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 :)

How do fossils show changes in related species?
Fossils are used to show changes because they are permanent. These fossils are also old and show evolutionary changes in species alive today.
Is a type of evidence used by scientists to determine evolutionary relationships?
The evidence do scientist use to determine evolutionary relationships by scientist have combined the evidence from DNA, protein structure, fossils, early development, and body structure to determine the evolutionary relationship amoung species.
Does a dichotomous key show evolutionary relationships among organisms?
yes
What is the main purpose of a cladogram?
To show evolutionary relationships based on traits
How are derived characters used to show evolutionary relationships?
I believe it is a cladogram.
The science that seeks to show evolutionary relationships between organisms is?
Systematics is the scientific study of the diversity of organisms and their evolutionary relationships. The science of naming, classifying, and describing organisms is called taxonomy.
Explain the importance of fossils in deciding evolutionary relationships?
We can look at fossils to determine what physical characteristics each organism had and compare them to other organisms to see what characteristic's they have in common or how the changed (evolution)
Where can clues in the evolutionary relationships of animals be found?
Clues can be found out about the evolutionary relationships of animals by studying fossil records.
How do scientist use cladograms?
To show evolutionary relationships based on traits
How does the biogeography of fossils support evolutionary?
Modern plants and animals resemble fossils found in the same area.
How does the position of fossils in layers show evolutionary changes?
Assuming the layers aren't deformed, the lowest deposition layers are the earliest. Later deposition layers accumulate on top of the earlier layers. Thus, the lowest layers have the earliest fossils, and the highest layers have newer fossils. By comparing the features of early and late fossils of a species, you can determine some of its evolutionary changes. Of course, not all features survive in a fossil - soft tissues, for example.
What do phylogenic trees show?
Phylogenic trees show evolutionary relationships between organisms. The branches reflect the hierarchical classification of groups within more inclusive groups.
