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
How are derived characters used to show evolutionary relationships?
I believe it is a cladogram.
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)
The science that seeks to show evolutionary relationships between organisms is?
The science is called phylogenetics. It uses molecular data and morphology to study the evolutionary relationships and the patterns of descent among different organisms. Phylogenetic trees are commonly used to illustrate these relationships.
What is the branch of geology that studies fossils?
Paleontology is the branch of geology that studies fossils. It focuses on the understanding of ancient life forms and their interactions with the environment to interpret Earth's history. By examining fossils, paleontologists can reconstruct past ecosystems, evolutionary relationships, and environmental conditions.
What are the key differences between gene trees and species trees, and how do these differences impact our understanding of evolutionary relationships?
Gene trees represent the evolutionary history of a specific gene, while species trees show the evolutionary relationships between different species. The key difference is that gene trees can show conflicting patterns due to factors like gene duplication and loss, while species trees aim to reflect the overall evolutionary history of a group of organisms. Understanding these differences is crucial for accurately interpreting evolutionary relationships and patterns of genetic inheritance.
What is the main purpose of a cladogram?
A cladogram is a diagram used in biology to show evolutionary relationships between different species. It helps scientists understand how different species are related based on shared characteristics and can be used to study patterns of descent and common ancestry.
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 is cladistics used to reveal evolutionary relationships between organisms?
Cladistics analyzes shared characteristics in organisms to group them into evolutionary related categories called clades. By identifying shared derived characteristics among species, cladistics can reveal the evolutionary relationships and common ancestry between organisms. This method helps to construct evolutionary trees that show the branching patterns of species over time.
How could a study of these embryos help show the relationships among animals with backbones?
Studying embryos of animals with backbones can help elucidate evolutionary relationships by identifying similarities and differences in developmental processes. By comparing developmental stages and gene expression patterns, researchers can infer common ancestry and evolutionary relationships among different species. This information can provide insights into the evolutionary history of vertebrates and help reconstruct their phylogenetic relationships.
