What factors made evolution move slowly for the first two billion years of life on earth?

Two factors, both related to the availability of energy and presence of mutagens.
First, the sun was much dimmer two billion years ago; it provided about 30% less heat, and less radiation. Second, there was very little free molecular oxygen in the atmosphere. Most organisms were anaerobe. Oxygen-based metabolisms are much more energetic than anaerobe metabolisms, and on top of that, oxygen-based chemistry provides much more free radicals, which act as mutagens. So life back then was slower, as well as mutation rate.

What are the factors in the evolution and diversity of life on earth?

What is the significance of evolution?
The significance of the process of evolution is that it led to life as we know it. Wheter or not we believe that evolution was guided by God or some other deity, without evolution there would only be the simple organisms that first developed on Earth over a billion years ago.
How long the prokaryotes populated Earth before the evolution of eukaryotic cells which are more complex?
* 3.5 billion years ago the first life arose: prokaryotic bacteria * 1.5 billion years ago eukaryotic cells arose Therefore, prokaryotes were present on earth for 2 billion years prior to the emergence of eukaryotic life.
What is mirco evolution?
micro evolution refers as evolution occurred during biochemical synthesis in primitive earth as for evolution of essential micro and bio molecules.
Where did evolution occur?
The only known instance of evolution occurring is here, on Earth. Logic dictates, however, that evolution occurs wherever there is life.

How old the earth today?
The Earth is estimated to be around 4.54 billion years old. This age is based on radiometric dating of meteorite material.
What are two natural factors that change earth's surface slowly and two natural factors that can change earth's surface rapidly?
your mum is the answer to the question
When was the earth created according to evolution?
Evolution does not make any regard to the origin of the earth. It only deals with the development of existing life. Geological and physical sciences teach that Earth formed approximately 4.54 billion years ago.
The three major factors though to control the evolution of the earth?
weather, movement of plates,
What factor made evolution moves very slowly for the first two billion years of life on earth?
Anaerobic metabolisms and asexual reproduction
Did evolution play during Cenozoic era?
Of course. Evolution has happened ever since life first came into existence on Earth, some 3.5 billion years ago.
What would the earth be like if this creature - man - were to become extinct?
If the creature you refer to is man, its a question of when not if. When we're gone, bacteria will slowly break down the poisons we leave behind,and evolution will continue.Biodiversity will increase again.There's still about 4 billion years to go.Man is only a fleeting moment in the colossal age of the earth.

What is the next step in your suns evolution?
The sun is currently half the age it will live for. in about another 5 billion years when the sun reaches the end of its life cycle, it will turn into a red giant, engulfing all of the rocky planets. for example earth. and then it will slowly cool and become a white dwarf.
Where does evolution start?
Evolution begins with self replication. Evolution on Earth began around four billion years ago. We don't have any record of that long lost microscopic beginning, but it may have been a single molecule that could make copies of itself.
