Using the principle of faunal succession, if an unidentified fossil is found in the same rock layer as an index fossil, the two species must have existed during the same period of time (Figure 4). If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time.
Answer:
I believe this is from the SimBio virtual lab tutorials. The options are

Answer:
Explanation:
That's quite a bit of points. Offer 20 next time (which shows up as 10).
Not all experiments lend themselves to this, but the best ones do. Make predictions. The startling experiments (the best of them) certainly allow you to make predictions
Most of the time, experiments confirm what was originally thought. It is, however, the best answer among this bunch.
A is also possible, but not always. I will stick with D, but I think others will pick A.
