Question

what is the value of a transitional fossil?
transitional forms are proof of punctuated equilibrium in evolution.
transitional forms are analogous fossils.
transitional forms discredit the theory of evolution.
transitional forms show the evolutionary steps between species.

Explanation:

• Analyze each option:
• Option 1: Punctuated equilibrium is about rapid bursts of evolution, transitional fossils show gradual change (not proof of punctuated equilibrium), so incorrect.
• Option 2: Analogous fossils have similar functions but different origins; transitional fossils show evolutionary links (not analogous), so incorrect.
• Option 3: Transitional fossils support evolution (don't discredit it), so incorrect.
• Option 4: Transitional fossils (like Archaeopteryx) show intermediate forms between species, illustrating evolutionary steps.

Answer:

D. Transitional forms show the evolutionary steps between species.
