What can fossils tell scientists about Earth’s past?
Fossils are the remains or traces of ancient life that are usually buried in rocks. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.
What can fossils teach us about Earth’s history?
Fossils give us a useful insight into the history of life on Earth. They can teach us where life and humans came from, show us how the Earth and our environment have changed through geological time, and how continents, now widely separated, were once connected.

How did fossil help and teach scientists about the history of the earth?
The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era. It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.
How can fossils teach scientists about different landforms and about Earth’s history?
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.
How can fossils help scientists?
Studying fossils helps them learn about when and how different species lived millions of years ago. Sometimes, fossils tell scientists how the Earth has changed.

How do rocks and fossils tell us about the way Earth changes over time?
The oldest rock layers are at the bottom and the newest layers are at the top. We can tell about the Earth's history by looking at the different layers. The upper layers, those that are closest to the surface of the Earth, are the newest layers to be laid down. Layers below are older.
Why are fossils important evidence for evolution?
Key Points. Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
How do we know about Earth’s past?
Historical geologists study the Earth's past. They use clues from rocks and fossils to figure out the order of events. They think about how long it took for those events to happen.
What can we learn from fossils?
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 can kids learn from fossils?
Fossils are the remains or traces of plants and animals that live a long time ago. Fossils help scientists understand what life was like millions of years ago. Some fossils provide evidence of living things that have gone extinct, which means they no longer found alive anywhere on earth today.
What can rock fossils and original remains show about Earth’s past?
Fossils and other natural evidence show changes in life and the environment. Fossils reveal that Earth has undergone many changes over billions of years. Scientists study fossils to learn what organisms and animals once lived in places where the fossils were found.
Why are fossils important to scientists what scientific evidence do fossils provide?
Why are fossils important to scientists? They provide useful information to identify evolutionary things within organisms over time. They gather information from it to provide evidence of the characteristics of ancient environments and geography.
What do fossils show about evolution?
Fossils are direct evidence of evolution. It tells about the life found on ancient earth. By studying fossil records palaeontologists reveal the connecting link between different organisms of the past and present. The fossils present in the different layers of earth determine the age of the organisms.
How do scientists use fossils to draw conclusions about the evolution of life on Earth?
Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories of present-day species.
Why are fossils helpful in studying the prehistoric past?
They are a tangible connection to life, landscapes, and climates of the past. They show us how life, landscapes, and climate have changed over time and how living things responded to those changes. Those lessons are particularly important as modern climate continues to change. All fossils are irreplaceable!
How are fossils evidence for evolution?
Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories of present-day species.

How do scientists study the Earth’s past?
Clues about the past climate are buried in sediments at the bottom of the oceans and lakes, locked away in coral reefs, frozen in glaciers and ice caps, and preserved in the rings of treesTo extend those records, paleoclimatologists look for clues in Earth's natural environmental records.
How do fossils and rock layers tell the story of life on Earth?
The location of fossils in rock layers provides evidence of Earth's past landscapes. It is hard to guess the age of rock. Scientists have to act like detectives, piecing together a mystery to determine how long ago rocks formed. Fossils found in a particular rock layer help scientists determine the age of the rock.
What are fossils why do they tell us about process of evolution?
Fossils are important evidence for evolution because fossils show that life on this Earth was once very different from the life found on the Earth today. > By comparing the morphological, anatomical characteristics of modern species and fossils, paleontologists can infer the lineages of modern species.
What is the fossil record and why is this used as evidence for natural selection?
The fossil record is a revealing window into species that lived long ago. Paleontologists have carefully analyzed the preserved remains and traces of animals, plants, and even microorganisms to reconstruct the history of life on Earth (see the History of Life chapter for more detail).
How fossils help for us to recreate the past?
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 are the importance of fossils?

What type of evidence for evolution is provided by fossils?
Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories of present-day species.
How fossils provide evidence of change from the earliest life forms to those alive today?
They provide evidence of change from the earliest life-forms to those alive today as fossils can contain records such as teeth structure of the dinosaurs to make assumptions on their diet and compare how these trait evolve throughout time.
