Fossils of an ancient reptile called Lystrosaurus have been found in Africa, India, and Antarctica. Which of the following best explains this distribution?
- They were able to move between continents before the oceans filled.
- The movement of India due to continental drift carried them from place to place.
- These land areas were once next to each other and have since drifted apart.
- They were able to migrate over frozen seas during Ice Ages.
- Changes in climate forced them to migrate from place to place.
Answer(s): C
Explanation:
The best evidence to support the finding of fossils on widely separated land masses comes from continental drift theory, which states that certain land areas had been connected and slowly drifted apart this would allow for separation of what were once continuous species' ranges. It is highly unlikely that a reptile species could have moved easily between continents or could have survived frozen seas during the Ice Ages.
