how fossils records give us information about evolution???
Answers
Answer:
Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.
Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.

Answer:
1) There are many types of evidences of evolution from which fossils occur in paleontological evidences.
2) Deepest layer of soil gives oldest organism's fossil, Slightly upper layer of soil gives older organism's fossil and upper layer of soil gives old organism's fossil.
3)When organism is alive, it constantly consumes carbon from which C-12 and C-14 are the isotopes of carbon which are used in Carbon Dating method.
4) The C-14 isotope of carbon is radioactive, so it releases from the body when the organism is dead.
5) The ratio of C-12 and C-14 is fixed in living organisms. As the C-14 releases from the body, the ratio changes from which we can determine that how long ago that organism existed.
6)In this way fossil record gives us information about evolution.
