If a supercontinent did not exist, it could be possible for fossils of the same life form species to be found on continents that are now divided by oceans through the process of plate tectonics. Over time, the continents have moved and shifted positions, bringing the fossils of the same species along with them.

If fossils of the same life form species have been found on continents that are now divided by oceans, it could be possible if these continents were once connected as part of a supercontinent and later separated due to plate tectonic movements.

To answer this question, you need to consider the concept of continental drift. Explain that the existence of fossils from the same species on continents separated by oceans can be explained by the theory of continental drift. Suggest that when the supercontinent Pangaea existed around 200 million years ago, the continents were once joined together. Over time, these continents separated and moved apart due to tectonic plate movements. As a result, fossils of the same species can be found on continents that are now divided by oceans. The answer should clearly explain this concept in one to two sentences, providing enough details to support the explanation. It is essential to avoid grammar, usage, or mechanics errors that could interfere with the meaning of the answer.
