Fossils.
Early in the 20th century, Alfred Wegener, primarily, established the continental drift theory. According to Wegener, continents are mobile on the surface of the Earth and were previously connected to form a single supercontinent. Scientists did not think that the continents could migrate when Wegener was alive.
In rocks that are the same age but on continents that are currently far apart, ancient fossils of the same species of extinct plants and animals can be found. Wegener claimed that the species had coexisted, but that once they died and become petrified, the lands had separated. According to his theory, the creatures couldn't have crossed the seas.
1. Glossopteris seed fern fossils were too heavy for the wind to carry them that far.
2. Mesosaurus was a reptile that could swim, although it could only do it in freshwater.
3. The terrestrial reptiles Cynognathus and Lystrosaurus were incapable of swimming.

Answer:
C. Resource partitioning of the seeds reduces competition, and the five different species can live in the same tree
Explanation:
Generally, living organisms tend to compete for resources such as food and water. However, to restrict competition, resource partition is used. Resource partitioning is the breaking down of scarce resources to prevent competition in a niche. Therefore, as a result of resource partition that occurs due to limited resources, the competition among the species is reduced.
