This means they can tells how plants and animals on earth used to look. Fossils are good evidence for evolution becuase they show that living things have changed over time.
Why are fossils important to scientists what scientific evidence do fossils provide?

How do fossils help geologists?
Fossils can also be used to date rocks. Through the process of evolution, different kinds of fossils occur in rocks of different ages, enabling geologists to use fossils to understand geological history. For geologists, fossils are one of the most important tools for age correlation.
What is the significance of fossils in deciding evolutionary relationships?
Fossils provide the knowledge of animals and plants that lived hundreds of years ago which are now extinct. It helps us to compare the organisms that lived in earlier times and their present descendants. They are the connecting link between two groups and help in the study of evolution.
How does fossils provide evidence for evolution?
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. … Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
How do artifacts and fossils help us understand?
Archaeologists use artifacts and features to learn how people lived in specific times and places. They want to know what these people’s daily lives were like, how they were governed, how they interacted with each other, and what they believed and valued.
Why are fossils found more often in sedimentary rock?
Fossils are found in sedimentary rocks most often. So most fossils are found in sedimentary rocks, where gentler pressure and lower temperature allows preservation of past life-forms. As for Igneous rocks they do not posses any fossilized body just because they are formed under very harsh conditions.
Why are transitional fossils important?

How do fossils help tell us about the environment of deposition?
Environment of Deposition
By knowing something about the type of organism the fossil was, geologists can determine whether the region was terrestrial (on land) or marine (underwater) or even if the water was shallow or deep. The rock may give clues to whether the rate of sedimentation was slow or rapid.
Why and how are fossils useful in understanding past climates?
Fossils that provide indirect (proxy) information on past environmental conditions are called paleo-indicators. … The presence of fossils representative of these organisms can tell us a great deal about the environments of the past; what the climate was like, and what sorts of plants and animals inhabited the landscape.
What does fossils of organisms no longer alive today tell us?

How fossils help for us to recreate the past?
Answer: By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
What is the role of fossils in supporting the theory of common descent?
How do fossils support the theory of common descent? They are a record of at least some intermediate types of organisms and thus document the process of evolution. … Layers of sediments accumulate every year, covering older fossils in more layers.
What can we learn from fossils Bitesize?
However, most of the species found in the fossil record have died out or become extinct.
