The image shows that landmasses now separated by oceans fit together like puzzle pieces and have fossils of the same organisms. these clues are evidence of

continental drift theory

Explanation:

If we take the shapes of the continents and we compare them, and put them next to each other, we can see that they are an almost perfect match, and that they resemble a puzzle. Also, it is very interesting that there are lot of fossils that are exactly the same, thus the same species, found in multiple different continents. These two clues give us part of the evidence that the continental drift is a real process that has been going on since very early in the geological timeline.
