How do fossils show evolutionary relationships?

Answer 1

Fossils are remains of ancient beings that has been preserved in rock for billions of years. Within many layers of rock are these fossils. The deeper the fossil, the older it is. By looking at the remains of different beings from different time period, we can track similarities in different remains to see how a specimen has evolved over the years to suit its environment better. Such goes their relationship between fossils and evolution. Through this process, scientist have actually found that we have a common ancestors with monkeys and therefore we didn't actually didn't come from apes in case you wanted an example :)
