If there is no direct measurement comparing fossil-rate changes to modern populations, which interpretation is supported by the material?

• A. It cannot inform about modern populations at all.
• B. The rate observed in the fossil record must apply to modern populations.
• C. It is possible that the same rate of change observed in the fossil record applies to modern populations.
• D. Modern populations will necessarily show a different rate.

Answer: (C)

When you don’t have a direct measurement comparing fossil-rate changes to modern populations, the safest takeaway is that the same rate of change seen in the fossil record could also apply to modern populations. This interpretation is plausible because the same evolutionary forces—mutation, selection, drift, and gene flow—could produce similar changes under comparable conditions and timescales. It doesn’t claim certainty about modern rates, nor does it demand that fossil rates must govern modern populations, nor does it say modern populations will definitely differ. The other options overstate or misread the evidence: fossil data can still inform about possible rates and constraints, and it isn’t logically required that modern rates be different or that fossil rates must dictate modern change.
