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.
- Most of the fossil record is incomplete.
- Not all organisms are properly preserved.

Answer -
RNA - Stands for (ribonucleic acid)
The difference between RNA and DNA is difference in sugar and the make up of the back bone. For example in DNA it has deoxyribose (hint) why its called deoxyribonucleic which is one less O2 then ribose.
In addition they have different back bones in which are in
DNA its adenine, guanine, cytosine, thymine.
RNA its adenine, guanine, cytosine, uracil.
Can make a big difference trust me with those compounds.
Resources are depleted population growth rate slows and eventually stop this is known as the logistic growth the population size at which growth stops is generally called the carrying capacity which is the number of individuals of a particular population that that environment can support.
