Detailed explanation-1: -Fossil Evidence One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined.
Detailed explanation-2: -There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be: The species evolved independently on separate continents – contradicting Darwin’s theory of evolution.
Detailed explanation-3: -Plant and animal fossils also reveal evidence. There are various examples of fossils found on separate continents and in no other regions. This indicates that these continents were once joined together because the extensive oceans between these land masses act as a barrier for fossil transfer.
Detailed explanation-4: -Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics.
