Answer:
Wegener presented a number of evidence to prove his plate tectonic theory, such as :

- His knowledge hat organisms such as freshwater reptiles were found in almost all continents
- He also identified organisms that live in different continents, and could not possibly cross over to the other continents due to water bodies (oceans) separating the continents.
Wegener's plate tectonic theory caused doubts to other scientists, because of the way he presented his evidence. Other scientists considered his mechanisms unrealistic
Explanation:
Cephalization describes the process by which organisms develop a distinct head. The head of a cephalized organism contains a concentrated group of nerves, or brain, that controls the rest of the organism, as well as specialized organs for consumption and perception, like mouths, eyes and ears. Cephalized organisms exhibit a distinct division between parts of the body; they have a front, back, top and bottom. These animals comprise the bulk of animals that are encountered on a daily basis.
