fossils are the remains of the living organisms that existed a long time ago. They are well preseerved by nature and are vital for us as they enable us to know about the living conditions in which they existed. They tell us about the phases of evoultions through which they must have undergone in order to sustain themselves in the competetive environment. The fossils can tell us about the species's evolution and its adaption towards the environmental condition and thus help us in understanding the natural selection easily. natural selection is the theory given by Darwin about the evolution of species.fossils are the remains of the living organisms that existed a long time ago.

∙ 14y agoFossils tell us several things. By examining them, we can see the structure of animals in early times and how they probably lived. An animal with sharp teeth probably was a carnivore since that is used well when eating meat.
In terms of Evolution, it tells us how animals evolved, but they can also help disprove it. Evolution says that animals have slowly evolved from one species to another. If this is true, why are there no fosils of animals between species?

∙ 14y agoConsider the ancestors of terrestrial vertebrates. These creatures date back to the Permian--Acanthostega, and other early amphibians. At that time these were the only animals on the surface of the earth, all other life was either early primitive terrestrial plants and insects, or living in the ocean.
In the oceans there were sarcopterygian lungfish which looked very much like these early amphibians. Very close resemblance. Paleontologists infer the fishes were the ancestors of these early amphibians, and that the amphibians were ancestral to sail backed reptiles that followed, and so on. One can chart fairly gradual sequences of changes through species over time.

How did fossil affect what people thought about creature on Earth?
Fossils affect how people think about ancient creatures of Earth. The fossils show animals that people did not previously know existed.
How do fossils show that rock at the top of mountains was once under water?
Not all fossils prove that a mountain top or any place was once under water.
How do fossils show us that environmental conditions have changed?
It is not so much the fossils themselves but the fossil record that show us that the environmental conditions have changed. The evolution of the Earth's Biosphere (living things, the oceans, land surface and atmosphere) began about 3600 million years ago when the atmosphere and oceans had no free Oxygen in them. The first life on Earth (blue green alga and 'stromatolites) slowly produced Oxygen and these are the only fossils we find from this time. As oxygen was produced over the next 3000 million years, it caused iron to be deposited out of the sea water (forming our banded Iron ore deposits) and slowly changing the atmosphere. As the Oxygen built up more complex life forms developed and by 5-600 million years ago the fossils of hard shelled sea creatures are found. Slowly more and more oxygen was released from the sea into the atmosphere and at about 425 million years ago we begin to see the fossils of the first land plants. Animals then began to follow the plants out of the seas onto land and we see fish and amphibian fossils then came the age of the reptiles (dinosaurs) and as we get nearer to the present more and more and more varied animals are found as fossils. Thus Life CREATED the Environment and the fossils prove this. They can be in cold climates or be in hot weather. It depends what their climate is. (:
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.
Fossils show that there have been many?
Fossils show that there have been many plants and animals that no longer exist.
What can fossils tell you about how life changed through time?
Yes, they can show you life back then compared to now. Also the dirtier the fossil the older the fossil.By:Donny Heitler
How do fossils tell the story of earth?
because they show what was once on the earth
How do fossils show how organisms have evolved through time?
Fossils provide valuable evidence of how organisms have evolved over time. By studying the structure, shape, and characteristics of fossils, scientists can observe unique features that have changed or stayed the same. Fossils also help in understanding the transition from one species to another and provide a record of extinct species, giving insights into the diversity of past ecosystems and the evolutionary journey of life on Earth.
Why is it important to trace the ancient organism?
Because fossils are the preserved remains or traces of animals,plants,and others organism from the past.fossil are iportant evidence for evolution because they show that life on earth once different from from life found on earth today.
How did fossil affect what people thought about creature on Earth?
Fossils affect how people think about ancient creatures of Earth. The fossils show animals that people did not previously know existed.
How do fossils help geologists?
Fossils help geologists discover new species. Fossils also explain and show the age of the specimen and change in life forms.
How do fossils show that rock at the top of mountains was once under water?
Not all fossils prove that a mountain top or any place was once under water.
Does radioactive decay give evidence that the earth has changed?
Information on radioactive decay is used for radiometric dating. It can be used to determine the ages of rocks, fossils, and younger organic materials. Clearly, the earth has changed, and the dating of materials on the earth show this. In the really old times, the surface of the earth had no plants. Over time, the plants developed on the earth, and then came animals. Dominant forms came and went, and all this is in the record, dated to some extent by techniques that use radioactive decay rates. Even the rocks, untouched by life, have changed, and this also can be dated based on decay rates.
How can sedimentary rocks show earth history?
they have fossils and pieces of the environment from the past inside of them
Which type of rock is likely to show ripple marks and fossils?
Sedimentary rocks show fossils, because of pre-existing life forms. They also show ripple marks due to weathering and erosion...

How does the fossil record show us how life and the environment have change on earth?
because all of the animals have changed and died off if they earth didnt change they would proably still be here now !!
