Clues can be found out about the evolutionary relationships of animals by studying fossil records.
Fossil records contain radiation, and the older the fossil is, the less radiation it gives off. Scientists study how much radiation is in the fossil record, and they find out how old the earth is.
The evidence scientists have are fossil clues, plant clues, climate clues and rock clues. Fossil clues supported the idea because a certain fossil the Mesosaurus was found in two continents on opposite sides of the Earth and the only reason for that is if the lands came together at one time. Plant clues support the idea the same way fossil clues do, like the plant called a Glossopteris was found in different areas around the world. Climate clues support the idea because some of the fossils and plants from warmer climates were found in the Arctic. That explains why there are glaciers in tropical areas. Lastly rock clues support the idea because if the continents were once connected at one time, then the rocks that made up the continents should be in the same locations where they were joined.
If he is giving you clues then give clues back. There are no certainties in relationships, no one can make it perfect for you. Relationships are not just about how you feel.
