Replication is a process in which DNA molecule is copied, and thereby two identical DNA molecules are produced. Complementarity is achieved through interactions between nucleobases. In the DNA, base complements are adenine - thymine (A-T) and guanine - cytosine (G-C).

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 dead and decayed organisms usually found in rock strata in nature.
Special conditions must be made available for an organism to be fossilized. The presence of hard part and suitable environmental condition ensures that an organism is fossilized.
- Since not all organisms can be fossilized, and the earth is dynamic in nature, most of the fossil records are not complete. Agents of denudation typically truncates fossil sequences in rocks.
- The oldest fossil has been date to be about 3.7 billion years. Most of these fossils are micro-fossils and are not very well abundant.
- There is little fossil for the first 4 billion years on earth.
- The cambrian radiations produced diversities of life about 600 million years ago and provided a very decent amount of fossils in the geologic record.
