There is very little fossil evidence for the first 4 billion years of Earth.
Most of the fossil evidence is from the last 600 million years of Earth.
The fossil record is not complete.
Explanation:
Fossils are the preserved remains of organisms that have died and decayed. They are very useful in understanding the evolutionary history of organisms and to study ancient life forms.
Geologists use fossils to date sedimentary records by placing them in the order of their specific appearance.
The earth is about 4.5 billion years old.
The earliest know fossils have been dated about 3.7 billion years.
The bulk of these fossils are micro-fossils and are not so much abundant.
There is very little fossil evidence for the first 4 billion years on earth.
It was during the Cambrian radiation that life form diversified and exploded.
This is why most fossils are from the last 600 million years.
