A can’t be a modern form of B (incorrect).

Answer:

C. The organism in Layer C is a modern form of the organism in Layer B
